Elementary School Science Fair Project Guide
by Science Explorers | Dec 5, 2018 | Blog | 0 comments
Science fair projects are activities that are both fun and educational for students. They can pick topics that pique their curiosity, test their hypotheses by creating their own experiments and learn how to use the scientific method — a practice used by professional scientists around the world.
However, there are many steps to take to make this project a success, and we’re here to guide you through each one of them.
What Is a Science Fair?
A science fair refers to an event, often held in elementary schools, where students share experiments that they’ve conducted and the results that they have found. In some fairs, students will compete for prizes, while others are less competitive.
Science fairs in the U.S. can be traced back to the E.W. Scripps’ Science Service. The mission of this organization, which was established in 1921, was to increase interest and awareness of science by teaching scientific concepts in simpler, less technical terms. This organization was instrumental in organizing the Science Clubs of America, which in 1950 held a national science fair for the first time.
How to Make an Elementary School Science Fair Project
Follow these steps to get your scientific investigation underway:
- Pick a topic you love: You’re much more likely to enjoy this process — and do it well — if you pick a topic you’re passionate about. Don’t limit yourself to scientific topics, but rather think of your most intense interests and how they can be related to science . A science experiment can be created using practically any topic. For instance, if your passion is art, you could investigate the reaction of paint chemicals or how to make artificial colors. Choose a topic that is suitable for your age. While you can pick a topic that is challenging, you don’t want to choose a topic so difficult that you can’t complete it in time.
- Think of a question: Once you’ve decided on your topic, think of a question that you can test .
- Formulate a hypothesis: A hyp othesis is an attempt to answer your question.
- Think of a procedure: A procedure is an experiment that can be conducted to affirm or deny your hypothesis.
- Acquire materials: Once you know how you’ll conduct your experiment, start gathering materials you’ll need to do it.
- Record r esults: By experimenting, you can see if your hypothesis was correct.
- Arrive at a conclusion: Take a good look at the result you got, and determine whether your hypothesis was right or wrong. Also, think of ways you could further explore the question. As you’re doing your experiment, take notes so that afterward you can more easily share what you did and what you learned.
How to Prepare Your Poster
After you’ve finished your experiment and drawn your conclusions, the project is only halfway done — now you create a poster that provides a clear overview of what you did.
Creating Your Display Board
Elementary school students create posters with basically the same format as those presented by professional scientists at conferences. In general, display boards at science fairs are tri-folds, meaning that they’re folded on both sides so that they can easily stand. It’s not uncommon for boards to measure up to 14 inches deep and 3 feet wide. You can find these boards at office supply, craft and drug stores, or you can make your own with cardboard or poster board.
If you decide to make one yourself, it’s probably best to create three separate pieces then attach them with duct tape so that they can easily bend.
Organizing the Display Board
When it comes to organizing your poster, you’ve got several options. However, no matter you decide to do the layout, make sure that it includes these key sections:
- Title: When writing your title, you can simply go with your question or some other message that grabs your audience’s attention.
- Question: Clearly state your question. Also, provide some background why this topic interests you and how you thought up the question.
- Hypothesis: Tell your audience what you guessed the results would be before you conducted the tests.
- Procedures: Clearly explain the steps you took to test your question and why you decided on that procedure.
- Equipment and materials: Include a list of the things you needed for your test.
- Data and results: Describe what happened when you conducted your experiment. Use graphs, charts or other visuals to help convey your results.
- Conclusion: In your previous step, you just described the data. In this step, you want to make sense of them. Mention whether your hypothesis was correct or not, and explain why you think you got those results. Also, if you were to redo the tests, mention what you would do differently.
- References: Include the resources you used, whether they’re websites, books or people.
- Your Name: Also add your grade and the name of your teacher.
Below is an example of a science fair project, including a detailed account of the procedure, results and conclusions.
“Keeping Flowers Beautiful”
2. Question
“What Solution Can Keep Flowers Fresh for the Longest Period of Time?”
I chose this topic for several reasons. First of all, I love flowers, and I’m always trying to figure out better ways to keep them fresh for longer. Also, this issue is of great importance to many industries and consumers since they buy flowers for many occasions including weddings, Valentine’s Day, Mother’s Day and Christmas.
Flower shops often provide customers with an additive to put in the water in their vase, but I wanted to question whether this additive is the most effective solution and whether another could work better. In my project, I tested homemade solutions, commercial preservatives and old wives tales.
3. Hypothesis
I believe that some home remedies will be just as effective as the preservative provided by florists. I hypothesize that the most effective solution will be lemon-lime soda because it contains sugar as well as several chemicals that I believe will inhibit the growth of bacteria that could damage the plant.
4. Procedures
Follow these steps to test your hypothesis:
- Thirty (30) daisies (bellis perennis) will be bought from the same store at the same time to make sure they are all equally fresh.
- Using a lab coat, gloves and goggles, certain solutions will be mixed together in 10 one-pint jars with an 8-ounce measuring cup, a tablespoon and a teaspoon. To avoid contamination, wash hands after making each mixture.
- The solutions used are tap water, distilled water, tap water with a teaspoon of salt, tap water with an aspirin pill, lemon-lime soda, tap water with 1 tablespoon of bleach, tap water with 1 tablespoon of sugar and 1 tablespoon of cider vinegar, tap water with 1 tablespoon sugar, tap water with 1 tablespoon of mouthwash and tap water with 1 tablespoon of commercial preservative Floralife.
- The stems of the flowers will then be submerged in lukewarm water and clipped at a 45-degree angle. Afterward, they will be put into the solutions. Three specimens will be placed in each of the 10 solutions.
- Every other day, the stems will be cut again and put in fresh solutions. These are considered good florist practices.
- The state of each flower will be examined once a day until either 14 days have passed or nothing remains in the vases. The number of specimens remaining in every solution will also be documented every day, as will their color and droopiness.
- Once their state has been recorded, specimens that are wilting, drooping or browning at the edges will be removed so that the bacteria won’t harm the other specimens in the container.
- A chart that shows how long each specimen stayed fresh will be made, accompanied by photos of the changes.
5. Equipment and Materials
Here’s what you’ll need for this experiment:
- Ten 1-pint jars to contain the flowers in the solutions
- A teaspoon measure
- A tablespoon measure
- An 8-oz. cup measure
- A pair of gloves
- A protective lab coat
- Distilled water
- 30 cut daisies (bellis perennis)
- A 1/2 cup of cider vinegar
- 12 cans of lemon-lime soda
- A 1/2 cup of sugar
- A 1/2 cup of Floralife
- A 1/2 cup of bleach
- A 1/2 cup of mouthwash
6. Data and Results
- In the tap water, mouthwash and aspirin solutions, the flowers stayed fresh for seven full days. Every other homemade solution that I used in my project caused the flowers to wilt faster.
- By 14 days, the freshest specimens were the ones in the sugar water. One of the flowers in the lemon-lime soda solution browned in the middle, as did all of the Floralife specimens.
- By 21 days, the specimens in the sugar water still had not browned, although they had significantly wilted. The specimens in the soda had wilted. The Florarlife specimens still had the brown color, but no wilting of the petals occurred.
7. Conclusion
My hypothesis that the lemon-lime soda would be most effective was incorrect. The specimens in the soda, the floral additive and sugar water solutions all remained at Stage 1 for seven days and fresh enough for display for a full 21 days.
Although Floralife research suggests that it is more effective than any alternative, my results showed that both lemon-lime soda and sugar water can help keep flowers fresh for the longest time. This suggests that florists and consumers could save by using sugar water instead of the more costly floral preservatives.
Science Fair Project Ideas
If you’re having trouble coming up with a topic that interests you, below are some science fair ideas for inspiration:
- Soaking pennies: A long-time favorite of elementary school students, dirty pennies are collected in this experiment and soaked in a variety of acidic liquids such as lime juice, lemon juice, vinegar and salsa. This experiment is best for kindergartners or first graders.
- Creating circuits: Students interested in technology can make simple circuits using everyday objects. This is also most suitable for kindergartners or first graders.
- Rainbow rubber eggs: This fun experiment involves submerging eggs in vinegar, adding a few drops of food coloring and waiting a few days to see some cool results.
- Teleidoscopes: These objects are like kaleidoscopes but do not have an end, allowing you to view anything you want. Looking through one of these is a fantastic experience. This project is most appropriate for kids between second and fourth grade.
- Density tower: This experiment involves layering liquids of different densities on top of one another without having them mix together.
- Growing salt crystals: Salt crystals can be grown overnight in the fridge.
General Tips
In addition to the necessary steps mentioned above, we’d also like to share some general tips to boost the quality of your presentation.
- Document everything: Through the entire process, record all your activities, thoughts and findings in a journal. Some science fairs actually request that you include your notebook as part of your presentation. For professional scientists, keeping a detailed log of their experiments is critical.
- Write on separate pieces of paper: It’s much easier to write all titles and other text on pieces of paper and then glue them to your board than to write directly on the board. You can also type them out with a computer and use attention-grabbing colors and fonts — just make sure that the font and font size are easy to read from a few feet away.
- Take photos: One of the easiest ways to help explain the process is with pictures, so remember to keep a camera nearby and take photos throughout the experiment. Then, print out your best photos and include them on your board — breaking up the text with pictures will make your project easier to digest.
- Make it colorful: If your teachers allow it, consider buying a colorful board. Other ways to add color include printing out your titles and text on colored construction paper, scrapbook paper or cardstock. You can also make your project pop with stickers, cut-out letters or colored paper.
- Lay everything out before pasting: Before grabbing the glue, first lay everything out that you want to include on your board. The hypothesis, procedures and materials should be on the right, the data and results should be in the center, and the conclusion, personal information and resources should go on the right. Depending on how much you include for each section, you may need to adjust this layout. Once you’re happy with the placement of everything, paste it to the board.
- Use glue dots or glue sticks: These two types of glue are the easiest to use. You can use regular glue as well, but it sometimes causes wrinkles in the paper and can be difficult to change the position of things after the glue has dried.
- Limit parental involvement: Parents should give their children the opportunity to do as much of the work as they can for their age. Although requirements vary from school to school, parents are usually allowed to type up the notes their children have made — just make sure that your child is telling you what to write. Your child should be able to explain every step of the process to the panel of judges. It’s a good idea to have your kids practice explaining what they did to you or other members of your family.
How Does the Judging Work?
Some science fair projects are assessed by a panel of judges and the winners may advance to regional or state levels. At elementary school science fairs, however, it’s less common to award placements. Instead, judges may point out the best parts of each project, award ribbons and leave commentary. At the elementary level, the objective is usually to just encourage students to continue participating in these events.

The Ultimate Science Fair Project Guide – From Start to Finish
When our daughter entered her first science fair, we kept seeing references to the Internet Public Library Science Fair Project Resource Guide . However, the IPL2 permanently closed… taking the guide with it. Bummer ! After now participating in over a half-dozen elementary school science fairs (including a first-place finish!), we created our own guide to help other students go from start to finish in their next science fair project. If this is your first science fair, have fun! If you’ve done it before, we hope this is your best one! Let’s science!

How to Use the STEMium Science Fair Project Ultimate Guide?
If you are just starting off and this is your first science fair, here’s how to get started:
- Start with the STEMium Science Fair Project Roadmap . This is an infographic that “maps” out the process from start to finish and shows all the steps in a visual format.
- Getting Started – Why Do a Science Fair Project . Besides walking through some reasons to do a project, we also share links to examples of national science fair competitions, what’s involved and examples of winning science fair experiments . *Note: this is where you’ll get excited!!
- The Scientific Method – What is It and What’s Involved . One of the great things about a science fair project is that it introduces students to an essential process/concept known as the scientific method. This is simply the way in which we develop a hypothesis to test.
- Start the Process – Find an Idea . You now have a general idea of what to expect at the science fair, examples of winning ideas, and know about the scientific method. You’re ready to get started on your own project. How do you come up with an idea for a science fair project? We have resources on how to use a Google tool , as well as some other strategies for finding an idea.
- Experiment and Build the Project . Time to roll up those sleeves and put on your lab coat.
- Other Resources for the Fair. Along the way, you will likely encounter challenges or get stuck. Don’t give up – it’s all part of the scientific process. Check out our STEMium Resources page for more links and resources from the web. We also have additional experiments like the germiest spot in school , or the alka-seltzer rocket project that our own kids used.
Getting Started – Why Do a Science Fair Project
For many students, participating in the science fair might be a choice that was made FOR you. In other words, something you must do as part of a class. Maybe your parents are making you do it. For others, maybe it sounded like a cool idea. Something fun to try. Whatever your motivation, there are a lot of great reasons to do a science fair project.
- Challenge yourself
- Learn more about science
- Explore cool technology
- Make something to help the world! (seriously!)
- Win prizes (and sometimes even money)
- Do something you can be proud of!
Many students will participate in a science fair at their school. But there are also national competitions that include 1000s of participants. There are also engineering fairs, maker events, and hackathons. It’s an exciting time to be a scientist!! The list below gives examples of national events.
- Regeneron Science Talent Search
- Regeneron International Science and Engineering Fair
- Google Science Fair
- Conrad Challenge
- Microsoft Imagine Cup
- JSHS Program
- Exploravision
What’s the Scientific Method?
Before we jump into your project, it’s important to introduce a key concept: The Scientific Method . The scientific method is the framework scientists use to answer their questions and test their hypothesis. The figure below illustrates the steps you’ll take to get to the end, but it starts with asking a question (you’ve already finished the first step!).
After we find a problem/idea to tackle, and dig into some background research, we create a guess on a potential solution. This is known as our hypothesis.
Example of a Hypothesis
My brother can hold his breath underwater longer than I can (“our problem”) –> how can I hold my breath longer? (“our question”) –> if I drink soda with caffeine before I hold my breath, I will be able to stay underwater longer (“our solution”). Our hypothesis is that using caffeine before we go underwater will increase the time we hold our breath. We’re not sure if that is a correct solution or not at this stage – just taking a guess.
Once we have a hypothesis, we design an experiment to TEST our hypothesis. First, we will change variables/conditions one at a time while keeping everything else the same, so we can compare the outcomes.
Experimental Design Example
Using our underwater example, maybe we will test different drinks and count how long I can hold my breath. Maybe we can also see if someone else can serve as a “control” – someone who holds their breath but does not drink caffeine. For the underwater experiment, we can time in seconds how long I hold my breath before I have a drink and then time it again after I have my caffeine drink. I can also time how long I stay underwater when I have a drink without caffeine.
Then, once we finish with our experiment, we analyze our data and develop a conclusion.
- How many seconds did I stay underwater in the different situations?
- Which outcome is greater? Did caffeine help me hold my breath longer?
Finally, (and most important), we present our findings. Imagine putting together a poster board with a chart showing the number of seconds I stayed underwater in the different conditions.
Hopefully you have a better sense of the scientific method. If you are completing a science fair project, sticking with these steps is super important. Just in case there is any lingering confusion, here are some resources for learning more about the scientific method:
- Science Buddies – Steps of the Scientific Method
- Ducksters – Learn About the Scientific Method
- Biology4kids – Scientific Method
- National Institute of Environmental Health Sciences – Scientific Method
What Science Fair Project Should I Do?
And science is no different.
Just know that if you can get through the idea part, the rest of the science fair is relatively smooth sailing. Remember to keep an open mind and a positive outlook . Each year 100s of 1000s of kids, teenagers and college students come up with new projects and ideas to test. You’ve got this!
What Makes a Great Science Fair Project? Start with a Problem To Solve
As we discuss below, good science experiments attempt to answer a QUESTION. Why is the sky blue? Why does my dog bark at her reflection? First, we will step through some ways to find TESTABLE QUESTIONS. These questions that you create will be what you work on for your science fair project. Pick something fun, something interesting and something that you are excited about. Not sure what that looks like? Step through some of the tips below for help.
Use the Google Science Fair Idea Generator
Are you surprised Google made a tool for science fair projects?? Our post called the low-stress way to find a science fair project gives a more in-depth overview about how to use it. It’s a great first stop if you’re early in the brainstorming process.
Answer your own questions
- What type of music makes you run faster?
- Can boys hold their breath underwater longer than girls?
- How can I be sure the sandwich I bought is gluten free?
- If we plant 100 trees in our neighborhood, will the air be cleaner?
Still stuck? Get inspiration from other science fair projects
Check out the Getting Started section and look at some of the winning science project ideas, our STEMium experiments and our Resource page. We’ve presented a ton of potential idea starters for you – take time to run through some of these, but our suggestion is to give yourself a deadline to pick an idea . Going through the lists could take you longer than you think, and in many cases sometimes it’s just better to pick something and go for it! The next section will take you through how to create testable questions for your project.
Starting Your Project: Find A Testable Question
The best experiments start with a question. Taking that a step further, the questions you useyou’re your science fair project should be ones that are TESTABLE. That means something you can measure. Let’s look at an example. Let’s say I’m super excited about baking. OH YEA!! I love baking. Specifically, baking cakes. In fact, I love baking cakes so much that I want to do a science project related to cakes. We’ve got two questions on cakes that we created. Which question below could be most useful for a science fair project:
1) Can eating cake before a test improve your score?
2) Why isn’t carrot cake more popular than chocolate cake?
The second question isn’t necessarily a bad question to pick. You could survey people and perhaps tackle the question that way. However, chances are you will get a lot of different answers and it will probably take a lot of surveys to start to pick up a trend.
Although, the first question might be a little easier. How would you test this? Maybe you pick one type of cake and one test that you give people. If you can get five people to take the test after eating cake and five people take the test with no cake, you can compare the test results. There might be other variables beyond cake that you could test (example: age, sex, education). But you can see that the first question is probably a little easier to test. The first question is also a little easier to come up with a hypothesis.
At this point, you’ve got an idea. That was the hard part! Now it’s time to think a little more about that idea and focus it into a scientific question that is testable and that you can create a hypothesis around .
What makes a question “testable”?
Testable questions are ones that can be measured and should focus on what you will change. In our first cake question, we would be changing whether or not people eat cake before a test. If we are giving them all the same test and in the same conditions, you could compare how they do on the test with and without cake. As you are creating your testable question, think about what you WILL CHANGE (cake) and what you are expecting to be different (test scores). Cause and effect. Check out this reference on testable questions for more details.
Outline Your Science Project – What Steps Should I Take?
Do Background Research / Create Hypothesis
Science experiments typically start with a question (example: Which cleaning solution eliminates more germs?). The questions might come up because of a problem. For example, maybe you’re an engineer and you are trying to design a new line of cars that can drive at least 50 mph faster. Your problem is that the car isn’t fast enough. After looking at what other people have tried to do to get the car to go faster, and thinking about what you can change, you try to find a solution or an answer. When we talk about the scientific method, the proposed answer is referred to as the HYPOTHESIS.
- Science Buddies
- National Geographic
The information you gather to answer these research questions can be used in your report or in your board. This will go in the BACKGROUND section. For resources that you find useful, make sure you note the web address where you found it, and save in a Google Doc for later.
Additional Research Tips
For your own science fair project, there will likely be rules that will already be set by the judges/teachers/school. Make sure you get familiar with the rules FOR YOUR FAIR and what needs to be completed to participate . Typically, you will have to do some research into your project, you’ll complete experiments, analyze data, make conclusions and then present the work in a written report and on a poster board. Make a checklist of all these “to do” items. Key things to address:
- Question being answered – this is your testable question
- Hypothesis – what did you come up with and why
- Experimental design – how are you going to test your hypothesis
- Conclusions – why did you reach these and what are some alternative explanations
- What would you do next? Answering a testable question usually leads to asking more questions and judges will be interested in how you think about next steps.

Experiment – Time to Test That Hypothesis
Way to go! You’ve found a problem and identified a testable question. You’ve done background research and even created a hypothesis. It’s time to put it all together now and start designing your experiment. Two experiments we have outlined in detail – germiest spot in school and alka-seltzer rockets – help show how to set up experiments to test variable changes.
The folks at ThoughtCo have a great overview on the different types of variables – independent, dependent and controls. You need to identify which ones are relevant to your own experiment and then test to see how changes in the independent variable impacts the dependent variable . Sounds hard? Nope. Let’s look at an example. Let’s say our hypothesis is that cold weather will let you flip a coin with more heads than tails. The independent variable is the temperature. The dependent variable is the number of heads or tails that show up. Our experiment could involve flipping a coin fifty times in different temperatures (outside, in a sauna, in room temperature) and seeing how many heads/tails we get.
One other important point – write down all the steps you take and the materials you use!! This will be in your final report and project board. Example – for our coin flipping experiment, we will have a coin (or more than one), a thermometer to keep track of the temperature in our environment. Take pictures of the flipping too!
Analyze Results – Make Conclusions
Analyzing means adding up our results and putting them into pretty pictures. Use charts and graphs whenever you can. In our last coin flipping example, you’d want to include bar charts of the number of heads and tails at different temperatures. If you’re doing some other type of experiment, take pictures during the different steps to document everything.
This is the fun part…. Now we get to see if we answered our question! Did the weather affect the coin flipping? Did eating cake help us do better on our test?? So exciting! Look through what the data tells you and try to answer your question. Your hypothesis may / may not be correct. It’s not important either way – the most important part is what you learned and the process. Check out these references for more help:
- How to make a chart or graph in Google Sheets
- How to make a chart in Excel
Presentation Time – Set Up Your Board, Practice Your Talk
Personally, the presentation is my favorite part! First, you get to show off all your hard work and look back at everything you did! Additionally, science fair rules should outline the specific sections that need to be in the report, and in the poster board – so, be like Emmett from Lego Movie and read the instructions. Here’s a loose overview of what you should include:
- Title – what is it called.
- Introduction / background – here’s why you’re doing it and helping the judges learn a bit about your project.
- Materials/Methods – what you used and the steps in your experiment. This is so someone else could repeat your experiment.
- Results – what was the outcome? How many heads/tails? Include pictures and graphs.
- Conclusions – was your hypothesis correct? What else would you like to investigate now? What went right and what went wrong?
- References – if you did research, where did you get your information from? What are your sources?
The written report will be very similar to the final presentation board. The board that you’ll prepare is usually a three-panel board set up like the picture shown below.
To prepare for the presentation, you and your partner should be able to talk about the following:
- why you did the experiment
- the hypothesis that was tested
- the data results
- the conclusions.
It’s totally OK to not know an answer. Just remember this is the fun part!
And that’s it! YOU DID IT!!
Science fair projects have been great opportunities for our kids to not only learn more about science, but to also be challenged and push themselves. Independent projects like these are usually a great learning opportunity. Has your child completed a science fair project that they are proud of? Include a pic in the comments – we love to share science!! Please also check out our STEMium Resources page for more science fair project tips and tricks .

Discover the Joy of Science: 16 Experiments Perfect for Elementary Students
When I am continuously going over worksheets or books with my elementary class, I notice my students’ long and bored faces, their eyes drifting away from the material. Because of this observation, I try to integrate at least one hands-on science experiment into my weekly schedule. This approach not only keeps the children entertained, engaged, and focused but also fuels their innate curiosity. The objective is to spice things up every once in a while to keep my classroom fun and the learning experience vibrant.
The future is dependent on humans who know how to use science to make sound decisions, innovate, and take part in cultural, political, and civic conversations. Understanding this, I felt a responsibility. With that being said, I wanted to help other teachers around the world learn how to introduce science in fun, practical, and interactive ways for their elementary-aged students. Therefore, I am sharing my ultimate list of 16 science experiments for elementary school in this article.
This is how experiments are held at Northridge Elementary School:
WOW! The 5th graders at Northridge Elementary School participated in our lesson NEWTON’S 2nd LAW OF MOTION. Their experiments helped them understand force, mass, and acceleration. https://t.co/IRMc0iv6RJ pic.twitter.com/a93gleNPnL — WPAFB EO Office (@wpafbeo) March 2, 2022
Bread Mold Experiment
Categories STEM Activities
We love classic science fair projects, which is why we have always wanted to try the classic bread mold experiment.
Although not as flashy as some of our other classic science fair projects, it was probably more educational than some others.
The students enjoyed seeing how long it took for mold to grow on various forms of bread. There is something really magical about those classic science experiments that have been done for generations! It’s fun to see each new generation learn something new each time they do the experiment.
Classic Bread Mold Experiment for Kids!
Follow along with these instructions to make your own version of the bread mould experiment!
Bread Mold Experiment Hypothesis Ideas
Kids should come up with their own hypothesis for the mold experiment. Have the children create a hypothesis something like this:
- Bread with preservatives will take longer to mold
- Bread in a sunny location will take longer to mold
- Warm bread will mold faster
- Wet bread will mold faster
- Bread will mold faster in the open air than in a plastic bag
Our experiment was simple. We placed bread in various conditions (we had dry dark, dry light, wet, open, and in a closed bag) and Monkey came up with a hypothesis for which piece of bread would mold first.
She predicted it would be the bread we placed in the paper bag in the pantry.
Mold Facts for Science Projects
When doing your bread mold science fair project, here are some fun mold facts for kids to include:
- Mold is a type of fungus.
- Mold grows in the shape or multicellular filaments called hyphae.
- Mold grows from spores that float in the air.
- There are thousands of types of mold, some good and some bad.
- A lot of cheese and antibiotics are created with a mold as a base.
- Mold is usually fuzzy.
- Mold is considered a single organism.
Bread Mold Experiment Materials
- Bread (fresh bread from a bakery will produce much faster results than bread with preservatives)
- Various bags
- A permanent marker to label each piece of bread

Bread Mold Science Fair Project Directions
Divide your bread into as many pieces as you want to test. We used around five pieces.
We only put water on one of our bread pieces, but for the best “scientific” results, you should put water on one piece in a dark place and one in a light place.
In all, we had:
- Bread in a plastic bag in the light
- Bread in a plastic bag in the dark
- Bread in a paper bag in the dark
- Bread on a paper plate with no bag
- Wet bread in a plastic bag
My kids thought the dry bread in the paper bag would mold first.
You can take this project further by measuring how much mold is on each piece of bread after a certain number of days.
We just wanted to see which bread piece would mold first, so we did not do any mold measuring.
Bread Mould Experiment Results
It took about two days for the first mold to show up- which was on the wet piece.
We waited weeks for any mold to show up on any of the other pieces, but it didn’t. This is why we recommend using fresh bread without preservatives.
We finally gave up on waiting for any more mold to grow and threw it out.
The kids were surprised that the wet bread grew mold first, but she thought it was interesting that mold grows faster in damp, warm conditions.

How to Make a Baking Soda Volcano
Step-By-Step Instructions for a Classic Science Fair Project
busypix / Getty Images
- Ph.D., Biomedical Sciences, University of Tennessee at Knoxville
- B.A., Physics and Mathematics, Hastings College
The baking soda and vinegar volcano is a classic science project that can help kids learn about chemical reactions and what happens when a volcano erupts . While it's obviously not the real thing, this kitchen equivalent is cool all the same! The baking soda volcano is also non-toxic, which adds to its appeal—and it only takes about 30 minutes to complete.
Did You Know?
- The cool red lava is the result of a chemical reaction between the baking soda and vinegar.
- In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.
- As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until—thanks to the detergent—the gas bubbles out of the mouth of the volcano.
Volcano Science Project Materials
- 6 cups flour
- 2 cups salt
- 4 tablespoons cooking oil
- plastic soda bottle
- dishwashing detergent
- food coloring
- baking dish or another pan
- 2 tablespoons baking soda
Make the Chemical Volcano
- Start by making the cone of your baking soda volcano by mixing 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (add more water if needed).
- Stand the soda bottle in the baking pan and mold the dough around it to form a volcano shape. Be sure not to cover the hole or drop dough inside the bottle.
- Fill the bottle most of the way full with warm water and a bit of red food coloring. (You can do this prior to sculpting the cone as long as you don't take so long that the water gets cold.)
- Add 6 drops of detergent to the contents of the bottle. The detergent helps trap bubbles produced by the chemical reaction so you get better lava.
- Add 2 tablespoons baking soda to the liquid in the bottle.
- Slowly pour vinegar into the bottle, and then watch out...It's eruption time!
Experiment With the Volcano
While it's fine for young explorers to tackle a simple model volcano, if you want to make the volcano a better science project, you'll want to add the scientific method . Here are some ideas for different ways to experiment with a baking soda volcano:
- Make a prediction about what happens if you change the amount of baking soda or vinegar. Record and analyze the effect, if any.
- Can you think of ways to change the volcano to make the eruption go higher or last longer? This might involve changing the chemicals or the shape of the volcano. It helps to record numerical data, such as the volume of liquid, the height of the "lava," or the duration of the eruption.
- Does it affect your volcano if you use a different kind of chemical to color the volcano? You could use tempera paint powder.
- Try using tonic water instead of regular water to get a volcano that glows under black light.
- What happens if you substitute other acids instead of vinegar or other bases instead of baking soda? (Examples of acids include lemon juice or ketchup; examples of bases include laundry detergent and household ammonia.) Use caution if you decide to substitute chemicals because some mixtures can be dangerous and may produce hazardous gasses. Never experiment with bleach or bathroom cleaners.
- Adding a bit of food coloring will result in red-orange lava! Orange seems to work best. Add some red, yellow, and even purple, for a bright display.

Now is the time to reminisce about the moments that made the school year special and to create lasting memories that students will carry with them to the next grade. Teachers, you can utilize these end-of-year activities and ideas to celebrate with young learners on the final day of school. Many of the elementary end-of-year activities shared are available in both English and Spanish.
The Best End-of-Year Learning Activities for Elementary Students
Hold a picture book show and tell.
For students who don’t have a book from home or the local library to share, encourage them to select a favorite from the classroom library or share one of the following children’s books with the class:
- Catch Him Just for Fun ( Atrápalo solo por diversión )
- Hair ( Pelo )
- Jumbled ( Enredado )
- Magnifying Glass ( La Lupa )
- Opposites ( Opuestos )
Go on an outdoor walk
As students get closer to the end of the year, it can be hard to keep their attention on lessons. If the weather permits during the last weeks of school, take learning beyond the confines of the classroom with an outdoor science lesson.
Try a walk around the school grounds to foster curiosity and solidify concepts students are learning in science class. Use this scavenger hunt (or make your own list based on local sights) to help your learners pay attention to their surroundings. If you’re teaching students about cloud types, for example, you could go on a walk to identify the different kinds of clouds they see outside.
Plan a community service project
Finish off the year with an activity that builds mindset skills by organizing a service project! Whether it’s cleaning up a local park, holding a donation drive, or volunteering at a nearby organization as a field trip, students can learn the value of empathy and citizenship .
Plan an end-of-year STEM challenge
Hands-on STEM challenges are a great way to practice team building skills and end the year with a learning refresher. Assign students to groups and give them a STEM project to solve together connected to a subject you learned over the year. If you taught your students about making a hypothesis, for example, you could use this Fruit Float challenge .
After all of the groups have completed the challenge, lead a class discussion about their results and how they connect to your science or math lessons from earlier in the year.
Start a summer journal
Summer journals can provide students with a creative outlet and a way to practice communication skills over the break. If your class budget allows, give your students a blank journal or notebook. Encourage them to personalize it with fun drawings or stickers.
Along with the journal, assign them a few prompts to ignite their writing over the coming months, like favorite summer moments, aspirations, or reflections on the past school year. This list of journal prompts for children is a great starting point.
If the class budget doesn’t allow for providing each student with a blank journal or notebook, you can encourage students to create their own summer journals using materials they already have at home. They can use plain paper stapled or bound together to create their journal, or repurpose an old notebook. You can also suggest using digital platforms or apps for journaling if students have access to devices.
The Best End-of-Year Reflection Activities for Elementary Students
Make memory collages.
Help students capture their favorite class memories by making a collage of their favorite moments from the school year. Start with a class discussion for students to share their favorite moments from the past year. Then, hand out magazines, scrapbook paper, and art supplies to make a collage reflecting these moments. Finally, allow students the opportunity to share their collages with the class if they feel comfortable.
Create an end-of-year art gallery
In the last week of school, have students share their art project with the class. As students present their projects, they will also gain an appreciation for their classmates’ talents.
For a stress-free end-of-year art activity that promotes mindfulness , consider hosting a coloring break with downloadable pages featuring Waterford characters:
- Group Project
- Nature Walk
Build a time capsule
A time capsule filled with mementos and messages can help students reflect on their current selves and how they have changed over the school year. Give each child a small container and have them fill it with drawings, photos, handwritten notes, and other keepsakes. Anything that fits in the container and holds meaning to your student will make a great addition!
Send the time capsules home with families along with the instructions to open them after a set time—anywhere from the end of summer to several years from now. That way, in the years to follow, each item the time capsule holds will serve as a snapshot of their favorite memories from their year in class.
Hold a class awards ceremony
Celebrate the unique talents and contributions of each student with an end-of-year awards ceremony . Whether it’s for “Most Creative Artist” or “Best Team Player,” ensure every student receives recognition for the gifts they bring to the classroom. This activity can boost self-esteem at the end of the year, affirming each student’s value within your school’s community.
Encourage reflection and goal setting
Give students time to reflect on the past school year and set goals for the future. Encourage them to write reflection letters addressed to their future selves, prompting them to share their achievements and outline plans for the summer and the upcoming school year.
This Goal Setting ( Estableciendo metas ) end-of-year worksheet can be a great way for students to set goals and break down the steps they’ll take to achieve them.
As the school year draws to a close, cherish the memories your class has created together and end the year with activities that foster learning and reflection.
