How to Do a Great Elementary Science Fair Project and Board Layout
Help! My kids have to do a science project! Parents panic and wonder what to do, and sometimes, schools don't provide very clear guidelines on what is expected.
As an educator and a parent, I've written these instructions to help. My five kids started doing science projects in elementary school, where I was a Science Fair Coordinator for several years. My four older children have won 1st or 2nd place at the Regional Science Fair. My son won 2nd at State as a 7th grader. Along the way, I've learned a lot about what goes into a good science project and also learned how to make this an enjoyable process for both parents and kids.

Science Fair 101: How Do You Do a Science Fair Project?
A science fair project is done to investigate something about the natural world—whether it is chemistry, biology, physics, psychology, or another area of science. Usually, a student starts with an interest in some topic. Next, they need to decide on a question that they could devise a test to answer.
Here are the eight basic steps to building a science project:
- Choose a topic (e.g. chemical solutions)
- Ask a question (e.g. Which solutions remove stains fastest?)
- Form a hypothesis, or a proposed explanation (e.g. Bleach removes stains fastest because it is a strong base.)
- Design a procedure to test that question (e.g. Compare bleach with other solutions, such as ordinary detergent, vinegar, hydrogen peroxide, etc.)
- Gather your materials
- Perform the experiment and record the results (e.g. Bleach was fastest, but all the other solutions had roughly equal stain-removing power.)
- Write a conclusion by comparing the results to your hypothesis. (e.g. The results were as I expected, but to my surprise, none of the other solutions were better than the other.)
- Discuss what went right and/or what went wrong. Suggest ideas for future experiments, or any changes you would make if you were to repeat the experiment. (e.g. In the future, I will test the same solutions on different types of stains or different fabrics.)
Any question that can be tested by a student will make a good project. So you might want to ask your kids if they have a question they are interested in exploring. Or you might want to have them look at the list of questions below to come up with some ideas.
As students do their experiment, they will take notes so that they can prepare a poster that describes their project. This poster will allow someone else to understand what did and what they learned. By the way, professional scientists share their work in exactly the same way at scientific conferences!

Simple Elementary Science Project Ideas
How Do You Make a Science Fair Board?
How do you prepare a poster? This is the question I get most often as a science fair coordinator. I encourage parents to use the same basic format that real scientists use on their posters (for our school fair, I try to bring one of my husband's biology research posters to show as an example).
At conferences, scientists show their work through giving talks with a slideshow or by standing next to a poster and describes their work, just as kids do with theirs. So this experience is one that will teach them how the process really works.
Generally, displays for school science fairs are trifold, which means that they are folded on either side so that they can stand up for easier viewing. In most fairs, your board can be up to 36 inches wide and 14 inches tall. You can find the trifold boards available at most office supply stores and at some Walmarts, grocery stores, drug stores, and craft stores.
You can also make your own board by layering a large poster board over a piece of cardboard. If you make your own board, you should probably make three separate pieces and use duct tape to hold them together so they will bend.
Board Format and Layout
A general guide for what elements the judges will be looking for is the following:
- Title (This could be your question—or something to make your audience interested in your topic).
- Question (State your question clearly and explain how you got interested in this question).
- Hypothesis (This is your guess of the answer to your question. Tell why you think this will be the result.)
- Procedures (the plan for testing your question and why you chose this plan).
- Materials and Equipment (a list of what you will need for your experiment).
- Results and Data (Your description of what happened when you did your experiment. You should include any graphs or charts which help show your results).
- Conclusion (This is where you explain what happened, and tell whether your guess was correct or not. This is also where you can explain why you got the results you did. If you did your experiment again, would you change anything?)
- Resources (Who helped you? What books or websites gave you ideas?)
- Personal Information: Your name, grade, and teacher.
These elements can usually be organized as you please, as long as they follow a logical order. Some schools or fairs may have guidelines on what they expect, so it wouldn't hurt to ask ahead of time.
A typical layout is as follows: the title is centered at the top in large, readable font to catch people's attention. The question, hypothesis, materials, and procedures are usually on the left panel, while the data, conclusion, resources, and personal information are on the right panel. The center is reserved for pictures of your experiment and your main results.
Tips for Succeeding at Science Fairs
- Journal as You Go: As you are working through each stage of your information, be sure you keep a notebook or journal of your process. You can jot down anything you do, including notes you take in finding your topic as well as charts you keep while doing your experiment. Be sure you include all of the parts listed below (like hypothesis, materials etc.). Many science fairs want you to show your journal as part of your project. Real scientists need to keep a bound and dated journal written in pen so that they can prove they really did the work and explain the steps they completed.
- Type Your Results for Your Board: It is a lot easier for you to type your information and titles for each part of your report on a separate piece of paper and then paste or tape this paper onto your poster board rather than printing on the board itself. Often, it is easier to do this on a computer. You can use color, bold fonts, and clip art, but remember to keep your poster very readable with the letters sized so that they can be read by a person standing a couple of feet away. Print it out and hold it up about a yard away. Can you read it? You don't want the judge to miss something because they can't see what you wrote. Don't make the font hard to read either. Fonts like Euro-style, Ariel, or Times New Roman are good to use. Make sure each of your topics has a bold headline (Hypothesis, Results etc.)
- Keep Your Camera on Hand: Your poster will be more interesting if you include some pictures you take while doing your experiment or use clip art pictures or pictures you draw. I always have my camera out when the kids are doing the experiment. I take a picture of all the materials they use as well as pictures of them doing the experiment. Keep a camera on hand to show the process. Take a picture of all the materials, for instance. Take pictures at each stage of the process and take pictures at the end. Print the pictures out to use on your board.
- Use Color!: You can choose a colorful board if it is allowed at your school. You can also include color by putting your printed work on construction paper, colored card stock or scrapbook paper. Your title can be cut out letters, or printed out large-font writing. Some students use stickers, colored paper or cut out letters to make their poster more attractive. If the rules from your school allow it, you can also bring some of the examples from your experiment to put in front of your poster if that is appropriate. Sometimes, students also use bulletin board edging around the borders of their posters.
- How to Put it All Together: For best results, lay out everything on your board without gluing or taping down first. Generally, you will put the title at the top; the hypothesis, materials and procedures on the right side; the results and data in the middle; and the conclusion, resources and personal information on the right side. Of course, you will need to adjust this depending on the size of each section. Attach the printed information onto the colored paper with glue sticks or glue dots (glue dots can be found in hobby stores in the scrapbooking aisle). Glue dots stick the best. White glue can be used, but it may make the paper wrinkle, and it may not be possible to change anything. Glue dots and glue sticks can often be taken off and changed around more easily.
- Maximize Your Space: You may need to play around with it, but you want the fonts and pictures to be as large as possible. It's always easier on the eyes to be able to read and see everything from a few feet back.
- How About Parent Help? Students should do as much of the work as possible at their age level. Check the requirements for your school, but generally, the information on the poster can be hand-written or typed. For most schools (and even our regional and state science fair in Texas), it is alright for parents to type up their children’s notes or oral explanations of their projects; however, they should be sure that the child tells them what to write.
- Practice Talking About Your Project: It is important to make sure that your child can explain everything they did to the judges. The poster is only half of the presentation. The other half is the child doing the actual talking. Although they did the all the critical thinking and hard work, it may not be so easy explaining it to someone else, so practicing a brief presentation is recommended. Usually, I have my kids practice explaining what they did to me and to their brother and sisters. The presentation should only be about 8-10 minutes with time for questions.
How Does Judging Work?
Elementary School Level
A lot of work goes into science fair projects, and all students deserve to have that work rewarded. Our elementary school science fair does not award 1st, 2nd or 3rd. Instead, each child is judged according to what is best about their project (thoughtful process, good scientific thinking, etc.) and awarded a blue ribbon reflecting their achievement as well as a sheet of comments from the judge. The goal at this level is to pique students' interest in science and to teach students the scientific process, critical thinking, hands-on learning, and presentation skills.
Middle and High School Level
At the middle and high school level, fairs are a little more competitive, and students are judged based on their scientific thinking, reasoning, and possibly their ability to relate their project to a bigger picture. In our district, students are judged at school and can also go on to regional and state fairs. Following the procedures I've described above, both of my older children won at their school and regional every year they have competed. One year, my son also won 2nd at state. If you follow my steps, your project should be among the best at your school too.
How to Prepare for the Science Fair Judge
Everyone involved in a science fair can tell you that judging is a lot of work. The judges do that work because they believe science fair is a way of encouraging kids to go into STEM (science, technology, engineering, and math) careers. While judges want to evaluate the students, they also generally want to encourage them and give them a chance to explain what they have done and what they have learned. The best way to prepare for the judge is to practice telling people about your project.
A parent or friend could help you practice by asking these sorts of questions:
- How did you get interested in this topic?
- What question did you ask?
- What experiment did you do to try to answer your question?
- What did you think was going to happen in your experiment?
- What happened? Were you surprised by the results?
- If you were going to do the experiment again, would you change anything?
- What was most interesting to you about your project?
- What part did you do? What did you get help with?
- What did you learn?
Science Project Website Reviews
There are many websites available to help students and parents do science projects. You can also get one of the books I've suggested. Here is a short review of some of the best science fair websites
Science Buddies: Science Buddies is an excellent site to go to for help with your project. Their “topic selection wizard” allows you to answer a series of questions to help you narrow down projects your child would enjoy. This site also rates projects by grade level and provides background scientific information as well as complete instructions for how to do the experiment.
All Science Fair Projects: All-Science Fair Projects offers a collection of ideas taken from other websites. You can browse by interest and ability level. Because many of the contributions come from third-party websites, the quality of the information can vary, but if you have an area you are interested in, you might want to check out the projects on this site for ideas.
Home Training Tools: Science Fair: This page on the Home Training Tools site offers some excellent and easy science fair projects with clear instructions and illustrations. Note: this is a company which does sell items for projects but most of the instructions on this page can be done with materials found at home or at the supermarket.
The Discovery Education Center Science Fair Central: The Discovery Education center gives many ideas for easy science fair questions for elementary students. It also guides students through the process of creating their project. Unlike some of the other sites, this does not give full instructions for projects, but questions like, “Which type of paper makes the best paper airplane?” are fairly easy for students to do on their own.
Worth the Effort?
Participating in Science Fair is a great experience for kids, but it can be a lot of work for everyone. Is it worth it? Watching our children go through the process from kindergarten to high school, my husband and I are sure it is. Remember that the very best jobs are in the STEM (science, technology, engineering, and math) areas and that doing a science project can encourage your kids to go on to a career in those areas. Moreover, there are a lot of scholarships available for kids who go in that direction
So take a deep breath and enjoy the adventure of learning about science with your kids. Taking time to encourage them in this project can be well worth the effort. Have fun!

Questions & Answers
What kind of pictures do you include in your poster?
Usually the best pictures are either ones which show some part of the experiment, or pictures showing you doing the experiment. For younger children, it can be a good idea for them to draw what they see as part of their data. That is an especially good idea for K-1st-grade students. That way they can participate in the poster and feel like it is their work, even if they cannot write up the project by themselves.Helpful 2
How do I organize my poster?
The best way to organize is to use the format provided by your teacher. Usually this means you do it in this order:
Sometimes there are other parts that an instructor will ask you to provide. Be sure to ask them what they want.Helpful 16
How do you make a bar graph?
You can make a good bar graph by using a ruler and some graph paper. Use different colors for each of the bars. The graph paper squares will help you make straight lines.Helpful 10
Is the background investigation important?
One thing you will need to think about as you put your board together is how much space you will allocate for the different aspects of your project. You want your board to be easy for a judge or someone else to read, so the font needs to be big enough that someone doesn't have to squint and can scan easily. That also means that things like the background investigation needs to be considered carefully. If the information is meaningful, you need to include it. For example, you might want to add background research or thinking if it:
1. Explains why you chose this project or the method.
2. Gives information that someone else needs to know which explains the science behind your project.
3. Explains the importance of your science project to a real-life product, problem, or situation.
The short answer is that the background research is essential for you to design your project carefully, and you will need to have that information in your notebook. However, you don't need to put it on your board unless the person looking at your experiment needs to know it to understand or appreciate what you have done.Helpful 6
