Science Fair Project Idea
This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

Science Fair Project Idea
In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available. Read more
Science Fair Project Idea
You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Read more
Science Fair Project Idea
Have you ever heard the phrase, "Seeing is believing"? Well, it is more accurate than you might think! In this science project, you can investigate the phenomenon of apparent motion by making your own flip-book animations Read more
Science Fair Project Idea
Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words.

Science Fair Project Idea
Have you ever wondered if some shapes have certain "sounds" to people, even if they have different native languages? For example, does everyone match certain physical characteristics, like sharpness or roundness, with certain sounds? Are there certain human sounds with meanings that can cross the language barrier? In this science project you will investigate this by testing the Bouba-Kiki Effect—will it turn out that abstract visual properties can be linked to sound? Read more

Science Fair Project Idea
When you play Connect 4, what strategies do you use to increase your chances of winning? In this project, you will explore how artificial intelligence can make decisions in two-player games such as Connect 4. This project requires little to no coding skill. Instead, you will need patience and an open mind. Why not give it a try yourself? Read more
Science Fair Project Idea
You've probably observed from your own personal experiences that some actions are contagious. Yawning is a great example. When one person in a room yawns, several other people usually do, too. Coughing, clearing your throat, these are other actions that often seem contagious. But what about smiling? Have you ever walked down the street and had a random stranger smile at you? Did it make you happy? Did you smile back? In this science fair project, you'll investigate whether smiling is… Read more
Science Fair Project Idea
Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more
Science Fair Project Idea
Have you ever flown a drone? Did you find it easy the first time you tried? In this project, you will fly a drone through an obstacle course and measure how practice changes your performance. Will practice help you finish the course in less time? Try it out! Read more
Science Fair Project Idea
What is your favorite color and why? Do you think that simple tasks might be biased by your preferences? Find out in this science project if your color preferences will bias your fine motor skills when doing quick, repetitive tasks. Read more
Science Fair Project Idea
Do you like to read? Did you know that most people read without even thinking about it? Find out in this experiment how a simple reading/color test called the Stroop Effect can show you how your brain works. Read more
