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.

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.

Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home.

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?

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world…
