Have you ever seen a cat slowly move its head and whiskers into a small space before crawling through it? They’re using their sense of touch to see if they can fit into the space! In this science experiment, you’ll test how cats use their sense of touch to move through the world by using a maze to determine if they prefer big or small spaces.

Your heart starts beating before you are born and keeps right on going through your whole life. Over an average lifetime, the human heart beats more than 2.5 billion times. Keeping your heart healthy means eating right, not smoking, and getting regular exercise. Which of your favorite physical activities give your heart the best workout and help keep it fit? In this science project, you will use a smartphone equipped with a sensor app to visualize your heart rate and find out which…

"Paper circuits" are a fun way to mix electronics and art by adding lights directly to a painting or drawing. These lights need a battery to power them, and typically you would use wires to connect them. In paper circuits, though, many materials can be substituted as "wire," including special types of paint, ink, and even aluminum foil. There are also different options for what type of battery you can use. Which materials do you think will work best? Try this project to find out!

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and…

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home.

Have you ever tried to communicate with a baby or toddler who cannot talk yet? What about another kid or an adult who cannot speak due to a medical condition? There are many ways we can communicate without speaking, like writing or using sign language. We can also use technology to help make it easier to communicate. In this project you will program your own communication aid to help someone who cannot speak show their emotions or simple messages.

Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help…

Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time — you may have been too busy trying to grab the phone! But you probably wanted to find out just how hard it hit the ground afterwards. We know that gravity forces an object to fall, but how does this affect how quickly something falls and how hard it hits the ground? For example, did the phone move faster…

You're probably familiar with sauerkraut, a German dish of cabbage that is fermented in a brine made of its own juice and salt. Have you heard of another cabbage dish, called kimchi? Kimchi is a traditional fermented cabbage dish from Korea. Koreans eat kimchi year round, enjoying its spicy taste and the fact that it contains loads of vitamins B and C. In this cooking and food science fair project, you will make kimchi from scratch and investigate changes in pH and glucose as the kimchi…
