Do Video Game Players Have Faster Reaction Times Than Non-Players?

Science Fair Project Idea

Scientific Method

When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

Can You Walk the Talk? Exploring Distractions and the Timed Up and Go Test

Science Fair Project Idea

Scientific Method

Test your multitasking skills with the Timed Up and Go (TUG) Test! In this challenge, you'll evaluate a person’s functional mobility when they're focused versus when they're distracted. Can your brain handle walking and talking at the same time? Let’s find out! Read more

Build a Helping Hand

Science Fair Project Idea

Engineering Design Process

The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial… Read more

Motor Imagery Visualization's Impact on Fine Motor Skills for Space Flight

Science Fair Project Idea

Scientific Method

In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more

Make a Communication Aid To Help People Show Their Feelings

Science Fair Project Idea

Engineering Design Process

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. Read more

Iron-Rich Foods: How to Get the Most Out of Them

Science Fair Project Idea

Scientific Method

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond flour—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Make a Medical Alert Fall Detector

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… Read more

How Fast Is Your Reaction Time?

Science Fair Project Idea

Scientific Method

Many sports skills require quick reaction times: think of hitting a 95-mph fastball, returning a 100-mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate… Read more
