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

How Protective is Your Helmet?

Science Fair Project Idea

Scientific Method

Every time you hop on your bike or gear up for football or baseball practice, your helmet is your first line of defense. Whether you’re coasting downhill or tackling on the gridiron, impacts happen — and they can cause more than just bumps and bruises. Scientists tell us that forceful hits to the head can lead to concussions or even more serious brain injury over time. Correct helmet design, proper fit, and good cushioning all help reduce those risks. For example, bicycling is one… Read more

Have you ever wondered how strong hair is? When we talk about our hair we usually discuss color, length or texture. But what about hair strength? If you look at a strand of hair, it looks like a very thin string. In fact, it is on average only about 0.1 millimeters thick. It doesn't seem like such a thin string could withstand much force. How much weight do you think a single strand of hair can carry? In this activity you will put a hair to the test and find out. You might be surprised by your… 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

Now You See It, Now You Don't! Test Your Peripheral Vision

Science Fair Project Idea

Scientific Method

Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… Read more
