Are You Left or Right Sided?

Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain.

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

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 the limits of peripheral vision and learn how to understand your results based on the anatomy of the human eye.   Read more...

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...
