Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

This science fair project idea explores whether white light can be separated into different colors.

What happens when eyes see something that the brain knows cannot be true? In this science activity, the brain has to "fudge" it when interpreting what you see.

This science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

Learn about magnifying glasses, concave lenses and inverted images by sending rays of light through a magnifying glass in this cool science fair project!
