All we see is light. Your face in the mirror, the trees on your street, that donut in the bakery window—you can see them because light bounces off of them and enters your eyes. Our eyes are designed to detect light and analyze the information it carries about the world around us.
In the hands-on activities that follow, you’ll investigate some of the amazing properties of light. You can bend light (called refraction when it passes through lenses or diffraction when it bends around an edge or passes through a slit), bounce light around using mirrors (also known as reflection), and explore the multicolored potential of shadows.
It’s all around us, and while you may not be able to hold it in your hands, seeing is believing—light is pretty amazing stuff.
