In this activity students will build, and observe with, simple refractory telescope providing an interactive introduction to light, lenses and refraction. Then walk away from the lens, perhaps as far as a meter, until you see Step 3: Setup. your friend hold the paper at the focal point. Have The magnifying glass will be the eyepiece. I made one of these which I take to classes to demonstrate what a refractor is, to young children.
