Students will learn the differences between binoculars and monoculars and how to use them. Binoculars and monoculars from the Field Kit, posters, an inflated balloon, magic marker. One class period. Peregrine falcons use both of the eyes to focus in on their dinner.
Stereoscopic vision is another name for using both eyes to focus on the same object.
And, just like you would adjust the focus of your binoculars when you zoom in to take a closer look, Peregrine falcons eyeballs change shape when they are zooming in at almost 200 miles per hour after their prey. Magnification and light-gathering Power Eagles can see their prey almost 2 miles away from them. They need to know if the prey they see are sick, injured or in a position they could sneak up on them. The lens in their eyes has high magnification powers, just like the binoculars the Coast Guard use to read ship names very far away. Owls on the other hand, find their prey in the dark.
