Mystery Marine Debris

Bats don't see that well, but they're not "blind as bats" either. How do they hunt in the dark? They use a technique called echolocation.

People have devised a similar method to see and find things in the dark, like submarines and fishes that lurk under water.

You and your classmates are going to act like bats and use echolocation to see the shape ground in the dark. Topography is a scientist's term for the shape of the Earth's surface with respect to elevation.

Will you figure out wherer you are without being able to see? Surprise discoveries await!
