Echolocation

We are doing Apologia swimming creatures for science and we are on lesson 2. We have been reading about whales and their differences and what they do and where they live. Today we came across our first Try This part which is a little fun experiment to do. It had to do with echolocation.

What you do is roll up two pieces of cardstock in the shape of a funnel and tape it up. Then you talk thru one while you listen from the other one. We talked toward a wall and the other listened and heard what the other said. It was fun and they all got into the fun of saying crazy things to each other.
