One of the afternoon children had a question. Why does all of the water in rivers not sink into the ground? We decided to help him see the answer by making it a concete experience!
We made a small model of a river by gluing and taping styrofoam pieces to make different elevations into a plastic tray. We then put a layer of modeling clay over all of it.
We then poured water with some blue food coloring in it on the top and watched how the water flowed quickly down. We talked about where water comes from that forms rivers.
In addition to the hands on experiment, we made our own parts of a river booklet to take home.
