- I liked the model with sand the best because we got to move it around and make it rain.
- Water affects the land because if the water overflows, it will erode the land. The land affects the water because if there is less land, the water will be deeper.
- I enjoyed the experiments in class where we made a hill and added water by rain or by river and collected runoff. I think we should do the third one at Teatown, because it will be fun doing it on a bigger model.
