Landform experiment

Today we did a great experiment with Miss Henigan!! We wanted to see what would happen to the soil on a hill when it rains. Our soil just had rocks and dried leaves on it. No plants or grass growing in it so the soil should not stay on the hill. Sure enought the soil ran down the hill with the water. Tomorrow we are going to see what happens to the soil if grass is growing on the hill. The goal of these two experiments is for the children to notice that roots from grass, plants or trees keep the soil from eroding when it rains on a hill.
