Fourth-grade students are learning about the Earth's features by testing the effects of rain on the earth’s surface and the forces that cause landforms to grow. In the experiment, they created three mounds of soil, one large, one medium in size, and one small. They poured equal amounts of water over each of the soil piles to investigate how rain affects each of these landforms.

They also drew physical maps with legends to indicate different types of hills, valleys and other landforms. They are learning how maps can change over time, as Earth’s features change from weathering and erosion of Earth's surface.
