In this lab, students will create different landforms and discover how they are changed through different forces of erosion. I use this as a whole group lab, and we talk about what we could use to model wind, rain, and a river. This lab could easily be adapted to small group or independent. I have included two different formats. The first works better with a whole group, and the second works better with small groups or independent learning.
Materials: Fan, sand, safety goggles, eyedropper, water, soil, paper plate, and stream table (or use a flat pan with a hole in the side and a straw to direct the water)
