We just completed an experiment on weathering and erosion, using dirt, sand, and gravel with water, wind, and ice. We conducted research first on some major Earth changes, including avalanches, landslides, earthquakes, and volcanoes. Students discusses how those major changes were represented in our experiment. We did the wind experiment first and recorded what we observed happened. Next we added the ice and last the water. We saw the most change when the water was added. Students documented their observations in their science journals/notebooks.
