JoinTake a Tumble: Weathering and Erosion Using a Rock Tumbler
The subtle effects of weathering and erosion are difficult to convey to students. However, through this activity, students can use a rock tumbler to gain a personal and scientific perspective on weather and erosion. Students have the opportunity to demonstrate their understanding of these concepts and work with geologic materials as they make predictions and measurements, record data, and do simple calculations (McKnight 1989).
