Erosion

How do water, wind, gravity, and temperature play a role in erosion? In four interactive lessons, students will wear safety goggles to demonstrate the forces of wind and the movement of water in the transportation and deposition of weathered rock. Distinction between mechanical and chemical weathering will be made through a lab activity involving water, salt water, vinegar, and chalk. If a freezer is available, the students will be able to experience how freezing and thawing is an active part of weathering. Using a set of plastic bins and sand, students will create sand dunes, build rivers, model landslides, and demonstrate earthquakes. All of these lessons involve the use of water, therefore a protective tarp will be provided for each small group, but working outdoors is highly encouraged. A lesson plan timeline averages 50 minutes, but can easily be broken into smaller sessions. All lessons are organized to enable the teacher to maximize contact time with the students and minimize preparation time.
