Why Lesson Planet?
Here is a geology instructional activity that is sure to get your charges excited. It's all about the process of weathering of rocks. Learners study natural events that can cause rocks to break apart. Some of these events are: ice wedging, plant wedging, abrasion, and the effects of water. A terrific hands-on experiment/activity is aptly described, and a very good final review worksheet is embedded in the plan.
