Why Lesson Planet?
Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich. If you have learners with peanut allergies, make sure to substitute cream cheese or sunflower butter for the peanut butter layer. In the second activity, a timeline of geologic history is created.
