Curated OER
Sandwich Stratigraphy
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....
Curated OER
Earth Materials - Geology and Plate Tectonics
Not going into depth on any one topic, this Earth science presentation skims the crust. It touches on the materials that construct the crust and then moves into plate tectonics. This is a useful and colorful note-taking guide for your...
Curated OER
Mountains "Fold, Fault, Erupt, and Erode"
Fifth graders conduct an experiment to demonstrate the folding and rippling of rock to form a mountain. They identify mountain chains on a map, participate in the demonstrations, and define folding fault block, igneous eruptions, igneous...
Curated OER
Edible Rock Layers
Learners use edible food items to conduct an experiment that simulates the movement, folding, and faulting of rock strata like sandstone, siltstone, limestone, and shale. Students then get to eat the experiment when completed.
