Here is a comprehensive package in which middle schoolers learn about types of seismic waves, triangulation, and tectonic plate boundaries. Complete vocabulary, colorful maps, and a worksheet are included via links on the webpage. You will need to have some Slinky® spring toys on hand to demonstrate P and S waves, and a way to project the accompanying maps. A whole-class activity involves learners lining up with shoulders touching, and having them act out the wave movements.
