Students recognize differences in the size, shape, texture, and color of different rocks. In this rocks lesson plan, students also learn and repeat back how a volcano erupts and make one out of a toilet paper tube.

Second graders read "Sylvester and the Magic Pebble" by iam Steig and practice describing rocks using different physical properties. They make observations and develop and describe categories such as texture, color, density, hardness, etc.

Students classify different types of rocks. In this earth science lesson, students test different rock samples and construct a chart to record observations. They create a concept map that answers essential questions.
