Fourth graders make models of igneous, metamorphic, and sedimentary rocks out of different types of candy and cookies.

Students make sequential patterns by using ants and following the model. They identify different parts of an ant by matching the picture to the word name. Pupils identify the ant's life cycle by creating a chart using pictures.
