How do you make a model of a rock? How do the minerals go together? Making models is a high level scientific practice. In this lesson, students make a physical model of the igneous rock, granite with a paper puzzle, compare their model with the real granite rock, and design a better model. Afterwards, there is a recipe for fudge for them to make a new model of the igneous rock basalt. Teacher instructions, scoring rubric, recording page, and a writing page are included in this lesson packet.
This lesson is in the green book Rising to the Challenge of the National Science Education Standards, also sold on this website. This is lesson eight of nine process skill lessons on rocks that will also be available for purchase as a bundle.
