Rock Cycle Lab Activity

The investigations in this kit turn the task of learning rock types and rock cycles processes into something memorable for elementary and middle school students.

In this first investigation, students examine sedimentary, metamorphic, and igneous rocks. They then model some rock cycle processes while making their own sedimentary rock model form a mixture of sand and an Epsom salt solution. In the second investigation, students press crayon savings between heated blocks to model how heat and pressure changes rocks from sedimentary to metamorphic rockc. In the last investigation, students create igneous rock models from a "magma solution". They will also observe how crystal size is affected by time. This activity allows students to explore Framework Science Standards ESS1 and ESS2.

This kit has been aligned with all published National Standards. Pre- and Post-laboratory assessments and vocabulary words all target specific Science and Engineering Practices and common core standards. The teacher guide also contains specific "Did You Know" concepts that link the real world with the scientific standards explored. A student copymaster is included. This kit includes materials for a class of 30 students.
