Lesson Overview

Students will:

• Make observations about their rock samples
• Categorize rock sample cards, and then match them to their rock names based on observations and descriptions.
• Debrief the matching game, learn vocabulary, and match rock samples to the game board.
• Watch their instructor demonstrate the Rock Cycle using crayon shavings and a lighter

Lesson Objectives

Students will be able to:

• Explain how sedimentary, igneous, and metamorphic rocks form
• Discuss how rocks change from one form to another over geologic time

Disciplinary Core Idea (DCI)

ESS2 Earth’s Systems – ESS2.A Earth’s Materials and Systems

• (3rd-5th) Four major Earth systems interact. Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, organisms, and gravity break rocks, soils, and sediments into smaller pieces and move them around.

Science & Engineering Practice (SEP) 

• (3rd-5th) Constructing Explanations – Identify the evidence that supports particular points in an explanation.
• (3rd-5th) Obtaining, Evaluating, and Communicating Information – Read and comprehend grade-appropriate complex texts and/or other reliable media to summarize and obtain scientific and technical ideas and describe how they are supported by evidence. 

Crosscutting Concept (CCC)

• (3rd-5th) Patterns – Patterns can be used as evidence to support an explanation
• (3rd-5th) Structure and Function – Different materials have different substructures, which can sometimes be observed
