Review middle school Earth science on rocks, the rock cycle, plate tectonics, and Earth's layers with definitions, processes, and examples. Built for Grades 6-8. 25 ready-to-play clues, no prep needed. This is a Grades 6–8 Science review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Rock Cycle, Rock Types, Minerals & Tests, Plate Boundaries, Earth's Layers.
