Plate Tectonics and Boundaries

Miss Holly introduces a STEM activity using graham crackers to demonstrate plate tectonics. She explains Earth's layers and how plate tectonics work. The activity involves creating transform, divergent, and convergent boundaries with graham crackers and cool whip. Each boundary type is demonstrated, showing how they cause earthquakes, seafloor spreading, and mountain formation. The video concludes with encouragement to try the activity at home.
