This lab sheet walks grades 4-7 homeschoolers through a seven-step process for modeling how Earth’s tectonic plates carry continents across the asthenosphere over millions of years. Students flatten a clay base layer representing the asthenosphere, cut out plate-shaped pieces in a second color, add smaller continent shapes on top, mark positions with a marker, then physically push the plates in different directions and record what happens. The observation section asks them to sketch or describe the before and after positions, and three reflection questions prompt deeper thinking about how the model compares to real geological movement.

This model of continental drift with clay fits naturally into a plate tectonics unit study and works especially well following a lesson on Pangaea, since the sheet opens with a brief explanation of the supercontinent concept. Completing it gives your student a concrete demonstration of how colliding, separating, and sliding plates produce the continental arrangement we see on maps today, connecting abstract geological timescales to something they can observe in a single session.
