In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.
