In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

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

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

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

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.
