In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
