In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.
