In this activity, learners explore the engineering and principles behind working elevators.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

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.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.
