Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
