Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this activity, learners explore accuracy and precision.

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