Learners take on the role of environmental engineers as they design water filters.

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

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

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

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