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

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

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

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

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.
