In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners investigate the history and development of agricultural biotechnology.
