In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners build small animated toys that move.

In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

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

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.
