Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

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

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

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 how engineers have improved roofing designs and materials in order to protect the contents of buildings.
