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 small animated toys that move.

In this project, students explore how levers work, by making a puppet with moving limbs.

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 activity, learners build their own sound machines and explore the interplay of motion and sound.

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

In this activity, learners build a seesaw powered by magnets.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners discover that some things only stand up while they are spinning.

Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

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