This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

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 bird that flies in place with help from a motor, wire, and some straws.

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

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.
