In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this physics activity, challenge learners to remove the bottom coin of a stack of nickels without knocking over the stack. Use this activity to demonstrate friction.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

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.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

Walk a toy to the edge of its doom, maybe it'll fall off the edge of a table, but it will safely stop right before falling.
