This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity, learners use simple items to construct a device for indicating air pressure changes.
