In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

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

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

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

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

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

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

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 two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

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

In this activity, learners construct paper airplanes that twist and turn.

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

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners explore clouds and how they form.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
