Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

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

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

In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

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

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

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

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

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
