Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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

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

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

Get all wrapped up in a lesson about skin!

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
