Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

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

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

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

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

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

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

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

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

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

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Learners build devices from rubber bands to test for invisible air pollutants.

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