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

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 use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

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 working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

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

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

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

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
