Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

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

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

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 explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
