In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

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 discover if carbon dioxide has an effect on temperature.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this lesson, learners will practice graphing and statistically analyzing data.
