This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat being trapped on our warming world.

Students use global temperature data to create models and compare short-term trends to long-term trends.

Students use a spreadsheet model to understand droughts and the movement of water in the water cycle.

Students observe the process and results of transpiration from a plant in their schoolyard.

Using real data from NASA’s GRACE satellites, students will track water mass changes in the U.S.

Students use satellite data to help determine the greatest renewable energy potentials in any given region and develop graphing skills.

Students work in teams employing an iterative design process to design and build a water filtration device using commonly available materials.

Students make predictions and observations about how ice will melt in different conditions then compare their predictions to results as they make connections to melting glaciers.

Students explore the science behind an intriguing planetary feature by creating saline solutions and then observing what happens when the solutions evaporate. Now updated with findings from Mars!
