In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.

Students build a model that demonstrates an important contributor to sea-level rise – how water volume increases when the temperature of the water increases.

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 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 will investigate the action-reaction principal (Newton's third law of motion) by creating water-propelled engines and changing different variables to see how their engines perform.

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

In this illustrated problem set, students use pi to detect frost in lunar craters, determine the density of Mars' liquid core, calculate the powered output from a dam, and find out how far a spacecraft travels as it returns data to Earth.
