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!

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

In this illustrated math problem, students use the mathematical constant pi to determine the water output of a dam to assess its potential environmental impact.

Students learn to describe meteorites and rocks using candy bars as familiar models.

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic.

Students learn the difference between land ice and sea ice and make a model to see how the melting of each impacts global sea level.

Whip up a moon-like crater with baking ingredients as a demonstration for students.
