Students explore the science behind an intriguing planetary feature by creating saline solutions and then observing what happens when the solutions evaporate.

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.

Students learn about cloud types to be able to predict inclement weather. They will then identify areas in the school affected by severe weather and develop a solution to ease the impacts of rain, wind, heat or sun.

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

This six-part video series walks educators and students through the ins and outs of crafting a science fair project.

Students learn about Earth processes by simulating and examining lava flows from a volcano model made of play dough.
