Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Rivers top the list of causes of erosion over time. Scholars experiment with wind, water, and ice reshaping sand. They connect the simulations facts about erosion and deposition to understand unique landforms such as the Grand Canyon and...

Here's a great geology lesson for 3rd graders on weathering and erosion of soil. After a class discussion on how nature can "move a mountain," learners take a look at how a modern phenoma called acid rain can also cause weathering and...

Show the class the world as they've never seen it before—from way above! Learners try to unravel the mysteries presented by rich satellite imagery, learn to interpret topographic maps, and study erosion by constructing their very...

Which materials are best for groundwater runoff, and which are best for percolation? Discuss the water table with several experiments about different types of soil, pollution, precipitation, and filtration. The experiments assign...

Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...
