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 erosion. They engage in an inquiry using vinegar and chalk to simulate how acid rain causes chemical changes and erosion in nature. A good lesson for 3rd graders!
