Understanding Watersheds, Land Use, and Water Pollution: A Collaborative Exploration

This lesson focuses on the importance of watersheds, land use, and the impact of water pollution. Students will graph and analyze the Earth's land distribution, learning about different types of land such as habitable, farmable, and uninhabitable areas. They will engage in hands-on laboratory activities to investigate water pollution sources affecting local watersheds, particularly assessing the chemical properties of well water samples. The goal is to foster awareness of environmental issues and encourage solutions for maintaining clean water resources.

  30. Lab Debrief • What was the source of the fish kill here in Austin? • What are some other sources of pollution in our watersheds here in Austin? • So what? Why is this important?

  31. Making Connections… How does weathering, erosion, and deposition effect the water and land in our watersheds? -Partner Read the Article -Discuss the following • What is the problem? • What is causing the problem? • How can we fix it?
