Lesson Summary: In this lesson, students will engage in a hands-on investigation to explore the effects of pollution on water quality. They will start with a clean pail of water and gradually add soil, leaves, and other pollutants. Throughout the experiment, students will observe and document the changes in the water's appearance, smell, and overall quality in their journals. This activity will help students understand the impact of various pollutants on water ecosystems and the importance of maintaining clean water sources. By analyzing their observations and reflecting on the consequences of pollution, students will develop a deeper appreciation for environmental stewardship and the need for sustainable practices.
