Discover how we impact the quality of our water.
- Students will explore types of pollution and human impacts to water
- Modules include in-depth background reading, quizzes, and ideas for lesson extensions that align with NGSS
In the "Earth and Human Activity: Water Quality" kit, students collect water samples from a local environment and test a suite of environmental parameters, including: pH, nitrates, phosphates, oil, and lead. Students are guided through the scientific method and design their own controlled experiments to investigate the effects of nutrient loading on an aquatic system. A teacher demonstration on particle settling time introduces a discussion about particulates in the environment and in drinking water.
