These two practical activities help students to understand how nutrients are washed off the land and into water systems. They also investigate the effects of nutrients in aquatic ecosystems.
By the end of these activities, students should be able to:
- explain how pollutants are dissolved and/or carried into groundwater and surface water
- discuss how polluted groundwater may lead to polluted lakes or rivers
- explain some of the possible impacts on water ecosystems of agricultural nutrient run-off and leaching.
