Science Content:
Describe Earth's resources including rocks, soil, water, air, animals and plants and the ways in which they can be conserved.
Investigate positive and negative impacts of human activity and technology on the environment.
Explain how the solution to one problem may create other problems.
Estimated Time: Part 1- 1 hour Part 2- 30 minutes
During this lesson students will use a model of a water supply and city to simulate the effects of water pollution and explain how it impacts the each body of water as well as brainstorm a solution. Then the polluted water will be used to develop a plan to clean the water.
Part 1: Students will sit around a large model of a city and read situation cards in small groups and carry out the procedures to pollute the water sources. Throughout this simulation, students will use a journal to record cause and effect of the pollution scenarios and a possible solution. Once all scenarios are read the class will discuss cumulative problems and how this impacts the city.
Part 2: Using the polluted water, students will work in a small group with a set of materials to plan and create a method to clean the water. They will share and discuss the results of their investigation as a class.
