Objective:
This activity is a wrap up of the previous activities and a review of the importance of water on our planet.
Materials:
- A copy of Earth Aid video.
Earth Aid Video
This video focuses on how to help improve water quality. It features Ed Begley, Jr. demonstrating a wealth of innovating tips on water conservation that cost us nothing but can save up to 50% of the water used by each of us. Some of the simple ways to conserve our water use, and pollute less are:
- not leaving the faucet running.
- putting displacement devices in toilets.
- watering lawns less frequently and more efficiently.
- installing low-flow faucet aerators.
- installing low-flow shower heads.
The video reviews concepts from earlier units, such as: even though the world is mostly covered with water, very little of it is drinking water. To limit polluting that drinking water, the video suggests not pouring pollutants such as oil or paint in places where it can reach the ground water, and using soaps that do not contain phosphates.
Discussion:
- Students should review earlier lessons.
- Students should discuss how to conserve water more carefully.
- How can they conserve water at home? At school?
