You might want to ask the students to try to determine alternative ways to measure how much water they use. Students graph data and calculations. Discuss adaptations plants and animals make in their use of water. Students keep track of their entire households use of water. Students start a school water conservation program.
Students assess how environmentally aware their family is by a point system.
Goal is to heighten awareness of environmental impact. Students collect data on a point system. If you recycle newspaper, used computer paper, and some junk mail, add 10 pts. If you picked up litter in the past week, add 5 pts. If you littered in any way.
