Arizona Water Consumption

Time: 30-40 minute lesson for grades 4-8

Lesson description: This activity has students discover how their personal water consumption for a specific set of activities compares to yearly rainfall averages in Phoenix. The activities addressed go beyond the often mentioned indoor water-use activities (flushing the toilet, brushing teeth, washing dishes) and reveal how activities less intuitively associated with water use a considerable amount of water. Completion of the activity leads students to discover that their activities consume a significant amount of water especially when compared to the amount of rain that falls where they live. The discovery is designed to challenge students to think about ways to conserve.

Suggested subject areas: Science and/or social studies
