Positives

• This worksheet is a simple way for students to think about natural resources and how much water is wasted.
  
• Students will gain perspective regarding the myriad of ways we use water each day. 

Additional Prerequisites

• Students should be familiar with the ways people use water.
• In order to complete this worksheet independently, students will need to know how to measure volumes of liquid, add, and subtract.
  

Differentiation

• This resource would be well suited for elementary science or math classes that are working on water conservation or adding and subtraction word problems.
• This resource would be a great activity after discussing the ways people use water (bathing, drinking, cooking, flushing the toilet, agriculture, and more). 
• After completing this activity, a great extension would be for students to come up with some action items that would reduce their water consumption. 
• Have advanced students measure how much water comes out of their hose in one minute and then calculate the gallons of water used to water grass over a given surface area.
• Have students find out how many gallons of water their toilets use each time they flush and then have them calculate the water savings of low-flow toilets over a given period of time.
