Math Skill: Creating and interpreting double bar graphs (2-digit numbers)
Science Skill: Earth Water
Environmental Area: Water
Purpose: Learn how much water you can save by changing the way you do some daily activities and learn how small changes make a big difference
BACKGROUND FOR THE TEACHER
Replacing older showerheads, toilets, and faucets with low-flow ones is considered one of the most effective ways to reduce water use. However, there are many other opportunities for saving water even for elementary school children. For example, stopping flushing trash saves 6 gallons of water and turning off the water when putting shampoo and body soap saves as much as 38 gallons of water.

The table shows how much water you can save by changing the way you do some daily activities. Activities include turning off the water while brushing teeth, drinking juice from a reusable mug, throwing trash away in a trash bin instead of the toilet, limiting the use of running water while washing dishes, and turning off water when putting shampoo and body soap when you take a shower.

Math Skill: Creating and interpreting double bar graphs (2-digit numbers)
Using the table, students are asked to create a double bar graph to show how much water they can save if they change the way of doing some daily activities. Based on the bar graph created, they complete some questions.
