Math Skill: Addition &  Number comparison (1-digit numbers)

Science Skill: Earth Water

Grade level: 1st grade

Environmental Area: Water

Purpose: Understand how much water is consumed for daily activities and develop awareness of water conservation

BACKGROUND FOR THE TEACHER

The average person uses 100 gallons of water every day.  Washing hands requires about 2 gallons of water and taking a shower for ten minutes requires 38 gallons of water. Most of the water we use every day comes from the Ohio River. River water is precious because it accounts for only 0.00015% of the total water on Earth. To raise awareness of water conservation, it is important for your students to realize how much water they consume every day.
