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.
The table shows how much water on average is required to conduct daily activities, including brushing teeth, flushing toilets, and taking a shower. Students complete questions using the numbers in the table.
WORKSHEETS & ANSWER KEYS
Using the table, students are asked to compare two numbers to figure out which activity requires more/less water to do. Students are also asked to add two 1-digit numbers to find out how much water is consumed to do those activities.
