Ask your students to list the top 10 water uses in and around their households. From the same list, ask them to rank them in importance.

How much water do you use every day? How do you use it? The average person in a single family home uses 150 gallons each day. The average person in an apartment or condominium uses 110 gallons each day.

1. Estimate how much water your family uses:
# of family members x gallons = Estimated total water used per day, on average by family.

2. Look at the pie charts which show the percentage of water used for different activities for single family and multifamily residences. With these percentages, figure out how many gallons your family may be using (on average) for the seven uses described.

3. Once you know the number of gallons, plot and fill in the bar graph. Compare your results.
