Here's what you'll need:
- A bucket
- A measuring cup
- A stopwatch
- A calculator
Here's what you do:
2. Let the water run for 15 seconds.
3. Measure the amount of water in the bucket using the measuring cup.
4. Multiply this number by 4 for the amount of cups per minute.
5. Divide this number by 16 (there are 16 cups in a gallon) to get the number of gallons per minute.
6. Be sure to use the water from your investigation to water house plants or refill a pet's water dish.
For example: Frannie's bucket had 10 cups of water in it after 15 seconds.
10 cups x 4 = 40 cups/minute
40 cups/minute ÷ 16 cups/gallon = 2.5 gallons per minute.
So if Frannie took a 10 minute shower, she would have used 25 gallons of water. That's a lot of water! Some older showerheads use more water than this, if you find that your showerhead uses significantly more water, talk to your parent/guardian about switching it out for a water-efficient showerhead!
