Does it save more hot water to take a shower or a bath?
- A bathtub with a shower
- Bath crayons or masking tape
- Ask one of your family members to mark the water level each time they take a bath for three days in a row and leave the water in the tub when they are done.
- Measure the amount of water used by marking the water level on the side of the tub with a crayon or piece of tape. If you use tape, write the word bath on it each time.
- For the next three days, have the same family members take a shower instead of a bath. Ask them to plug the drain so the water fills up.
- Measure the amount of water used by marking the water level with a different color of crayon or piece of tape. If you use tape, write the word shower on it each time.
