3. Conserve Water
Many suggestions for conserving water, like running your dishwasher only when it's full, are geared toward adults. But there is an easy way to teach kids that every drop counts.
Take drinking glasses, for example. While I'm thankful my kids like to drink water, I can't stand the dozens of half-full glasses that end up inside the sink because everyone forgot whose was whose. With the average faucet flowing at about 3 to 5 gallons per minute, we were wasting 10 to 12 gallons of water a day with all this unnecessary washing.
To put an end to the pileup in the sink and better keep track of everyone's glass, we decorated plain wooden clothespins with each child's name and attach it to the rim of the glass they receive in the morning. At the end of the day, the kids turn in their glasses and clothespins so they can pin a fresh cup in the morning. Now we wash less and the kids play a part in saving water every day.
