Science Projects for Kids: Density and Volume

A Gallon a Day

The Gallon a Day experiment can help you appreciate how much water you use every day. Perhaps you may not realize how much water you actually you use besides simply drinking it. To understand how vital water is to your daily existence, see if you can get by using only one gallon of water for one day.

What You'll Need:

  • Plastic gallon container
  • Water

Step 1: Fill a 1-gallon jug with water.

Step 2: Now try to get through a whole day using only water from this gallon.

That means you will be using water from the jug for hand washing, teeth brushing, face washing, dish rinsing, and drinking! Use the water sparingly, and see if you can make it last the whole day!

Hint: Some of the water you can recycle, some you can't. Don't drink water you've used for washing your hands (or anything else, for that matter) or brushing your teeth. But you could use water you've washed your face in to wash your hands.
