What catches the child’s eye
- The cup slowly filling up from single drips
- The quiet sink while hands are scrubbing
Extensions, easiest to hardest
- Catch the drip for an hour and compare with ten minutes
- Use the saved cup of water to water the class plants
- Count the seconds while brushing teeth at home with the tap off
- Look at a picture of Utah's reservoirs and talk about snow that becomes our water
