Children's Water Festival
Chatham Kent
3 X’s a Day
Overview
Using a model of two washroom
sinks, students measure how much water is used by brushing their teeth with the water left running
and by brushing their teeth with the water used only sparingly. Students use a 2 minute timer to
demonstrate the proper time which should be spent brushing their teeth morning and night. They are
encouraged to ask questions and provide new insights on how we can save water in our homes while
still taking proper care of our health.
