How much pee is in this pool? (Archived)
After chlorination, it has been hard to measure the quantity of pollutants in pool water. A Canadian chemist, Xing-Fang Li, has found a marker for urine that chlorine doesn't disguise. In this activity, students calculate volume of several pools, change that cubic foot volume to gallons of pool water, and try to approximate how much urine is in each pool. You might kick this activity off with this silly clip from the 2010 movie Grown Ups, where Kevin James is caught peeing in the pool.
