Curated and Reviewed by Lesson Planet

Which requires more water--a bath or a shower? Given some specific criteria, learners attempt to answer the question. A video shows how long it takes to fill a gallon container using a faucet and a shower head. Using that information and the cost per unit of water, scholars compare the cost of taking a shower and a bath.
