How Much Water Do Humans Need?

Curated and Reviewed by Lesson Planet

Physical or life science learners measure the amounts of water eliminated by intestines and the urinary system, and the amounts lost via respiration and perspiration. In doing so, they discover that the body's water must be replenished regularly. Consider crafting a lab sheet or projectable instructions to prevent having to repeat the procedure several times. Another option would be to conduct this lesson as a demonstration rather than as a group activity.
