input: [Description] Water Tower Challenge Lesson focuses on water storage and how engineering helps communities preserve and supply water to populations. Students work in teams to design and build a water tower out of everyday materials that can "supply" and "shut off" water as needed. The system will need to deliver water in a controlled manner to a paper cup that is about 36 inches or 90 centimeters away in a controlled manner. They design their tower, build and test their system, evaluate their results, and share observations with their class. [Ages] 8 - 18 [Category]
