PUMPS

OBJECTIVES: Students will learn the basic types of pumps and how they work in terms of pressure, velocity, and elevation differences. They will build a gravity-driven water pump to perform a simple action. Using an interactive activity students will "solve a mystery" using their knowledge of pressures and pumps. NATIONAL SCIENCE STANDARDS: Forces and Motion, Energy, Measurements (Unifying Principles) MATH STANDARDS: Problem Solving, Algebra ENGINEERING SKILLS: Application of Science Principles to Engineering, Construction, Basic Thermodynamics
