This document outlines a 6-8 week project-based learning activity for an 8th grade class involving designing, building, and launching a water rocket. Students will research rocket design using the internet, decide on materials, and make diagrams. They will learn about force, friction, aerodynamics in physics; fuel chemistry; internet technology; and engineering design through the process of constructing a water rocket model, filling it with water, attaching an air pump for launch, and assessing flight performance.
