This Interactive Simulation Lab consists of 5 parts. The links are included and working. The step-by-step procedures include snips and are easy to follow, especially for EL Learners. In Part I, students need to use their knowledge of physics to design a Roller Coaster that is Fun & Safe. After designing the coaster, students compute Potential & Kinetic Energy and the velocity of their coaster. In Part II, students have to choose the outcome of several Bumper Car collis
