In this blended activity supporting science and literacy skills, students explore how energy is transformed in a roller coaster. The resource features video, interactive assessment, and an animated tutorial -- blended with informative text and vocabulary skill-building. It was developed to promote deeper understanding of energy as an agent of change that moves the car along the track. The animation and video clip will help students visualize how potential energy is transformed to kinetic energy (and the reverse) through mechanical power and the force of gravity. The literacy exercises promote the language of science and accurate concept formation.
