This lesson is a excellent way to teach several physics concepts to students. The lesson brings an exciting real-life example (roller costers) to engage the students in learning the phyics behind the fun. There is an excellent use of technology in the lesson with both iPads and Podcasting being tools used to help student learning. These tools really make this lesson accessible to students of all levels and help stimulate all learning types that may be engaged. Some scaffolding may need to be done in order to ensure students get the most out of the technoloy. This lesson does a great job creating meaning for the students and allows them to interact with peers in problem-solving.
