For a resource as abundant as YouTube, you might think it would be easy to find a good video on plate tectonics demonstrating plate motion using modern graphics technology. This website/flash presentation really blew me away in how simple, instructive, and moving-graphics heavy it is. There are also moving graphics and videos built right into the presentation as well that make it extra useful. While no website is complete on its own in explaining a challenging concept, this presentation does a great job of incorporating what would otherwise be complex concepts into more simple terms. The presentation is also inquiry based as well by beginning the presentation with key questions. I tend to start off my own lessons with students observing a phenomenon and then forming a question naturally. This presentation does an excellent job of creating an inquiry-rich context for learning and acquiring some rather challenging concepts.
