I am a special educator at Bowie High School, teaching Biology, Integrating the Sciences, and Algebra. This is my second year in NASA IDEA. My first year was awesome. This time around I find the online professional development site more exciting, more meaningful, and more powerful. And this is exactly what I need to fulfill my goal towards the end of 2012, to be a competent STEM educator in the school and county I serve.

Although a very widely explored topic and concept, the presentation gave it a different level of discussion. The information have been organized to appeal to a variety of learner. This is a very useful resource in a physical science classroom. Every physics and physical science educator must see.
