TPACK is an interesting, and I believe accurate, way to connect important components of teaching to incorporate technology in the classroom. It both distinguishes knowledge a teacher must have into 3 distinct groups, content, pedagogy, and technology, and illustrates the relationships among them. I believe it can help teachers better understand the dynamics of their lesson plans, especially when they are learning to integrate technology in their classrooms. It is a good model teachers can reference as they seek, as the wiki TPACK website called it, "true technology integration." The ability to distinguish between each of the three groups and to use their relationships is also important for teachers so that when they develop their lesson plans, focused on certain objectives, they can clearly think about the different components they need to use and emphasize in the lesson. It is encouraging to think of teachers learning to identify all of their knowledge in the 3 different components of TPACK and to then to use their knowledge effectively as they try to integrate technology.

As for the science websites we explored, I am so excited about Google Sky! I already knew about Google Earth and have played with it many-a-time, but I had never heard of Google Sky! When I think about the educational values in using this program, my mind is flooding with exciting ideas for my students to explore space. What's absolutely marvelous to me is that the images are real, and so students can actual zoom in on Jupiter or various stars to see for themselves that they really do match up to what they've seen in storybooks. It is wonderful to give students "the big picture" of the grand scope of space as well. It will be so thrilling to develop lesson plans in which students can do things like scavenger hunts for different points in space, or report their observations of different locations or the distances between, or so many other things! I have been skeptical before about just how much the computers can provide elementary school students beyond special projects or regular word processing, but exploring these websites has opened my eyes to a world of more engaging, meaningful instruction.
