thinkcentral.com-our textbook site is one of the best things I have found
NASA.gov-perfect for looking at the universe and posting questions to astronauts
These sites allow students to manipulate new science concepts because of the up to date technology they use to integrate new scientific discoveries into their learning. They are also useful because many state are connected to these two sites, allowing the current NEST standards to be uploaded and part of their lessons
I would like to look at the gravitational forces placed on objects on different places in space using the NASA website. Students have a difficult time remembering the difference between weight and mass and the online sources they have regarding the gravitational pull of different planets on different bodies. The website allows students to "travel" to the different planets which allows them to "see" what their weight would be on different bodies in the universe.
The biggest challenge I for see is the ability to schedule time in our computer lab. The issue is the fact that with online testing and teachers who need to be in the lab at certain times for state testing, it is very difficult for teachers to get into the lab. Without this resource and the manipulation the resource makes available, it will be difficult to have our students actually see what is happening with their weight.
