This site is absolutely perfect if you are looking for laboratory simulations. This is great if you want to do certain labs but don’t have the necessary materials to complete it. This can be used in all areas of the discipline. In particular I was thinking about electromagnetism labs that involve complicated circuits. The physics behind the circuits is in the curriculum but not building circuits yourself.
Compadre allows teachers to connect to one another. This way it would be convenient for a new teacher like me to see how certain teachers develop their curriculum so that I could use it as a model. I definitely expect to use this next year.
More than anything else, this site is a compilations of cool new things in science and technology. This could be used as motivation when introducing a new unit. It should be really easy to tie it in to the curriculum., specifically the part on nuclear physics and energy.
When studying gravity, it is very difficult to separate air resistance and relative motion. Even though gravity affects all things equally, a feather falls slower than a weight. This site would help get rid of some of that confusion as it is incredibly to the point.
