Physics Games.net, as the name implies, is a website of games based on simple physics concepts. Physic Games offers dozens of games based on a physics concept or two. Each game can be played directly on the Physics Games website or embedded into your blog or website. The one downfall of the site is that before each game starts there is a short commercial. I checked out a few different games, and I did not see any advertising that would be unacceptable in a public school classroom.
I love Scienterrific Games. At this site, you'll find a variety of games (board games, card games, etc) to use as review with your students. They are geared more toward high school, but all the typical high school sciences are represented. The owner is a former colleague who is a total inspiration to me. The games are not free, but are VERY reasonably priced. I have used several, and my students LOVE them.
