I'll start by sharing three different packets of games for the classroom.
- The Einstein Game (2MB; PDF) by Leon Spreyer was picked up at an NSTA conference in 1996. I have to say that it was my favourite game I ever played with students. It is a trivia game---one where any and every kid can show that they are an "Einstein" with something. It's a great time filler when you are left with an unexpected gap in a class period (e.g. snow day schedule) or just after a test when everyone needs a bit of fun.
- Games in the Middle School Classroom (35MB; PDF) is a packet of options by Kathie Owens, Sylvia Murray, and Richard Sanders. This is also from the 1996 NSTA conference. This handout has about 15 different games (some of them science specific) that you can use as learning tools for students. I didn't use all of them, but I remember having kids play some of these. We did have some rousing review sessions of "football."
- I also have an author-less collection of Games for the Classroom (16MB; PDF). Wish I could tell you more about where these came from. Some of the fonts suggest that they're contemporary with the other mid-90's stuff...but I just don't know.
