Planet Science has a ton of resources about teaching, learning, and using science in the classroom.

I’ve put the main link to the site on my Teacher’s Page under Science Ideas.  However, it had one interactive activity that I thought was particularly good for English Language Learners called Get Clobbered, and I put that link on my Science page.

In the game,  players have to “dress” the scientist with the appropriate safety equipment he/she needs for the experiment they’re about to conduct.  It’s an excellent opportunity for vocabulary development, and designed so it’s accessible to Early Intermediate English Language Learners.
