Ideas to review the safety rules:
1. Have students copy the rules into their lab notebook.
2. Assign each student one rule. Have them create a poster "advertising" their rule. I keep these up in the room all year.
3. Have students act out (or preferably video tape) skits with one specific safety rule broken. See if other students can identify the inappropriate action. (I include a "video portion" on my science safety test.)
(please add more) :)
