Want a fun way to address Lab Safety. Have kids color the naughty things that the lab rats are doing. They will be shocked at how many spoken and unspoken rules the rats got caught breaking.
This can be easily modified and used in a variety of ways. Students could make lists as they are coloring their picture if you want to spend more time or just circle the naughty things if you are wanting to spend less time.
This is set for 8.5 x 11 size but works well to blow up to 11x17 for bigger pages to use with groups.
