WHAT’S WRONG WITH THIS SCENARIO? • Rose was heating a test tube. She didn’t put on safety goggles because she was wearing glasses. She pointed the open end of the test tube away from herself but towards her lab partners on the opposite side of the lab table. • Use your lab safety contract to determine what safety rule(s) have been violated.

WHAT’S WRONG WITH THIS SCENARIO? • Barbie and Ken accidentally break a beaker full of some chemical.
