11. Heat! • Turn off hot plates and burners when not in use. • Turn off microscopes when not in use.

12. Heating Substances • When heating a substance, always point the test tube away from you and other people. • When heating over a burner (flame), gently move the test tube over the hottest part of the flame. • Use tongs or hot pads when handling hot equipment. Use a test tube holder when heating substances in a test tube.
