  15. Test Tube Holds liquids for observation or testing

  16. State Test Question When heating a test tube, it is important to--- a. move it slightly so that the contents are heated evenly. b. tilt it slightly toward you so that you know when the contents are boiling. c. stopper the tube so the contents will not spill. d. tilt the tube away from you in case the contents splatter.

  17. Safety Goggles Protects Eyes

  18. State Test Question Eye protection should be used in the laboratory when--- A. reviewing the contents of the scientific supply area. B. operating a compound microscope. C. testing any hypothesis. D. chemical fumes might be present.
