4.  Throw out the paper towel you used for the lipid test.  Throw out all used pipets.  Throw corn in the trash and wash the mortar and pestle  Return chemicals to the metal tray.  Wash all beakers and test tubes with soap and water. Hang to dry on rack.  Return test tube racks to the counter.  Return goggles to the cabinet.  Clean lab tables and sink.  Work on the analysis questions. CLEAN-UP
