Amylase and Starch Lab – Task Card 1. Fill the 250-mL beaker about 3 / 4 full of water and place on the hot plate for a boiling water bath. Keep the water JUST AT BOILING. 2. Mark 3 test tubes A, B and C. "Spit" between 1 and 2 mL of saliva into each test tube. 3. Into tube A, add 2 mL of vinegar. Into tubes B and C, add 2 mL of distilled water. Thump the tubes to mix. 4. Place tube B into the boiling water bath for 5 minutes. After the five minutes, remove from the bath, and place back into the test tube rack. 5. Add 5 mL of the starch solution to each tube and thump to mix. Allow the tubes to sit for 5 - 10 minutes, occasionally thumping the tubes to mix. 6. Add 5 mL of Benedict's solution to each tube and thump to mix. Place the tubes in the hot water bath. The reaction takes several minutes to begin.
