Presentation transcript:

Bell work #1 (3 columns: 1: BW#, 2: Question, 3: Answer) DO NOT WRITE DIRECTIONS: Take a Q-tip and put it in your mouth. Be sure there is a lot of saliva on it. Open the mini-agar plate that has starch in it and GENTLY draw a design. Put the lid back on. After 5 minutes, add 2-3 drops of iodine and swirl around to cover surface. QUESTIONS (Write these.): What enzyme is in your saliva? What substrate does this enzyme break down? Describe what your mini experiment showed you.

The “squiggles” are where the saliva was placed by the Q-tip.
