Presentation Transcript

  1. Spit Lab

  2. Macromolecule Carbohydrate Starch Polysaccharide Monomer Glucose Monosaccharide

  3. Indicators • Iodine tests for the presence of starch • Light brown = no starch • Dark purple or black = starch

  4. Indicators • Glucose test strips test for the presence of glucose • (Insert the specific color scale here)

  5. How to make a spit tube: Demonstration • Keep cracker in your mouth until it is runny • No chunks • Very wet with spit • You will want to swallow it, but don’t!

  6. Part 1: Test for starch

  7. Part 2: Test for sugar

  8. Part 3: Effect of temperature

  9. Medium amount of glucose High amounts of glucose Negative Small amount of glucose

  10. 100 75 50 25 0 Enzyme Activity 0 50 100 150 200 250 300 Temperature degrees Fahrenheit

  11. Glucose concentration/ Enzyme activity (Add units) 0 50 100 150 200 250 300 Temperature degrees Fahrenheit
