  1. JELL-NOOOOOOO! Laboratory Investigation

  2. 1. Title of experiment: • “The Affects of Pineapple Juice on Jell-O”

  3. 2. Purpose of the experiment: • The purpose of the lab is to understand why the Jell-O did not set.

  4. 3. Hypothesis (Write as an “If-then” statement): • If the enzyme bromelainis added to Jell-O, then the Jell-O won’t set.

  5. 4. Prediction: • Because fresh pineapple has the enzyme bromelain, it will cause the Jell-O to not set.

  6. 5. Materials List: • Jell-O • Fresh pineapple • Canned pineapple • Etc.

  7. 6. Data Table:

  8. 7. Control group: • The control group is the Jell-O with nothing added to it.

  9. 8. Independent variable: • The independent variable is the type of pineapple used (fresh vs. canned).

  10. 9. Dependent variable: • The dependent variable is whether or not the Jell-O sets.

  11. 10. Procedure: • Make Jell-O according to package instructions. • Add fresh pineapple to one sample. • Add canned pineapple to the other sample. • Refrigerate.

  12. 11. Conclusion: • Because the fresh pineapple has the enzyme bromelain, it does not allow the Jell-O to set. Because the canned pineapple does NOT contain the enzyme (due to it being destroyed by the heat of the canning process), the Jell-O will set.
