• Procedure.
– Teacher prepares Jell-O cubes the night before. (Each student
requires two cubes).
– Teacher also prepares two mixtures of pineapple juice in a
blender.
• One mixture is from fresh pineapples. Remove solids with strainer.
• The other mixture is from canned pineapples. Remove solids with
strainer.
A.) Students should put each Jell-O cube on a separate dish.
B.) Students should be given both pineapple mixtures that are
labeled in small cups. (Canned vs. Fresh)
C.) Students use eyedroppers to drip each sample on the Jell-O
until the dish is full and then use the dish juice to keep drizzling.
D.) Record observations of both Jello-O samples from the
beginning of class to the end every 5 minutes.
E.) Don’t cross contaminate the samples. Please use two eye
droppers.

• Answer:
– Gelatin comes from a protein called collagen
found in animal bones.
– Fresh pineapple juice contains an enzyme
called bromelin that breaks down protein.
– The canning process denatures the enzyme
bromelin so it cannot break down collagen.
