• 2 packets of unflavored Jell-O• 2 packets of sugar free orange Jell-O• 2 packets of sugar free cherry Jell-O• 1 cup of water• Medium-sized pot• 3 ice cube trays• Freezer• 180 cups (Labeled A or B on bottom)• Pretzels• Gummy Bears

Procedure

Before the testing:1. Make the homemade gummy bears.2. Separate the homemade gummy bears into ‘A’ cups, and

the store-bought into ‘B’ cups.While testing:3. Ask if subject has any allergies, then have them close their

eyes.4. Give each subject a pretzel, then sample A, then a pretzel,

• Some subjects may have viewed the samples before testing.

• Subjects may have received a flavor they did not prefer. (Cherry or Orange)

Conclusion

The results of the lab were inconclusive. Nearly half of the subjects preferred homemade, and nearly half preferred store-bought. In order to get more get more accurate results, there should be a greater number of test subjects.Next time, there could be a comparison of how many male and female subjects could differentiate between homemade and store-bought gummy bears.
