Question

• Will the expensive brand or cheap brand pop more
  kernels?

3
Hypothesis

• We think the expensive brand will pop more
  kernels.

4
Materials

• 4-5 bags of two brands of popcorn
• Microwave
• Two large mixing bowls
• Paper
• Pencils
• Calculator

5
Procdure

• We tested a bag of Shurfine and Orville
  Redenbacher popcorn to make sure it was fully
  popped.
• We popped 3 bags of Redenbacher.
• We counted popped, unpopped and added for a total
  kernel count for each bag.
• We calculated percentages and graphed them.

6
Continued Procedure

• 5. We averaged the percentages and graphed.
• 6. Repeat steps 2-5 for Shurfine popcorn.
• 7. We wrote results and conclusion.

7
Variables

• Independent variable
• Brands of popcorn.
• Controlled variables
• location, people in group, microwave, plastic
  container.
• Dependent variable
• popped corn, unpopped corn, and averages.

Results

• Our results show that all bags of
  Redenbacher and Shurfine had between 397 and 446
  kernels. The recorings are between 90 and 93 for
  Shurfine, and Redenbacher is between 93 and 96.
  Our data shows that Redenbacher popped an average
  of 95. Shurfine popped an average of 91.
  Redenbacher popped 4 more kernels than Shurfine.

11
Conclusion

• We conclude that our hypothesis was
  supported because Redenbacher popped 4 more
  kernels on average. We believe that the saying
  sometimes you pay for a brand name is true
  because with Redenbacher popcorn we popped more
  kernels, and its the more expensive brand. The
  cheaper brand, Shurfine, popped less.

12
Continued Conclusion

• We also noticed Redenbacher had bigger
  kernels and was tastier. If we could change our
  project, we would compare light butter brands.
  We would probably get the same results.
