Paul conducted an experiment to determine which popcorn is the better buy between Wal-Mart and Orville Redenbacher's. He hypothesized that Wal-Mart popcorn would be the better buy. He cooked bags from each brand at the same temperature and time to control variables, then counted the pieces in each bag. His data showed the Wal-Mart bag had more pieces, so he concluded that Wal-Mart popcorn is the better buy since it costs less but contains more pieces.

- 2. State the ProblemWhich Popcorn is the better buy!
- 3. Formulate Your HypothesisI think Wal-Mart will be the better buy.
- 4. Identify and Control the VariablesWe need to cook the popcorn at the same temp and the same time.
- 5. Test Your HypothesisNow we cook it!
- 6. Collect Your DataNow we will pour out the bags and count how many pieces are in each bag.
- 7. Interpret Your Data The Wal-Mart bag had more pieces than Orville Redenbacher’s bag.
- 8. State Your ConclusionThe Wal-Mart popcorn cost less and comes with more pieces, clearly it’s the better buy.
