One rule: must follow the Scientific Method

The Scientific Method

Ask a Question

What temperature is best for popping popcorn?

Research

Hypothesis

My hypothesis is that cooking popcorn over high heat will produce best popcorn.

Conduct Experiment

Group 1: Low heatGroup 2: Medium heatGroup 3: High heat

Only the heat setting will change (independent variable.)

All other aspects we will try to keep the same, including time cooking (1 minute).

Conclusion: My hypothesis was wrong. High heat did not produce best popcorn; it produced burnt popcorn.

Medium heat produced best popcorn of the three heat levels tested.
