Question

place the red circle on the answer. which method should be used to determine the type of popcorn that produces the greatest number of popped kernels? a. research articles about different ways to heat popcorn to make it pop. b. design an experiment that tests multiple types of popcorn using repeated trials. c. heat kernels of some types on an electric stove and heat other types on a gas stove. d. construct a mathematical equation that compares size and mass of kernels from each type.

Explanation:

To determine the type of popcorn with the most popped kernels, we need a method that directly tests different popcorn types. Option A focuses on heating methods, not popcorn types. Option C introduces a confounding variable (stove type) and doesn't test all types uniformly. Option D uses math to compare size/mass, not popped kernels. Option B designs an experiment with repeated trials on multiple popcorn types, which is the scientific way to collect data on popped kernels.

Answer:

B. Design an experiment that tests multiple types of popcorn using repeated trials.
