Experimental Design - Cornell Doodle Notes Quiz

The components of a fair, controlled experiment are:

• a control group, independent variable, dependent variable, and constants

• a hypothesis, a conclusion, and a guess

• random guesses, uncontrolled variables, and opinions

• only one variable and no control group

A testable question is:

• A question that can be answered through an experiment or observation.

• A question that cannot be answered.

• A question with no possible evidence.

• A question that is based on opinions only.

Looking at the question: "How do the number of thorns affect how many animals eat from a blackberry bush?"

What is a possible conclusion from this testable question experiment?
