What is the final step in the scientific method?

• Write a conclusion about your results

• Record and analyze the data

• Form a hypothesis

• Research your topic

Which of the following best describes the difference between a hypothesis and a prediction?

• A hypothesis is created before experimenting and a prediction is created after the experiment.

• A prediction is created before experimenting and a hypothesis is created after the experiment.

• A prediction is a specific statement regarding how the hypothesis will play out in your experiment.

• A hypothesis is a specific statement regarding how the prediction will play out in your experiment.

What is a control group?

• A group during an experiment that does not receive the experimental treatment

• A group during an experiment that does receive the experimental treatment

• A group in which the hypothesis does not apply

• All of the things in an experiment that are kept the same.

To accurately test a hypothesis, one must be careful to eliminate all variables except for the one in which you are studying. What is the name for all of the parts of the experiment that are kept the same between the control group and the experimental group?

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...
