Basics of an Experiment

What is a Hypothesis?

• An assumption

• An educated guess

• An idea

• A hippopotamus

What is the first step in the scientific method?

• Make observations

• Design and conduct an experiment

• Formulate a hypothesis

• Accept or reject hypothesis

Which best describes a Natural Experiment?

• Compare a control group with an experimental group

• An experiment that takes place in a real world setting.

• Make a prediction, gather data, uncontrolled variables

What is a Independent Variable?

• Observed variable that's effected by something else

• Variable that you changed.

• Something that is kept the same.

What is the second step of the Scientific Method?

• Make observations

• Design and conduct experiment

• Evaluate the results

• Formulate a hypothesis

Which best describes a Controlled Experiment?

• Make a prediction, gather data, uncontrolled variables

• Compare a control group and an experimental group

• Experiment that takes place in a real world setting

Which best describes a Dependent Variable?

• Variables that are kept constant or unchanging

• The variable you change.

• The variable you observe, it's effected by another variable

What is the third step in the Scientific Method?

• Design and conduct an experiment

• Evaluate the results of the experiment

• Accept or reject the hypothesis

• If needed, make and test a new hypothesis

Which best describes a Field Experiment?

• Make a prediction, gather data, variables are uncontrolled

• An experiment that takes place in a real world setting

• Compare an experimental group with a control group

Which of these best describes a Constant/Controlled Variable?

• The variable that you change, it effects the other variable

• The variable that is unchanged

• The variable that is observed, it's effected by the other variable.
