Definitions

  • Hypothesis- An educated guess to a scientific problem.

  • I.V.- The variable that changes in an experiment.

  • D.V.- The variable that is being tested or measured in an experiment.


Definitions1

Definitions

  • Control Group- The group in an experiment that is treated normally. EX: Giving a plant water versus giving a plant Dr. Pepper.

  • Experimental group- The group in an experiment that is being experimented on.

    Ex: Giving a plant Dr. Pepper versus giving it water.

Definitions

  • Constant- Things in an experiment that remains the same between the control group and experimental group.

  • Control- Factors in an experiment that the Independent Variable compares to.


Scenario 1

Scenario 1

  • Title: Answers can vary; The effects of Starbucks Coffee on Cancer Tumors.

  • Hypothesis: Starbucks Coffee does or does not reduce the size of cancer tumors.

  • I.V.- Starbucks Coffee

  • D.V.- Size of the Tumor

  • Constants: Amount of days(6 Months) , X-ray


Scenario 2

Scenario 2

  • Title: The effects of Breakfast on Thinking Ability

  • Hypothesis: Breakfast does and does not play an important role in one’s ability to think.
