Independent vs Dependent Variables

Using the "cheat" DRY MIX

• DRY is for the dependent variable.

• D = dependent

• R = responds to the experiment

• Y = on the y-axis

Using the "cheat" DRY MIX

• MIX is for the independent variable.

• M = manipulated the experimentor

• I = independent 

• X = on the x-axis

Multiple Choice

A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at 2 years. What is the INDEPENDENT variable?

• amount of time

• weight

• growth hormone

• type of cow

Multiple Choice

A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at 2 years. What is the DEPENDENT variable?

• amount of time

• weight

• growth hormone

• type of cow

Control Variables

Some variables in this experiment are kept the same:
- Time (2 years)

- Type of cow
- Environment
It is important to keep all variables except the independent variable the same to get accurate results.

Multiple Choice

The independent variable is the ONE thing you _____.

• change on purpose
• control or keep constant
• measure

Multiple Choice

The variable that is being measured or observed is called the _______________. Hint: this is the variable that is the result or effect

• independent variable

• dependent variable

• control variable

Multiple Choice

What is a constant/control in an experiment?

• Things that do not change in a experiment. It's the variable that stays the same. You can have many variables stay the same.

• It's the variables that the scientist changes in the experiment

• It's the variables that are being measured in an experiment

Multiple Choice

How many independent variables should you have in an experiment?

• two

• as many as possible

• four

• one

Multiple Choice

Which of the following shows the correct sequence for the scientific method inquiry?

• Conclusion, Experimentation, Hypothesis, Observation

• Observation, Experimentation, Hypothesis, Conclusion

• Observation, Hypothesis, Experimentation, Conclusion

• Experimentation, Conclusion, Observation, Hypothesis
