Which variable do scientists measure when they change the independent variable? (Hint: graphed on the y-axis)

• Control
• Dependent variable
• Extraneous variable
• Independent variable

What is the scientific term for the original experiment in which no experimental group is used? (Hint: what is the group called that we compare the experimental group to?)

• Dependent variable
• Experiment
• Control group
• Experimental group

Which variable does the scientist change during the experiment?

• Dependent variable
• Control
• Extraneous variable
• Independent variable

What is the part of the scientific method that includes what we found out during our experiment and if our hypothesis was correct?

• Hypothesis
• Conclusion
• Observations
• Data

Think back to our borax experiment, which of the following would not have been an independent variable?

• Borax
• Glue
• Water
• Bounciness

Thinking back to our borax experiment, which of the following did we consider our control group?

• Borax Lab Part II
• The amount of glue
• The amount of Borax
• Borax Part I

When writing an experimental procedure it is important to only change 1 variable because,

• Changing one variable will allow us determine the effect it has on our experiment
• Changing one variable keeps the experiment less confusing
• Changing one variable will keep the dependent variable from changing
• You can change more than one variable at a time to speed up the experiment
