Experimental Design

What is a factor that is measured for change in an experiment?

• control
• constant
• independent variable
• dependent variable

What part of an experiment contains the data tables and graphs?

• Analysis

• Conclusion

• Hypothesis

• Materials

A summary of the experiment that includes whether hypothesis was supported or not.

• Hypothesis

• Results

• Conclusion

• Independent Variable

What is the factor that a variable changes on purpose?

• Dependent Variable

• Independent Variable

• Constant

• Control

The part of the experiment that does not contain the independent variable. Used for comparison.

• Control Group
• Experimental Group
• Results
• Data

What is an if....then statement that predicts the outcome of an experiment or how the Independent variable effects the dependent variable?

• Conclusion
• Materials
• Hypothesis
• Problem

What are the number of times each level of the independent variable is tested?

• constants

• control

• trials

• dependent variable

Students used various temperatures of water to see which one dissolved candy faster. 
What was the Independent Variable?

• Amount of Candy
• Amount of Water
• Temperature of Water
• Time for Candy to Dissolve

Students wanted to see if the type of material affected the temperature after being placed under a heat lamp for 10 minutes.

What is the dependent variable for this investigation?

• Type of material (rocks, sand etc)

• Temperature after 10 minutes

• Time under the lamp

• Heat lamp, amount of material

If plants receive more water, the number of leaves will increase. 
This is an example of 

• Testable Question
• Hypothesis
• Variables
• None of the above
