Scientific Method

Which best describes the purpose of a control sample?

• to compare its results to those of a well-known scientist

• to have more qualitative data to analyze at the end of the experiment

• to compare its results to those with the experimental sample

This variable in an experiment is the one being changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

When we test our hypothesis, there are two types of variables. What are they?

• Independent and controlled variable

• dependent and controlled variable

• independent and dependent variable

• none of the above

This is the group that we will compare our experimental group to. This group stays "normal."

• Control Group
• Experimental Group
•  Normal Group
• Weird Group

In a controlled experiment, how many variables can be worked with at a time? 

• one
• none
• two or more
• how ever many makes sense.

At what temperature did bread mold the slowest?

• 20

• 40

• 60

• 80

What step does every scientific experiment begin with?

• hypothesis

• question/problem

• background research

• conclusion

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• data collection
• metric system

What does the picture represent?

• Hypothesis
• Conclusion
• Question/Purpose
• Experiment

If I study for my scientific method test, then I will have a better test score. What is the dependent variable?

• Scientific Method
