Building a Scientist Les 2

A testable prediction about a scientific investigation is a(n)

• Question
• Observation
• Hypothesis
• Experiment

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

• scientific method
• recipe
• data collection
• metric system

The information you collect while doing your experiment is called

• conclusions

• data

• hypotheses

• procedures

The independent variable is the ONE thing you _____.

• change on purpose
• control or keep constant
• measure

How many independent variables should you have in an experiment?

• two

• as many as possible

• four

• one

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

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
• responding variable

This step of the scientific method is an educated guess or a prediction. 

• Hypothesis
• Research
• Observation
• Conclusion

Why do we want to test one variable at a time?

• Because it is hard to setup a data table with more
• To know what is causing the changes. This helps us understand cause and effect.
• It is what has always been done

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
