• conclusions

• data

• hypotheses

• procedures

How many independent variables should you have in an experiment?

• two

• as many as possible

• four

• one

Which are part of the scientific method?

• Identify the Problem

• Perform an Experiment

• Form a Hypothesis

• Collect lots of money

• Communicate the Results

What is an independent variable?

• What a scientist changes in an experiment to test their hypothesis

• What scientist measure to see if it responded to a change

• What happens when you do an experiment

• What you keep the same throughout all experimental groups

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

• Hypothesis
• Research
• Observation
• Conclusion

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

• conclusion
• procedures
• materials
• responding variable

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

Will a construction paper air plane fly faster than an airplane made from notebook paper? Choose the best hypothesis.

• If I make a paper airplane from notebook paper, then it will fly faster than construction paper.
• Yes.
• No.
• I think the construction paper air plane will fly faster.
