The Scientific Method: Pre-Test

How familiar are you with the topic of The Scientific Method.

• I know a lot about it

• I know a little bit about it

• I am not familiar with this topic

Which of the following is a possible hypothesis about amount of water and plant growth?

• All plants grow

• Plants that get more water will grow taller

• Does water help plants grow?

• If you give plants more light, then they will grow more

All of the following are important parts of a controlled experiment except

• large sample size

• having one experimental group

• having 2 independent variables

• repeating experiment

In an experiment, what is causing the changes that you observe?

• the independent variable

• your senses

• data collection

• the control group

The results of the experiment are called

• answers

• conclusions

• inferences

• theories

Which variable do you measure?

• Independent
• Dependent

The steps of the scientific method, in order are:

• Observation, Research, Hypothesis, Experiment, Collect Data, Conclusion

• Experiment, Hypothesis, Collect Data, Conclusion, Observation, Research

• Research, Hypothesis, Observation, Collect Data, Experiment, Conclusion

• Conclusion, Observation, Research, Collect Data, Experiment, Hypothesis

Which of the following is NOT part of a conclusion

• A description of the results and numerical data

• A list of errors and how they could effect the experiment

• An educated guess about the outcome of the experiment

• Suggestions to improve the experiment when it is repeated

To make sure your experimental results are reliable, you should:

• Write more than one hypothesis
• Use more than one variable
• Only do the experiment one time
• Repeat the experiment many times

The experimental group in an experiment should have

• Many different variables

• The variable that is being changed and tested

• All of the normal conditions

• Different materials than the control group
