0.2 The Nature of Science/The Scientific Method

What is the purpose of following the steps of the Scientific Method?

• To modify the steps depending on the experiment

• To test things in the most accurate and valid way

• To repeat steps multiple times

• To ask questions about things

What is a hypothesis?

• A well-informed guess

• A measurement of data

• A chart or graph

• A question about things

What is important when conducting an experiment to test a hypothesis?

• Changing multiple conditions at a time

• Keeping all conditions the same except for one

• Using different types of seeds in each plant

• Conducting the experiment only once

How should data be analyzed in the Scientific Method?

• By presenting it on a display board

• By writing a final report

• By collecting measurements in a chart or graph

• By repeating the experiment several times

What should be included when communicating the results of an experiment?

• The question asked and the hypothesis

• The list of materials used

• The steps of the experiment

• All of the above

What is the independent variable in an experiment?

• The thing scientists are looking to see change

• The one variable that the scientist changes

• The experiment where nothing is changed

• The things that change in an experiment

What is the dependent variable in an experiment?

• The thing scientists are looking to see change

• The one variable that the scientist changes

• The experiment where nothing is changed

• The things that change in an experiment

What is the control in an experiment?

• The thing scientists are looking to see change

• The one variable that the scientist changes

• The experiment where nothing is changed

• The things that change in an experiment

What should you only change in an experiment to ensure valid results?

• The dependent variable

• The controlled variable

• The independent variable

• The control

What should you do if your results don't prove your hypothesis?

• Conduct further experiments

• Change the dependent variable

• Change the independent variable

• Do more research and create a new hypothesis
