Scientific Method

What is a constant/control in an experiment?

• Things that change in an experiment.

• The variable that stays the same.

• The main factor being tested in the experiment.

• The outcome that is measured in the experiment.

What is a hypothesis?

• A testable prediction about the outcome of an experiment.

• A definitive conclusion drawn from data.

• An untestable statement about a phenomenon.

• A random guess about the results of an experiment.

What is the final step in the scientific method?

• Write a conclusion about your results.

• Formulate a hypothesis based on observations.

• Conduct experiments to test the hypothesis.

• Analyze data and draw conclusions.

What is a scientific theory?

• A hypothesis that has not been tested.

• A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.

• An educated guess about a phenomenon.

• A statement that can be proven true or false.

What is the importance of replicating experiments?

• To ensure that results are consistent and reliable.

• To make the experiments more complex and difficult.

• To reduce the time taken for research.

• To increase the number of variables in the experiment.

What role does observation play in the scientific method?

• Observation is the first step in the scientific method, leading to questions and hypotheses.

• Observation is used to confirm existing theories without generating new questions.

• Observation is the final step in the scientific method, summarizing the results.

• Observation is irrelevant to the scientific method and does not contribute to research.

What is the difference between independent and dependent variables?

• Independent variables are measured in the experiment, while dependent variables are changed by the scientist.

• Independent variables are changed by the scientist, while dependent variables are measured in the experiment.

• Independent variables are always constant, while dependent variables can vary.

• Independent variables are the same as dependent variables.

Why do scientists use the scientific method?

• To ensure their results are valid and can be replicated by other scientists.

• To make their experiments more complicated and difficult to understand.

• To avoid using any form of technology in their research.

• To guarantee that their hypotheses are always correct.

What is data analysis?

• The process of collecting data for research purposes.

• The process of interpreting and making sense of collected data.

• The process of storing data in a database.

• The process of visualizing data using charts and graphs.

What is a scientific law?

• A theory that explains why things happen in nature.

• A statement based on repeated experimental observations that describes some aspect of the world.

• An untested hypothesis that requires further investigation.

• A collection of facts that are universally accepted without question.
