Exploring Experimental Design in Science

What is the primary purpose of a scientific experiment?

• To entertain students

• To test a hypothesis

• To create new laws

• To observe natural phenomena

Which of the following is NOT a component of the scientific method?

• Hypotheses

• Experiments

• Peer review

• Conclusions

What is the final step in the scientific method?

• Drawing a conclusion

• Conducting an experiment

• Making an observation

• Formulating a hypothesis

What must scientists consider when designing an experiment?

• If the experiment is fun

• If the experiment is popular

• If the experiment answers the research question

• If the experiment is expensive

Why is it important for scientific experiments to be repeatable?

• To make the experiment more interesting

• To ensure the results are accurate

• To make the experiment longer

• To increase the cost of research

What is the role of peer review in scientific experiments?

• To ensure experiments are repeatable and results are reliable

• To make experiments longer

• To increase the cost of experiments

• To make experiments more fun

Which of the following is a basic rule for designing a good experiment?

• The experiment must show that a hypothesis is either supported or not supported

• The experiment must be fun

• The experiment must be expensive

• The experiment must be popular

What is required for the results of an experiment to be considered valid?

• They must be interesting

• They must be popular

• They must be expensive

• They must be measurable and objective

What is a scientific theory?

• An untested idea

• A hypothesis that has been widely tested and accepted

• A random guess

• A law that has been proven

What is the difference between a scientific theory and a law?

• A theory is a hypothesis, while a law is an observation

• A theory is untested, while a law is tested

• A theory is widely accepted, while a law is a universal fact

• A theory is a guess, while a law is a fact
