Science, a way of thinking YBTC 2024/#2

Why is it important to have controlled variables in an experiment?

• To ensure the experiment is more complex

• To make the experiment easier to conduct

• To make sure comparisons are meaningful

• To increase the number of variables

How can scientists ensure their results are trustworthy?

• By collecting data randomly

• By repeating the experiment multiple times

• By changing variables frequently

• By using different methods each time

What is plotted on the y-axis in a graph of experimental data?

• Independent variable

• Dependent variable

• Controlled variable

• Random variable

What should you do after conducting an experiment to ensure others can trust your data?

• Keep the data private

• Repeat the experiment

• Change the data slightly

• Use different methods each time

What is the relationship between temperature and volume of a gas at constant pressure?

• As temperature increases, volume decreases.

• As temperature increases, volume remains constant.

• As temperature increases, volume increases.

• As temperature decreases, volume increases.

What can scientists learn from invalid hypotheses?

• Nothing, they are useless.

• They can adjust or create new hypotheses.

• They should stop the experiment.

• They should ignore the data.

What is the purpose of communicating results and conclusions to the public?

• To keep the information secret.

• To allow others to learn and improve their experiments.

• To confuse other scientists.

• To sell the information.

What is the significance of using data in scientific experiments?

• Data is used to make random guesses.

• Data helps verify or refute hypotheses.

• Data is not important.

• Data is only for decoration.

What is the importance of diagrams in scientific communication?

• They are not important.

• They help visualize results.

• They are only for decoration.

• They confuse the audience.

A scientific question must be answerable through:

• direct observation

• experimentation

• hypothesizing

• using the senses, like taste
