Chapter 1C- Using Mathematics for Scientific Discovery

Why do scientists use the SI?

• To maintain consistency in measurements

• To make their work harder

• Because it is the only system available

• To confuse the data

How do we collect data?

• By guessing

• Using scientific instruments

• By asking people

• Through intuition

Why do I need math to do science?

• To make calculations and analyze data

• Because it is a school requirement

• Math is not needed in science

• To write scientific papers

Aren't accuracy and precision the same thing?

• Yes, they are the same

• No, accuracy is about correctness, while precision is about consistency

• Accuracy is not important in science

• Precision only applies to mathematics

What can I tell about a scientist's instrument from his measurements?

• The color of the instrument

• The size of the instrument

• The accuracy and precision of the instrument

• The age of the instrument

How can I change units in the SI?

• By using conversion factors

• By guessing

• Units in the SI cannot be changed

• By creating new units

What happens when scientists are not accurate?

• Their results are trusted more

• They win awards

• Their results may be questioned or invalid

• They are promoted
