How do you think learning about the properties of matter and energy can impact your understanding of the world around you?

Multiple Choice

Why do you think it is important to study matter and energy in physical science?

• Because it helps us understand the universe and everything in it.

• Because it is only useful for scientists.

• Because it is required in school.

• Because it is unrelated to our daily lives.

The modern form of the metric system is called the

system.

Multiple Select

Which of the following are reasons why using non-standard units, like shoe lengths, can cause problems in measurement?

• Different shoes have different lengths

• It can be confusing to compare measurements

• It is difficult to convert shoe lengths to other units

• Everyone agrees on the length of a shoe

Open Ended

Why is it important for everyone to use the same system or units when measuring?

Multiple Choice

Which three countries do not primarily use the metric system?

• United States, Myanmar, Liberia

• United States, Canada, Mexico

• France, Germany, Italy

• China, India, Japan

Multiple Choice

Why was the metric system created after the French Revolution?

• To simplify land measurement and standardize units across regions

• To make currency conversion easier

• To replace the English language

• To promote local and regional practices

Multiple Select

Which of the following are advantages of the metric system?

• It helps scientists share and compare results

• All units are based on the number 10

• It uses only local units

• It is difficult to convert between units

Open Ended

Explain how the metric system helps scientists around the world share and compare their results.

The SI unit for temperature is

Multiple Choice

If a thermometer consistently gives the same incorrect temperature reading, what does this indicate about its accuracy and precision?

• High accuracy, high precision

• Low accuracy, high precision

• High accuracy, low precision

• Low accuracy, low precision

Open Ended

Explain the difference between accuracy and precision in measurements, and provide an example of each.

Multiple Choice

In the dartboard analogy, what does it mean if all darts land close together but far from the bullseye?

• High accuracy, high precision

• Low accuracy, high precision

• High accuracy, low precision

• Low accuracy, low precision

Multiple Choice

Which of the following best describes the difference between accuracy and precision as illustrated by the dartboards?

• Accuracy is how close darts are to each other, while precision is how close darts are to the bull’s-eye.

• Accuracy is how close darts are to the bull’s-eye, while precision is how close darts are to each other.

• Accuracy and precision both mean how close darts are to the bull’s-eye.

• Precision is not related to the position of the darts.

Multiple Choice

Based on the thermometer reading of 99.1°C for boiling water, and knowing the accepted value is 100.0°C, what is the experimental value and what is the accepted value in this scenario?

• Experimental value: 100.0°C, Accepted value: 99.1°C

• Experimental value: 99.1°C, Accepted value: 100.0°C

• Experimental value: 99.1°C, Accepted value: 99.1°C

• Experimental value: 100.0°C, Accepted value: 100.0°C

Fill in the Blanks

Error is calculated as the difference between the

value and the accepted value.

Open Ended

Explain in your own words why it is important to distinguish between accepted value and experimental value when determining error in scientific measurements.
