Read each question carefully and answer to the best of your ability. Pay close attention to details about measurement and instrument precision.
When we measure things in science, it's important to use the right tools and read them carefully. Precision refers to how close repeated measurements are to each other, while accuracy refers to how close a measurement is to the true value. Understanding how precise an instrument is helps us get good data.
1. Which of the following best describes the precision of a measuring instrument?
How close a measurement is to the true value.
How consistently the instrument gives the same reading.
How easy the instrument is to use.
The size of the instrument.
2. A ruler marked in millimeters is more precise than a ruler marked in centimeters only. True or False?
True
False
3. The smallest unit an instrument can measure is called its .
4. To ensure accurate and precise measurements, you should always read the instrument at eye level to avoid error.
5. A student measures the length of a pencil three times and gets 15.2 cm, 15.3 cm, and 15.2 cm. The actual length of the pencil is 16.0 cm. Are the student's measurements precise? Are they accurate? Explain your answer.
6. Look at the image of the measuring instruments below. Which instrument would you use to measure the volume of a liquid with the most precision? Explain why.
