Question

lab station #5 measuring length in metric system

1. if you were to measure the diameter of a quarter, you would measure in: mm, cm, m or km
2. if you were to measure the diameter of a petri dish you measure in: mm, cm, m or km
3. if you were to measure the length of a pencil, you would measure in: mm, cm, m or km
4. if you were to measure the length of a table in class, you would measure in: mm, cm, m or km
5. if you were to measure the height of a classmate, you would measure in: mm, cm, m or km
6. if you were to measure the distance between school and your house, you would measure in: mm, cm, m or km

Explanation:

Step1: Consider size of quarter

A quarter is small, so mm is appropriate.

Step2: Consider size of petri - dish

A petri - dish is larger than a quarter but not very large, so cm is appropriate.

Step3: Consider size of pencil

A pencil is not too long, cm is a good unit.

Step4: Consider size of table

A table is larger than a pencil, m is appropriate.

Step5: Consider height of classmate

A person's height is usually measured in m or cm, and cm is more common for a more precise measurement, so cm is appropriate.

Step6: Consider distance between school and house

The distance between school and house is long, km is appropriate.

Answer:

1. mm
2. cm
3. cm
4. m
5. cm
6. km
