of measuring skills in conducting an experiment.

Explanation:
The word “measurement” comes from the Greek word “metron,” which means “limited proportion.” Measurement is a
technique in which properties of an object are determined by comparing them to a standard.
Measurements require tools and provide scientists with a quantity. A quantity describes how much of something there is or
how many there are. A good example of measurement is using a ruler to find the length of an object. The object is
whatever you are measuring, the property you are trying to determine is the object’s length, and the standard you are
comparing the object’s length to is the ruler.
In general, scientists use a system of measurement still commonly referred to as the “metric system.” The metric system
was developed in France in the 1790s and was the first standardized system of measurement. Before that time, people
used a variety of measurement systems.
In 1960, the metric system was revised, simplified, and renamed the Système International d’Unites (International
System of Units) or SI system (meters, kilograms, etc.). This system is the standard form of measurement in almost
every country around the world, except for the United States, which uses the U.S. customary units system (inches,
quarts, etc.). The SI system is, however, the standard system used by scientists worldwide, including those in the
United States.
There are several properties of matter that scientists need to measure, but the most common properties are length and mass.
Length is a measure of how long an object is, and mass is a measure of how much matter is in an object. Mass and length
are classified as base units, meaning that they are independent of all other units. In the SI system, each unit of measure has
a base unit.
