Tools of Measurement
Accurate measurement is essential in science, whether it’s the length, mass, or volume of any object. So, scientists use specialized tools to ensure consistent results.
Let’s start with measuring length using a metric ruler. The ruler shows larger marks for centimeters and smaller marks for millimeters.
For instance, if the edge of a table aligns with the fourth larger mark on the ruler, its thickness is 4 centimeters. Since 10 millimeters make 1 centimeter, the same can be read as 40 millimeters.
Now, what about measuring mass? Mass is the amount of matter in an object and is measured using a triple beam balance by adjusting sliding weights to achieve balance.
For example, the mass of this book is obtained by adding the readings, which comes up to 350 grams.
Finally, a graduated cylinder is used to measure the volume of a liquid. For example, observe the liquid level at the bottom of the meniscus—the curved surface of the liquid, which reads 60 milliliters.
Similarly, tools like barometers measure pressure, thermometers measure temperature, and atomic clocks measure time.
