Units of Measurement
In this course we many times measure the materials we use. Therefore we use the metric system, the
internationally
accepted units of measurement, chiefly in our classes.
The metric system is very easy. All you have to remember is that it is based on units of ten (10), and when you use these units, they can be used to measure how much space (volume), mass and distance.
1. grams-measures mass (how closely particles are packed)
2. Iiters-volume
3. meters-distance
You will make your own meter ruler, or you can buy one. (See next sheet for details.)
To show you how good the metric system is, do the following and complete the chart:.
