(lesson on Monday, Sept 14, 2009)

This class' lesson was the introduction of the International System of Units aka SI. We learned that it consists of 7 metric units. These include metres for length, kilograms for mass and weight, and metres cubed for volumn. We also learned the metric prefixes, which is a syllable attached to the beginning of a metric unit to make it larger or smaller. Examples would be:

- kilo- (k) which means 1000 and is 10 to the power of positive 3. (to make a unit larger)

and..

- milli- (m) which means 0.001 and is 10 to the power of negative 3. (to make a unit smaller)



That is all. Mr. Doktor is the best.
