Mack's Measurement Thoughts

We learned about the metric system. During this chapter we learned how to measure certain things by the volume, density, temperature, distance, mass, and time. We did a couple of labs to help demonstrate measurements using scales, and measuring density, and mass.

*Only three countries have not converted to the metric system, one of those being the U.S.

(U.S., Liberia, Burma are the three countries that have not converted over)

*The metric system was developed based on decimals.

(Moving the decimal point certain places over)

*In ancient times, the foot was 11 1/42 inches. Today it is 12 inches, the length of the average man’s foot. (We use a ruler, back in the old days they used a human foot, they did not have nothing else to use.)

How is the metric system better than the non-metric system?

How are we supposed to measure something without it? We would not know the length of anything we would have to just guess. If we had to measure something and measurement did not exist we would use objects. For example, an arm, you can measure with an arm but not everyone’s arm is the same length. Without measurement how would you know what ingredients to add to certain foods or objects to make them? Life would be difficult without it.
