The end of our short metric history unit, this was designed as an overview to the basic themes of why we use metric (or should). A stress on science and the democratic nature of science and ten-based measurements is my cornerstone. I like the stuff about the metric calendar best.

1. Metric System Connections and Why We Use It

2. Before Metric Subjective, Variable and Confusing

4. Volume 3 teaspoons = 1 tablespoon 3 tablespoons = a jigger 2 tablespoons is 1 fluid ounce 8 fluid ounces = 1 cup 2 cups = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon 55 gallons = 1 barrel of oil 63 gallons = 1 hogshead

5. Length: Distance METER

6. Volume: How Much Something Holds LITER

7. Mass: Density/Weight Related GRAM

8. Metric Basics to Remember

9. French Republic Adopts Metric: 1791

10. French Revolution Ideals Liberty Fraternity Equality The metric system was not based on kings or trade guilds, or used archaic and seemingly random conversion numbers, but on the Earth and a ten base.

11. How They Got the Meter Distance from equator to pole. Divide by 10,000 One meter

12. How Length Becomes Volume 0.1 meter 0.1 meter 0.1 meter

13. 1 Liter 0.1 meter 0.1 meter 0.1 meter

14. How Volume Becomes Mass

15. 1 Kilogram

16. Relationship 0.1 cubic meter =1 liter 1 liter = 1 kilogram of water 1 kilogram of water = 0.1 cubic meter 0.1 cubic meter….

17. 1 g = 1 cm2 = 1ml

18. Length 10 millimeters = 1 centimeter 10 centimeters = 1 decimeter 10 decimeters = 1 meter 10 meters = 1 decameter 10 decameters = 1 heptameter 10 heptameters = 1 kilometer

19. 1 Meter 1000 millimeters 100 centimeters 10 decimeters 1 meter 0.1 decameters 0.01 heptameters 0.001 kilometer

20. Words Having Meaning (in Latin) Milli = one thousandth Centi = one-hundreth Deci = one-tenth Meter = Measure Deca = ten Hepto = one hundred Kilo = one thousand

22. Metric Nuttiness Taking a good thing too far….

23. Metric Time The day, from midnight to midnight, is divided into ten parts, each part into ten others, so on until the smallest measurable portion of duration. The hundredth part of the hour is called decimal minute; the hundredth part of the minute is called decimal second.
