1. Measurement – A Common Language
Lesson 3 Chapter 1
Measurement –
A Common Language

2. Standard Measurement System
Metric system
Developed in France
Based on the number ten
Using the international system of units (SI) as the standard system of measurement allows scientists to compare data and communicate with each other about their results

3. What looks easier to remember?
2.5 centimeter = 1 inch, 12 inches = 1 foot, 3 feet I yard, 1760 yards 1 mile OR
10 centimeter = 1 decimeter, 10 decimeter = 1 meter, 10 meter = 1 decameter, 10 decameter = 1 hectometer, 10 hectometer = 1 kilometer

4. Drive for 18 meters, turn left, then you will find the house 1 kilometer down on the right.
Fahre fȕr 18 meters, nach links biegen, dann wirst du denn House nach 1 kilometer am rechts finden.
Both the man and the woman are saying the same thing, although there are two very different languages, both can use and understand the same distance because of the International system of units SI system
American woman
German man

5. Prefixes Milli- 0.001 One thousandth of a unit
Centi One hundredth of a unit
Deci- 0.1 One tenth of a unit
None- 1 unit
Deka- 10 unit
Hecto- 100 unit
Kilo unit

7. Length
Distance from one point to another
SI for length is the meter

8. Mass The measure of the amount of matter in an object
SI for mass is the Kilogram
1000 milligram = 1 gram
1000 grams = 1 kilogram
Triple-
beam
balance

9. Weight Is the measure of the force of gravity acting on an object.
A scale is used to measure weight
Would a person weigh the same or different on the moon? Why??

10. Volume The amount of space an object or substance takes up.
The SI for measuring volume is cubic meter (m³), cubic centimeter (cm³), and liter (L).
Cubic meters and centimeters are used for measuring volume of a solid.
Liter is used for measuring liquids.

11. Volume continued Volume of rectangular solid = length x width x height
Volume of liquid = liquid measured in graduated cylinder
Volume of irregular solid
= liquid displaced when
solid is added to graduated
cylinder.
Measured at meniscus

13. Density How much mass is contained in a given volume
The SI for measuring density if kilograms per cubic meter (kg/m³), grams per cubic centimeter (g/cm³), or grams per milliliter (g/ml).

14. Both bars of gold will have the same density.
Density continued
All densities of pure substances are the same despite how big or small
Water density is 1 g/cm³ so items with a density less than 1 g/cm³ will float on water, items more dense than 1 g/cm³ will sink.
Both bars of gold will have the same density.

15. Temperature
Temperature is measured by scientists using both Celsius and Kelvin. Kelvin is the SI unit for temperature.
Kelvin has no negative numbers.

16. Boiling point of water
Freezing point of water
Absolute zero

17. Time The second (s) is the SI unit used to measure time.
Also uses the prefixes.
