Big Idea # 2Big Idea # 2
• The metric system of measurement is used by scientists and is based on units of ten.
![Page 9: Measuring With Metrics. Big Idea #1 There are two types of observations: 1. Qualitative 2. Quantitative](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d815503460f94a6554f/html5/thumbnails/9.jpg)

Do we always measure with a meter stick? That seems kind of hard when we are measuring small things.
----------------------------------------------------
No ….don’t be silly… The meter can be divided into smaller sections of equal length.
![Page 11: Measuring With Metrics. Big Idea #1 There are two types of observations: 1. Qualitative 2. Quantitative](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d815503460f94a6554f/html5/thumbnails/11.jpg)

10 meters = Decameter
100 meters = Hectometer
1000 meters = Kilometer

2. displacement

To remember the formula…..picture a heart cut in half across its horizontal access. -- top half of the heart forms
the letter M; bottom half forms the letter V.

Hot and ColdHot and Cold
Hot and Cold are relative measurements
For Example:
A piece of red hot metal might be hot when compared to a cube of ice; but the same metal is significantly cooler than the surface of the sun.

Metric TemperatureMetric Temperature
• In the metric system, the difference between freezing and boiling is divided into 100 equal intervals; each called a degree Celsius.

Freezing and BoilingFreezing and Boiling
Celsius (degrees)
Boiling Point = 100
Freezing Point = 0
Fahrenheit (degrees)
Boiling Point = 212
Freezing Point = 32

Temperature ConversionTemperature Conversion
• To convert Celsius to Fahrenheit:
Multiply the temperature by 1.8, then add 32.
---------- Fahrenheit = (1.8 x Celsius) + 32

• To convert Fahrenheit to Celsius:
Subtract 32 from the temperature and
multiply the difference by .55
---------- Celsius = (Fahrenheit – 32) x .55
