Metric Terms and Meanings
Systems InternationalUsed through out the world so it’s a
system used internationally
What the heck is SI?
Masswww.library.thinkquest.org
Used to demonstrate “HOW MUCH”
In the science lab we use a triple beam balance
Weight is not mass- weight is the force of gravity pushing down on you or the object
SI for Mass
kiloGram=k g
1 gram is the same as 1mL
1000g= 1 kilogram
You measure small things in grams and large things in kilograms
A mouse would be 200 grams and not 200kg or he could sit on the school!!
Mass Equilavents
1000 g = 1 kilogram kg 1000
1/1000g = 1 milligram mg .001
1/100g=1 centigram cg .01
So your one piece of hair would be .oo1g in mass
Your book bag would be 1000g=1kg
Volume of a solid
You sometimes cannot mass an object so you still have to know how much space it takes up..this is called VOLUMEHow much space a solid object takes up is easy---use the formula for areaA=length x width but it takes up air space so use V=lengthxwidthxheight
Volume of a Liquid
Liquids like water take up space so they have VOLUME so we use the common measurement for LIQUID VOLUME AS LITER with the symbol as L
You use the beaker or graduated cylinder to measure the liquid.
Metric Unit for Length
A meter is about the length of your arm from your nose to your middle finger.
A meter measure length—from one point to another
A meterstick measures meters.
Metric review for quiz
1. Mass is the amount of ______ something has.
2. Gram measures __________
3. Formula for volume of a solid is_____
4. The basic unit of volume is _______
5. The amount of space something takes up is__________
6. One meter = __________ centimeters
7. Which unit of measurement would you use to measure?
8. Length of an ant
9. Mass of a postage stamp
10. Volume of a large jug of milk
11. Mass of a truck
12. Calculate the volume of block: 4 cm L, 2 cm w, 1.3 cm High
Density
Density = Mass(g)/Volume (mL)
Density of water is 1g/ml so if something floats it has a density less than one
If something sinks, it has a density grater than one.
