Measuring Notes

Matter:

Anything that occupies space and has mass.

Volume:

The amount of space something occupies.

Regular Shaped Objects: L x W x H = _____cm^3

Irregular Shaped Objects: Use a graduated cylinder to measure displaced water. 1 mL of water equals 1 cm^3. The object pushes the water out of its original place. The amount of displaced water equals the volume of the object.

Liter (L), milliliter (mL)

Meniscus- The water clings to the sides of the graduated cylinder. This creates 2 possible spots to measure. We measure to the bottom to the meniscus.

Mass:

The amount of matter that makes up something.

Use the triple beam balance to measure for mass.

Gram (g), kilogram (Kg), milligram (mg)

Length:

How long something is.

Use the centimeter side of the ruler to measure length.

Meter (M), centimeter (cm), millimeter (mm), kilometer (Km)

Metric System:

The international system of measurement (SI) that allows people all over the world to communicate amounts.

Base Units: Liter (volume), Gram (mass), Meter (length), Celsius (temperature), Seconds (time)

Kind       Hearts       Don’t       Butcher.      d.           c.       makes                  millions

Kilo         Hecto       Deka          Base       deci       centi       milli                      micro

1,000        100          10                1           1/10      1/100       1/1,000

For conversion:

1) find where to start and locate decimal

2) find where to end

3) determine how many spaces to hop

4) hop the decimal the correct number of spaces

Example:

.001 hm = ? dm

 

We are starting at Hecto.

We will end at deci.

We will need to hop 3 spaces to the right.

The decimal will hop 3 spaces to the right.

.001hm = 1. dm

Qualitative Data:

Deals with descriptions

Can be observed but not measured

Colors, textures, smells, tastes, appearance, etc.

QUALITative—> QUALITy

Quantitative Data:

Deals with numbers

Data which can be measured

Length, height, area, volume, mass, speed, time, temperature, humidity, costs, etc.

QUANTITative—–> QUANTITy

Example:

Oil Painting

Qualitative Data- blue color, gold frame, smells musty, texture shows brush strokes, peaceful scene of the country

Quantitative Data- picture is 25 cm by 30 cm, with frame 29 cm by 34 cm, weighs 4 Kg, costs $300
