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
