1. I. MEASUREMENTS A. ALL MEASUREMENTS MUST HAVE TWO PARTS 1. A NUMBER
– TELLS HOW MUCH IS BEING MEASURED
2. A UNIT
– TELLS WHAT IS BEING MEASURED
EX: 1
gram 50
seconds
mass
time

2. A. Base Units – a unit based on an object or
event in the physical world.
B. Derived units – unit defined from a
combination of several base units
ex: Density = mass / volume
units: g / L

3. Distance- the measure between two points
Unit = meter (m)
Instrument = ruler, meter stick, measuring tape
A B
longer distance
C D
shorter distance

4. Time- the measure of the interval between two events
Unit = seconds (sec)
Instrument- watch, stopwatch

5. Mass- the measure of the amount of material in an object
Unit = gram (g)
Instrument- balance
less mass
more mass
more mass
less mass

6. Volume- the amount of space an object occupies
Unit = Liter (L) or
cubic centimeters (cm³) or (cc)
Instrument- graduated cylinder or ruler
Formula: V = l x w x h (cube, rectangular prism)

7. Density- the measure of the amount of mass in a given volume
Unit = grams or grams (g/L or g/cm³)
liter cm³
D = mass
volume
Instrument- balance and graduated cylinder

8. Temperature- the amount of energy in the particles of a substance
Unit = degrees Celsius (°C) ,
Fahrenheit (°F), Kelvin (K)
Instrument- thermometer
K = 273 -°C °F = °C(1.8)+32
°C = 273+K °C = °F-32
(1.8)

9. Area- the measure of the surface of an object
Unit = centimeters squared (cm²)
Instrument- ruler
A = l x w (square, rectangle)
A = pr (circle)
outside of outside shell
balloon of egg
