3. mass
Measure of the amount of
matter in an object
Measured with balance
scale

4. A balance scale measures mass.

5. volume
Amount of space that matter takes up
Measured by:
 Length X Width X Height
or
 with graduated cylinder

6. density
Amount of mass in a certain
volume of matter
Mass/volume
Determines whether object
floats or sinks in water
Why Objects Float Activity

7. metric system- based on 10’s
Measured in
mass grams (g)
volume Solids- cubic centimeter(cm3
)
Liquids- milliliters (mL)
density grams/cubic cm or mL
(g/cm3
) or (g/mL)

8. Measuring tools
Measurement Tool
length metric ruler- meterstick
mass balance
temperature thermometer
volume graduated cylinder
meterstick graduated
