3. Length: distance from one point to another.
unit = meter
symbol = m
instrument = meter stick.

6. 2.Volume is the amount of space an object takes up.
Liquid Volume = unit liter, symbol = L, instrument = graduated cylinder.
b. Read bottom of the meniscus curve

7. c. Volume of regular shaped objects use a metric ruler and measure the
2cm
10cm
25cm
25 X 10 X 2 = 500cm3

8. d. Volume of irregular shaped objects like stones use graduated cylinder.25 20
Volume is 5 cm3

9. 10 cm
What is the volume of this block?
4 cm
12 cm
What is the volume of water?

10. 3.Mass amount of matter an object has.
Unit = Gram
Symbol = g
Instrument = Triple Beam Balance

11. 4. Density is the amount of mass in a certain volume
4.Density is the amount of mass in a certain volume. The unit = g/ml or g/cm3
mass
volume
Density = the mass divided by the volume
Density = mass/volume
D = m/v r U M B

12. 5. Limits of measurements possible reasons for different measurements.
Human error.
Instruments can only measure to a certain level of accuracy.
There is no perfect measuring instrument.
