How loud an object sounds
How much space an object takes up
How much mass is in a given amount of space
*Defend your answer and write it on the White Board.

2. Lesson Title: Measuring Volume (Pg 7)
Volume - How much space an object takes up

3. *Square/Rectangular objects are measured:
Length (L) x Width (W) x Height (H) W H L
10 cm x 2 cm x 4 cm = 80 cm³

Measuring the Volume of a
Liquid Substance
*When measuring in a beaker, make sure you read the measurements from smallest (bottom) to largest.
*If the liquid level is between numbers, you must estimate the value of the measurement.

12. *Measuring irregular shaped objects

13. How do we measure volume?
*Water Displacement – Change in the volume of water
Starting water level = 19 ml
Ending water level = 29 ml
Volume = 10 ml (29 – 19)

14. *Water Displacement
Starting water level = 64 ml
Ending water level = 68 ml
Volume = 4 ml (68 – 64)
