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

*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

Beaker *Tools used (liquid volume) – Beaker or Graduated Cylinder Units - Milliliter (ml) Liter (l) Beaker

Measuring the Volume of a *225 ml (approx) 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.

*Measuring irregular shaped objects

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)

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

Let’s Do It.
