The practical

#### Slide 3 -Slide

The practical
Date: Monday january 21st
Materials you need:
• A protractor (geodriehoek)
• A calculator

#### Slide 4 -Slide

The practical
What do you have to know?
• How to measure volume
• How to measure mass
• How to calculate density

Measuring mass

Measuring volume

Vcylinder=πr2H

Measuring volume

#### Slide 9 -Slide

Calculating density
Cylinder
m = 565,4 g
V = 1271,7 cm3
Plier
m = 231,5 g
V = 60 cm3

#### Slide 10 -Slide

Density

Density: the amount of mass per unit of volume – kg/m3, g/cm3
Mass: the amount of matter in an object – unit: kg, g
Volume: The amount of space an object takes in – Unit: m3, cm3 , L, mL
• 1 L = 0,001 m3
• 1 mL = 1 cm3

#### Slide 11 -Slide

Checking the goals

#### Slide 12 -Slide

How do you measure mass?
How do you determine the volume of...
• A cuboide?
• A cylinder?
• An irregular object?

#### Slide 13 -Slide

Measuring mass: use a scale
Determining volume:
• cube or cuboid —> length x width x height
• Volume Cylinder —>
• Irregular shaped object —> use a measuring cylinder

#### Slide 14 -Slide

rewrite the formula
ρ=Vm
V=...
m=...

ρ=Vm
V=ρm
m=ρV
