Date: Thursday january 16th

Materials you need: 

• A protractor (geodriehoek)
• A calculator

The practical

What do you have to know?

• How to measure volume
• How to measure mass
• How to calculate density

The formula for density?

The formula for density

Density=​Volume​​mass​​

Measuring mass

Measuring volume

V​cylinder​​=π⋅r​2​​⋅H

Measuring volume

Calculating density

Density=​Volume​​mass​​

Calculating density

Density=​Volume​​mass​​

ρ=​V​​m​​

Checking the goals

How do you measure mass?

How do you determine the volume of...

• A cuboide?
• A cylinder?
• An irregular object?

Measuring mass: use a scale

Measuring volume:

• cube or cuboid —> length x width x height
• Volume Cylinder —>    
• Irregular shaped object —> use a measuring cylinder

π⋅radius​2​​⋅height

rewrite the formula

ρ=​V​​m​​

V=...

m=...

ρ=​V​​m​​

V=​ρ​​m​​

m=ρ⋅V
