  • Understanding what to do at the practical
  • to know how to measure volume
  • To know how to measure mass
  • To know how to calculat density

Slide 2 - Tekstslide

The practical

Slide 3 - Tekstslide

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

Slide 4 - Tekstslide

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

Slide 5 - Tekstslide

Measuring mass

Slide 6 - Tekstslide

Measuring volume

Slide 7 - Tekstslide

Vcylinder=πr2H

Slide 8 - Tekstslide

Measuring volume

Slide 9 - Tekstslide

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

Slide 10 - Tekstslide

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 - Tekstslide

Checking the goals

Slide 12 - Tekstslide

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

Slide 13 - Tekstslide

Measuring mass: use a scale
Determining volume:
  • cube or cuboid —> length x width x height
  • Volume Cylinder —>    
  • Irregular shaped object —> use a measuring cylinder
πradius2height

Slide 14 - Tekstslide

rewrite the formula
ρ=Vm
V=...
m=...

Slide 15 - Tekstslide

ρ=Vm
V=ρm
m=ρV

Slide 16 - Tekstslide
