Slide 10 - Open vraag

Explanation
Density
= property ...
= is a physical and chemical quantity (variable) that expresses how much mass of that substance is present in a given volume.

The mass (in grams) of 1 cm3 of a substance.

Every substance with a volume of 1 cm3  has a different mass...

Slide 11 - Tekstslide

Slide 12 - Tekstslide

Uitleg
Aluminum
Density of 2,70 g/cm3 

You pronounce this as: 2.70 grams per cubic centimeter.

If you take 1 cm3 aluminum and place it on a scale, the scale will indicate 2.70 grams

Slide 13 - Tekstslide

What will happen when you put a brick into water?
A
It sinks
B

Slide 14 - Quizvraag

What will happen when you put 'normal' wood into water?
A
It sinks
B
It hovers
C
It floats

Slide 15 - Quizvraag

Why does a brick sink and wood float?

Slide 16 - Open vraag

Explanation
Sinking / Hovering / Floating:

  • Sinking: The substance that sinks has a bigger density 

  • Hovers: The density of the substances are equal.

  • Floating: The substance that floats has a smaller density 

Slide 17 - Tekstslide

Explanation
Density of water = 1 g/cm3

If density   > 1 g/cm3 --> It sinks
If density = 1 g/cm3 --> It hovers
If density   < 1 g/cm3 --> It floats
