What do you have to know?

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

Slide 5 - Slide

Measuring mass

Slide 6 - Slide

Measuring volume

Slide 7 - Slide

V^{​ c y l i n d e r ​ ​} = π \cdot r^{​ 2 ​ ​} \cdot H

Slide 8 - Slide

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

D e n i s t y = \frac{​ m a s s ​ ​}{​ V o l u m e ​}

ρ = \frac{​ m ​ ​}{​ V ​}

(3 = \frac{​ 6 ​ ​}{​ 2 ​})

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

π \cdot r a d i u s^{​ 2 ​ ​} \cdot h e i g h t

Slide 14 - Slide

rewrite the formula

ρ = \frac{​ m ​ ​}{​ V ​}

V = . . .

m = . . .

Slide 15 - Slide

ρ = \frac{​ m ​ ​}{​ V ​}

V = \frac{​ m ​ ​}{​ ρ ​}

m = ρ \cdot V
