Water

Klas 2; Periode 3; NT HAVO VWO TTO Period 3 

Rough planning

lesson 1: Section 1 + 2

Lesson 2: Section 2

Lesson 3: Section 3

Lesson 4: Section 4

Lesson 5: Grade exercise

Lesson 6: Waterpump

Lesson 7: Waterpump

Why water?

Water is everywhere

YOU are about 60% water

We need water to live (stay hydrated)

A lot op physics and chemistry is based on water

(temperature, phases, and more...)

For starters

Exercise 1, 2 and 3 are  warming up exercises.

Make them!

Use Google if needed.

Repetition

Content (inhoud)

Fluids / empty space

Volume (inhoud)

Something with mass

You may use both.

Mass (massa)

The amount of particles  

Weight (gewicht)

The net force that is pulling you to earth.

Conversion

Overlap

1 gram = 1 mL = 1 cm3 (mass to volume to volume)

1 Litre = 1 dm3 = 1kg (volume to volume to mass)

Let's work

Exercise 4

Question 1 to 10 

write down any equation you use

Density

How dense a material is 

or

'hoe dicht de deeltjes bij elkaar zitten in een stof'

Density 2

Every material has its own density

The unit for density is

g/cm3 or kg/m3

Rest of class

Finish the exercises 1 - 4

Read experiment: 'Determine the density of a liquid'

Make exercise 5

Next class

Experiment: Determine density
