Work in pairs or alone

Speak English

In your notebooks

Group the concepts

Give each group a name

Discuss in English

Extension

Go through the study planner and make 3 lists:

1. I know this already

2. I know this a bit - I'd like to know more

3. I don't know this yet

What do think of?
5 concepts

Which elements from the period system do you know already?

Homework

Study elements handout gases

Read page 101, 102, 103 about the composition of air. (to get an idea of applications)

Bring 2 pieces of thick paper size A4 or one larger piece, a 30 cm ruler, coloured pens and scissors. (we are going to learn how to study elements)

Read study planner.

Make flash cards for the elements

Take a piece of thick paper or think cardboard.

Make cards of 4 x 4 cm.

On the one side you write the symbol.

On the other side you write the name in English at the top and in Dutch at the bottom. Work as neatly as possible.

Elements

States of matter

What is the symbol of Argon?

What is the symbol of Stikstof?

What is the Dutch name of Hydrogen?

What is the element with the symbol Ne?

Elements Study Tips

Start a symbol with a capital letter to distinguish a new element.
Example: CO = carbon monoxide; Co = cobalt

Study the elements with one letter separately from the ones with two letters.

Eg. C = carbon, Ca = calcium

Place confusing elements/symbols in a separate list.

Eg. N = nitrogen / stikstof; S = sulphur / zwavel

Eg. Au, Ag, Ar, Al, Si

Strategies for answering
Try to find out questions

1. make sure to know what all words mean

2. find a knowledgeable person in your network (inc. yourself)

3. look up keywords on internet

Extra notes on states of matter

Whipped cream = foam = mixture of liquid (cream) and gas (nitrous oxide or air). See also page 57.

If you have a question about the homework write it here.

Homework

Study elements handout gases, metals in mobiles and other precious metals.

Read page 32 (no questions), 33, 34, answer questions and check them in Magister

What is the symbol of Iron/ijzer?

What is the symbol of Silver?

What is the English name of Silicium?

What is the element with the symbol Al?

How can you recognise a metal?
Which physical properties typify a metal?

Properties metals

    Good electrical conductors and heat conductors.

    Malleable = can be beaten into thin sheets.

    Ductile = can be stretched into wire.

    Possess metallic luster = shiny when polished

    Opaque (not transparant) as thin sheet.

    Solid at room temperature (except Hg).

Homework

Read page 35, 36, answer questions and check them in Magister.

Study elements handout gases, metals in mobiles and other precious metals, heavy metals/ metals in batteries.

Today we will learn ...

... what the properties are of the different states of matter.

... what happens during phase changes = state changes.

How? Using 3 games played in groups of 3.

Time? 15 minutes task 1 & 2; 15 min task 3 = 30 min total.
including checking answers on answer sheet.

Need help with the content? Use p. 33, 34, 38 and 49 from your book.

Need help with the game? Ask class mates or the teacher.

When you are done? Write down in your notebook what you have learnt.

Why do gases spread quickly?

Why do solids keep their shapes?
Use the words you just dragged.

gas

solid

close together

changing places

tightly held together

far apart

Diffusion and Effusion

Diffusion = the way gases and liquids spread out to occupy all the available space moving from high concentration to low concentration.

Effusion = the way gases and soluble particles move through small holes due to their small size.

Molecules move through a substance.
In which state of matter should the substance be
for the molecules to move fastest.
Why?

1. Gas
2. Liquid
3. Solid
4. I don't know
