More importantly though...

Who are you guys?

You get 30 seconds to think of one thing you'd like tell me about yourself!

Inspiration:

Your favourite dish, Your favourite game, Your favourite sport, etc.

Slide 3 - Slide

Today's planning

- Introduction and icebreaking shenanigans

Chemistry:

- The macro- and microlevel

- Experiment

-Short break??

- The periodic table

Slide 4 - Slide

Today you will learn:

- What is the macrolevel?

- What is the microlevel?

- What are molecules and atoms?

- What is the periodic table?

-Why do these things matter!?

Slide 5 - Slide

Macro vs. Micro level

What do you think of when you hear the words

MACRO and MICRO?

Slide 6 - Slide

Macro level

All things perceivable with your senses.

So....

All things you can see, smell, feel, hear, taste

Slide 7 - Slide

So..... A little game.....

Slide 8 - Slide

Is this property in the macrolevel?

Slide 9 - Slide

Is this property in the macrolevel?

Slide 10 - Slide

Is this property in the macrolevel?

Slide 11 - Slide

No.... because

You cannot see,smell,hear from just the substances that they have these properties

Slide 12 - Slide

Micro-level

Micro=small

Slide 13 - Slide

We can see a plant is green...

But we cannot see what the leafs of a plant consist of that MAKE it green

macro properties are explained by micro-concepts

Slide 14 - Slide

Any questions on...

Macro-microlevel?

Slide 15 - Slide

How do we explain things we cannot see??

The Universe must be built from smaller pieces that explain this!

Slide 16 - Slide

Ever heard of Molecules??

Slide 17 - Slide

Ever heard of Molecules??

Universe is built up from tiny tiny tiny building blocks called

Molecules.

Slide 18 - Slide

Water consists of Water molecules

ethanol/alcohol consists of ethanol molecules

Does mayonaise consist of mayonaise molecules?

Slide 19 - Slide

A little perspective

How many molecules of water are in a glass of water?

Take a guess!!

Slide 20 - Slide

A little perspective

How many molecules of water are in a glass of water?

6.7septillion!!

6.700.000.000.000.000.000.000 molecules!!!

Slide 21 - Slide

There's more water molecules in a glass of water, then there are glasses of water in all of the oceans on earth!

Slide 22 - Slide

Molecules are so small.....

Why do they matter?? We can't see them anyway....

We can explain a compound's properties by identifying the molecules they consist of.

Slide 23 - Slide

Grab your devices!

go to Lessonup.com

Slide 24 - Slide

Draw what you think molecules
of water in a glass look like!

Slide 25 - Open question

What could this mean?

Slide 26 - Slide

Any questions on:

Macro-micro level

Molecules

Slide 27 - Slide

Time for a short break?

You have 10 minutes to stretch your legs, leave the classroom if you like, grab something to eat/drink, ask questions

Shall we arrange something fun?

If all of you are back in time, I'll show something cool!

If someone is not.... I'll keep it for next week!

Slide 28 - Slide

We carry on!

Slide 29 - Slide

"We can explain a compound's properties by identifying the molecules they consist of."

The molecules tell us whether a compound is acidic or basic

Slide 30 - Slide

Scientists have learned that

If you light gasoline(Benzine) on fire, CO2 and H2O molecules form

but if you burn alcohol, CO2 and H20 molecules are also the products

So apparently, gas and alcohol molecules consist of the same parts, but in different formation!

Slide 31 - Slide

WAIT WAIT WAIT....

So the world consists of tiny building blocks called molecules,

but

What are molecules made of???

ATOMS

Slide 32 - Slide

These smaller parts are called Atoms

All the different types of atoms are in a scheme called the Periodic table of Elements

Slide 33 - Slide

Slide 34 - Slide

Any questions on....

- The macro/micro level?

-Molecules?

-Atoms?

-The periodic table?

Slide 35 - Slide

Final assignment

Choose one element in the periodic table and teach the class something about that element!

Example of what to do:

I choose Potassium(Kalium in dutch)!

It's symbol on the periodic table is K.

Our primary source of Potassium is found in bananas!

Slide 36 - Slide

Have you learned:

- What is the macrolevel?

- What is the microlevel?

- What are molecules and atoms?

- What is the periodic table?

-Why do these things matter!?
