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.

Today's planning

- Introduction and icebreaking shenanigans

Chemistry:

- The macro- and microlevel

- Experiment

-Short break??

- The periodic table

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!?

Macro vs. Micro level

What do you think of when you hear the words

MACRO and MICRO?

Macro level

All things perceivable with your senses.

So....

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

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

Is this property in the macrolevel?

Is this property in the macrolevel?

Is this property in the macrolevel?

No.... because

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

Micro-level

Micro=small

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

Any questions on...

Macro-microlevel?

How do we explain things we cannot see??

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

Ever heard of Molecules??

Ever heard of Molecules??

Universe is built up from tiny tiny tiny building blocks called

Molecules.

Water consists of Water molecules

ethanol/alcohol consists of ethanol molecules

Does mayonaise consist of mayonaise molecules?

A little perspective

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

Take a guess!!

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!!!

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

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.

Grab your devices! 

go to Lessonup.com

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

What could this mean?

Any questions on:

Macro-micro level

Molecules

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!

We carry on!

"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

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!

WAIT WAIT WAIT....

So the world consists of tiny building blocks called molecules, 

but

What are molecules made of???

ATOMS

These smaller parts are called Atoms

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

Any questions on....

- The macro/micro level?

-Molecules?

-Atoms?

-The periodic table?

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!

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!?

Homework

See you all next week!!
