Learn about the symbols from the english speaking movie below:

Draw them on cards with the symbol on one side and the explaining text on the other side.

Now you can look on one side and try to remember what the symbol means or vice versa.

Atom is a basic buidling block of matter. This doesn't mean that there are no smaller particles than atom, but only atom is stable enough to exist on its own indepently or in a combination with other atoms in a molecul.

This very nice video gives more detailed info on the topic of atoms.

What is a molecul? A molecul would be a combination of different atoms in differen numbers and variations, bonded together. A good example for this is water with a chemical formula H2O, meaning the molecul of water is made of two atoms of hydrogen (H) and one atom of oxygen (O).

Find information and answer these questions

Right or wrong… about air

1. Air is the same as oxygen

2. Air is a mixture of different gases

3. If you have a cold, tour ears will pop

4. Cold air rises

5. Air cotains water vapor

6. In winter, the skin may become dry. It’s because the air lacks moisture

7. We breathe the same air as Julius Ceasar and Elvis

8. On high mountains, the air is thin

9. Air is completely harmless to humans

10. The air in a very small town is as polluted as in Los Angeles

Discuss:

How long can you survive without air in space?

What do you know about the greenhouse effect?

Does air weigh anything?
