3. Everything around us is made from Atoms

4. 50:50 How big are these atoms? A: Very big
B: The same size as a football

5. Atoms are nearly the smallest things on earth
Imagine a block of wood
I cut the wood into 8 pieces
And then 32 pieces
And so on…

6. Eventually, when I could not cut the wood into smaller pieces and I had a really good knife I would get to the smallest bit of wood. An atom. An atom is so small it is metres wide!

7. 50:50 How do we look at atoms? A: Just with our eyes
B: With a magnifying glass
C: With a microscope
D: They are too small to see

8. They’re so small, not even the most powerful microscope can seen them!

16. Charge
This is a magnet:
It has a positive end
And a negative end

17. + - This is like an Atom One part is Positive This is the Proton
Another part in negative
This is the electron
The last part has no charge
This is the Neutron + -

18. 50:50 How do we show charge? A: Positive and Negative B: Up and Down
C: In and out
D: Black and White

25. Deep inelastic scattering
If we fire very fast electrons at
protons or neutrons we can
detect the parts inside. These parts are
called quarks. - +
