Everything around us is made from Atoms

How big are these atoms?
♦A: Very big
♦C: Very, very, very small
♦B: The same size as a football ♦D: The size of an ant

Atoms are nearly the smallest things on earth
Imagine a block of woodI cut the wood into 8 piecesAnd then 32 piecesAnd so on…

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 0.000000001metres wide!

How do we look at atoms?
♦A: Just with our eyes

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

ChargeThis is a magnet:
It has a positive end
And a negative end
![Page 17: What is everything made of?](https://reader035.vdocuments.us/reader035/viewer/2022081802/56815d93550346895dcbae3b/html5/thumbnails/17.jpg)
This is like an Atom
One part is PositiveThis is the Proton
Another part in negativeThis is the electron
The last part has no chargeThis is the Neutron

Deep inelastic scatteringIf we fire very fast electrons at
protons or neutrons we can detect the parts inside. These parts are called quarks.
