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
♦C: With a microscope
♦B: With a magnifying glass
♦D: They are too small to see

Out of these four which one is a part of an atom?
♦A: Dust

♦B: A small stone
♦D: Zuculeron

Out of these four which one is a part of an atom?
♦A: Electron
♦C: Small Bit of Glass
♦B: Neutrino
♦D: A drop of water

Out of these four which one is a part of an atom?
♦A: New Hat
♦C: New Song
♦B: Neutron
♦D: Photon

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

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

A proton is made from even smaller parts. What are they called?
♦A: Quarks
♦C: Photons
♦B: Neutrinos
♦D: Beutons

Quarks
If I could cut a proton open I would see three parts; these are called QUARKS

How did scientists find out about quarks?
♦A: Deep inelastic scattering
♦C: Electrolysis
♦B: Rutherford experiment
♦D: Brownian motion

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