What is everything made of? ♦A: Water ♦C: Cheese ♦B: Things called Atoms ♦D: Dirt 50:50

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 50:50

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…

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!

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 50:50

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

How many main parts does an atom have? ♦A: 1 ♦C: 3 ♦B: 2 ♦D: 4 50:50

Out of these four which one is a part of an atom? ♦A: Dust ♦C: Proton ♦B: A small stone ♦D: Zuculeron 50:50

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 50:50

Out of these four which one is a part of an atom? ♦A: New Hat ♦C: New Song ♦B: Neutron ♦D: Photon 50:50

What is the centre of an atom called? ♦A: Planet ♦C: Nucleus ♦B: Sprite ♦D: Origin 50:50

Which part whizzes round the nucleus? ♦A: Electron ♦C: Proton ♦B: Neutron ♦D: Photon 50:50

Proton Neutron Electron

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

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 + -

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

What charge does a proton have? ♦A: Negative ♦C: Hot ♦B: Neutral ♦D: Positive 50:50

Is anything smaller than an atom? ♦A: Yes ♦C: We don’t know ♦B: No ♦D: Not on earth 50:50

A proton is made from even smaller parts. What are they called? ♦A: Quarks ♦C: Photons ♦B: Neutrinos ♦D: Beutons 50:50

How many of these tiny parts are inside a proton? ♦A: 1 ♦C: 3 ♦B: 2 ♦D: 4 50:50

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

How did scientists find out about quarks? ♦A: Deep inelastic scattering ♦C: Electrolysis ♦B: Rutherford experiment ♦D: Brownian motion 50:50

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