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 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

50:50

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

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

♦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

QuarksIf 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

50:50

Deep inelastic scatteringIf we fire very fast electrons at

protons or neutrons we can detect the parts inside. These parts are called quarks.
