OUTCOME
By the end of this lesson you will be able to explain the difference between matter and antimatter. You will be able to explain what cosmic radiation is and recognise the large array of different subatomic particles and be able to identify examples of Hadrons and Leptons.
Subatomic particles come from two fundamental particles, leptons and quarks. Quarks combine to create hadrons which in turn are grouped as mesons and baryons. protons and neutrons are baryons. Electrons are leptons

1. What are fundamental particles?
2. Write out the taxonomy if the particle zoo into your notes.
3. What type of particles do quarks combine to make?
4. How are these particles related to protons and neutrons?
5. what is an anti-particle?
6. What happens when particles and antiparticles interact?
Create a cartoon strip which depicts the 4 following particles as 'personalities' with certain physical properties:
Hadrons
Leptons
Mesons
