									                          Topic – Physics 2a
                                                                Thursday 4th February




          Title:Alpha, Beta, Gamma
                   Radiation
•   Prior learning
     – Most atoms are stable
     – Some naturally occurring atoms are unstable and emit radiation
     – This causes atom to change into different element or particle.



•   Key words
     – Atom, proton, neutron, atomic number, mass number, isotope, radioactive.
               Topic – Physics 2a
           Alpha, Beta, Gamma
                Radiation
 By the end of this lesson we should be able to:

• Describe structure of alpha beta and gamma
  particles
• Draw diagrams to show penetration of alpha
  beta and Gamma particles
• Explain decay of Alpha, beta and gamma
  particles.
      Topic – Physics 2a

Starter: Match the symbol

•ß

•γ

•α
            Topic – Physics 2a

 Task 1: Make notes on each
type of radiation pg 164/165
• Include:
   – Symbol for decay (include numbers)
   – What the particle consists of?
   – Example of this particle
   – Diagram to show decay
   – What happens to parent nucleus once
     particle has been emitted?
   – What is conserved?
       Topic – Physics 2a

Task 2: Demo of penetration
          power
                  Topic – Physics 2a
       Task 3: Draw and explain
