2. Collect information to find out how penicillin was developed .

3. PLAN
Introduction-Restate the question and state that there were many factors involved in the development of penicillin.
Paragraph 1- Fleming’s discovery and its limitations also state why it was not mass produced by him.
Paragraph 2- Florey and Chain’s contribution to the development of penicillin and its mass production.
Conclusion- Explain why it took a long time to mass produce penicillin.

4. Mark scheme LEVEL 1 (1-4 marks) Simple statement = Grades G/F
Generalised comment with little supporting evidence.
Example – Penicillin needed lots of expensive equipment to be mass produced.
LEVEL 2 (5-8 marks) Developed statement = Grades E/D/C
Describes the work of Fleming in London, or Florey and Chain at Oxford, or describe factor(s) affecting the mass production of penicillin.
Example – Describes Fleming’s discovery of penicillin or the work of Florey and Chain; or describes the failure of Fleming’s attempt to get funding and the availability of government funding during the war.
MAX 7 MARKS for answers which do not describe additional aspects to those in the bullet points. For example, funds from government.
LEVEL 3 (9-12 marks) Analysis = Grades B/A/A*
Explains the factors which hindered the mass production of penicillin at an earlier time in Britain and shows how the combination of factors made it possible for penicillin to be mass produced during the Second World War.
Example – Explains why Lister or Fleming did not develop penicillin and explains the factors leading to Florey and Chain’s success.
MAX 10 MARKS for answers which do not describe additional aspects to those in the bullet points. Eg, the role of government or war.
