• GCSE Science equal assessment weighting of
  Science Explanations and Ideas about Science
• Links between modules
• within and across subject areas
• identifying links
• possibility of over-teaching

P2 Radiation and life

• Ideas about Science
• Distinction between correlation and cause (IaS2)
  is introduced in Module C1 Air quality, e.g
  Activity AC1.20 When do hay fever symptoms
  appear? (the hay fever / ice cream activity).
• The big Idea about Science in Module P2 is risks
  and benefits, in the context of the
  electromagnetic spectrum.
• See for example Activity AP2.15 A safe place to
  live?
• Science Explanations
• Module P2 introduces the electromagnetic spectrum
  in terms of photons.
• The electromagnetic spectrum is taken up again in
  module P6 The wave model of radiation.

B1 You and your genes

• Ideas about Science
• This module is the first introduction to ethical
  decision-making
• Big idea is outlining basic framework which can
  be used to discuss ethical decision-making
  throughout the course
• Decision-making throughout the course covers
  personal, socio-scientific and government policy
  examples.
• Science Explanations
• Inheritance is treated in terms of genes in B1
  You and your genes and DNA in the Additional
  Science module B5 Growth development

C3 Food matters IaS6 Making decisions (personal,
cost/benefit analysis, government
regulation)
C2 Material choices IaS6 Making decisions
(cost/benefit analysis)
P2 Radiation and life IaS6 Making decisions
(personal ? society)
B5 Growth and development SE cell cycle,
mitosis/meiosis protein synthesis, stem
cells, meristems, gene switching plant growth
B1 You and your genes IaS6 Making decisions
(personal, frameworks)
B1 You and your genes SE variation,
fertilization, gene (dominant/recessive), gender,
asexual reproduction, cloning (stem cells)
B3 Life on Earth SE natural selection,
mutation, evolution
