Content overview

There are 20 teaching chapters in total, six for each of physics, chemistry and biology, plus ideas about science and a practical skills activity.

In all three sciences, students develop their understanding of how scientific principles and concepts help describe complex and diverse natural phenomena in terms of a small number of key ideas. They also develop relevant practical skills.

Biology

The six teaching chapters are further subdivided:

  • B1: You and your genes
    • What is a genome and what does it do?
    • How is genetic information inherited?
    • How can and should gene technology be used?
  • B2: Keeping healthy
    • What are the causes of disease?
    • How do organisms protect themselves from pathogens?
    • How can we prevent the spread of infection?
    • How can lifestyle, genes and the environment affect my health?
    • How can we treat disease?
  • B3: Living together - food and ecosystems
    • What happens during photosynthesis?
    • How do producers get the substances they need?
    • How are organisms in an ecosystem interdependent?
    • How are populations affected by conditions in a ecosystem?
  • B4: Using food and controlling growth
    • What happens during cellular respiration?
    • How do we know about mitochondria and other cell structures?
    • How do organisms grow and develop?
    • Should we use stem cells to treat damage and disease?
  • B5: The human body - staying alive
    • How do substances get into, out of and around our bodies?
    • How does the nervous system help us to respond to changes?
    • How do hormones control responses in the human body?
    • Why do we need to maintain a constant internal environment?
    • What role do hormones play in human reproduction?
    • What can happen when organs and control systems stop working?
  • B6: Life on Earth - past, present, future
    • How was the theory of evolution developed?
    • How does our understanding of biology help us classify the diversity of organisms on Earth
    • How is biodiversity threatened and how can we protect it?

Chemistry

The six teaching chapters are further subdivided:

  • C1: Air and water
    • How has the earth’s atmosphere changed over time, and why?
    • Why are there temperatures changes in chemical reactions?
    • What is the evidence for climate change, why is it occurring?
    • How can scientists help improve the supply of potable water?
  • C2: Chemical patterns
    • How have our ideas about atoms developed over time?
    • What does the periodic table tell us about the elements?
    • How do metals and non-metals combine to form compounds?
    • How are equations used to represent chemical reactions?
  • C3: Chemicals of the natural environment
    • How are the atoms held together in a metal?
    • How are metals with different reactivities extracted?
    • What are electrolytes and what happens during electrolysis?

General Topics

  • BCP7: Ideas about science
    • What needs to be considered when investigating a phenomenon scientifically?
    • What conclusions can we make from data?
    • How are scientific explanations developed?
    • How do science and technology impact society?
  • BCP8: Practical skills
    • A practical-based topic which provides students with the skills required for the 15% practical content in the examinations
    • Students complete at least 16 practical activities, five in biology, five in chemistry and six in physics, and have the opportunity to use all the apparatus and techniques listed in the specification
    • This will include awareness of safety procedures and the use of appropriate scientific diagrams to record apparatus and procedures. Practical skills are embedded within all the teaching chapters.
