Variation (differences within species)

This unit examines variation within species, both continuous and discontinuous, using measurements and graphical representations. It also emphasises objectivity, accuracy, precision, and repeatability in investigations, the use of appropriate techniques, and the effective presentation of data.

  • Impacts of diet, exercise and lifestyle on the body.
  • Heredity as the process by which genetic information is transmitted from one generation to the next.
  • A simple model of chromosomes, genes and DNA in heredity.

Source curriculum references

  • Pay attention to objectivity and concern for accuracy, precision, repeatability and reproducibility
  • Ask questions and develop a line of enquiry based on observations of the real world, alongside prior knowledge and experience
  • Use appropriate techniques, apparatus, and materials during fieldwork and laboratory work, paying attention to health and safety
  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Present observations and data using appropriate methods, including tables and graphs
  • Identify further questions arising from their results
  • Understand and use SI units and IUPAC (International Union of Pure and Applied Chemistry) chemical nomenclature
  • The variation between individuals within a species being continuous or discontinuous, to include measurement and graphical representation of variation
