Life & Health Sciences study guides

A guide to the CCEA Life and Health Sciences A2 1 Investigative Project portfolio unit: how it is internally assessed, how to develop a research question and null hypothesis, plan an extended valid investigation, statistically analyse data, draw conclusions, evaluate critically and reference sources.

A deep-dive CCEA Life and Health Sciences guide to the externally assessed A2 2 Organic Chemistry unit. Covers functional groups and nomenclature, the reactions of the main organic families, structural and stereoisomerism, instrumental analysis, and addition and condensation polymers, with the skills CCEA examines.

A deep-dive CCEA Life and Health Sciences guide to the externally assessed A2 5 Genetics, Gene Technology and Stem Cells unit. Covers DNA and protein synthesis, inheritance and genetic crosses, gene technology and PCR, stem cells and cloning, and mutations and genetic disease, with the skills CCEA examines.

A guide to the CCEA Life and Health Sciences AS 1 Experimental Techniques portfolio unit: how it is internally assessed, how to plan a fair test, control variables and risk, process data with units, significant figures and uncertainty, present results, and write a high-mark evaluation.

A deep-dive CCEA Life and Health Sciences guide to the externally assessed AS 2 Human Body Systems unit. Covers the cardiovascular system, the respiratory system, respiration, homeostasis and monitoring, the musculoskeletal system, and nutrition and exercise, with the structure-and-function links CCEA examines.

A deep-dive CCEA Life and Health Sciences guide to the externally assessed AS 3 Aspects of Physical Chemistry in Industrial Processes unit. Covers rates of reaction and energetics, chemical equilibria, acids, bases and pH, the Haber and Contact processes, and redox and electrolysis, with the calculations CCEA examines.
