Biology

Overview

The International A-Level Biology curriculum follows the Pearson Edexcel specification, developing understanding of living systems from molecules and cells to organisms and ecosystems. The International Advanced Subsidiary units cover biological molecules, diet, transport, health, cells, development, biodiversity and conservation. Further units explore energy, the environment, microbiology, immunity, respiration, coordination and gene technology. Across six externally examined units, students connect biological concepts with practical investigation and real-world issues, preparing for further study and careers in biology and related fields.

 

Curriculum Goals

By the end of this course, students will be able to:

  • Explain biological concepts and the relationships between molecular, cellular, organismal and ecological processes.
  • Apply biological knowledge to familiar and unfamiliar contexts, including health, conservation and biotechnology.
  • Plan and carry out safe investigations, controlling variables and collecting reliable evidence.
  • Analyse biological data using appropriate mathematical and statistical techniques.
  • Evaluate scientific evidence, experimental methods and the ethical implications of biological applications.
  • Communicate reasoned scientific explanations and develop confidence in independent study.

 

Key Skills Developed

  • Practical and Investigative Skills: Experience through 18 core practical activities; selecting apparatus; assessing risks; testing hypotheses; recording observations; evaluating uncertainty and improving methods.
  • Mathematical and Data Analysis Skills: Calculations, graph interpretation, ecological sampling and statistical testing; identifying patterns and drawing valid conclusions from biological evidence.
  • Scientific Communication and Research Literacy: Accurate biological terminology; clear explanations and arguments; critical reading of scientific articles; use of digital tools and correctly cited sources.
  • Critical Thinking and Ethical Awareness: Evaluating evidence and alternative explanations; considering social and ethical issues in genetic screening, conservation and the use of living organisms.
