Biology

Curriculum Intent

Our intent is to empower students to explore and understand the wonderment of everyday life.  There are many challenges for a 21st Century Biologist, from saving threatened species and reversing climate change, to feeding the world and curing diseases.  We aim to engage students and equip them with skills allowing them to both contribute directly to advancing human understanding of life on Earth, and to make informed responses to data and opinion pieces in the media.  We focus on encouraging creativity in questioning, reflective evaluation of data and precise communication of understanding.

Biology is offered as:

  • Core subject Years 7, 8 & 9
  • GCSE Core Years 10 & 11
  • IB Years 12 & 13

Key Stage 4 Biology

Curriculum Overview

Students at Key Stage 4 have two periods a week studying GCSE Biology either as a separate AQA qualification or part of the Trilogy Combined Science qualification.

 Year 10

In “Cell Biology” students learn about cell structure and the use of microscopes, different cell types, cellular transport and cellular respiration.

In “Organisation” students learn about the digestive system, enzymes, and the circulatory and gas exchange systems, including the effect of exercise.

In “Health and disease” students learn about communicable and non-communicable diseases, including plant diseases, the body’s defences against disease and treatments for these diseases.

In “Plant biology” students learn the structure of leaves, the process and role of photosynthesis, and transport in plants.

In “Ecology” students learn about the structures of ecosystems, including element and energy flow and the role of decay.  They study the feeding relationships within an ecosystem and the adaptations of the organisms in relation to abiotic and biotic factors.  Students study practical ecology techniques.  They also learn about the effect of pollution on biodiversity and also consider positive interactions humans can have in an ecosystem.

Students will develop their practical skills through a range of tasks.

Year 11

In “Homeostasis and response” students learn about plant and human hormones.  They study the control of body temperature, blood glucose levels and water balance.  Students learn about the menstrual cycle and fertility technologies.  They also learn about the brain and the nervous system, including reflex actions and the eye.

In “Inheritance, variation and evolution” students learn about reproduction on a cellular level and the structure of DNA.  They consider how proteins are made and the effect of mutations.  Students learn to predict inheritance theoretically and study the work of pioneers of inheritance and evolutionary theories.  They consider how variation links with natural selection and the evidence to support this theory.  Finally students study biotechnologies.

Students will develop their practical skills through a range of tasks.

Assessment at GCSE

– Paper 1: 50% of qualification. 105 minute written examination in which students are required to demonstrate their knowledge and understanding of Topics 1-4 and the associated experimental and data skills.

– Paper 2: 50% of qualification. 105 minute written examination in which students are required to demonstrate their knowledge and understanding of Topics 5-7 and the associated experimental and data skills.

Year 12

In “Molecular biology” students learn about the molecules that contribute to metabolism, including the actions of enzymes and the processes of protein synthesis, respiration and photosynthesis. This is extended in the “Nucleic acids” and “Metabolism and Bioenergetics” topics for higher level students.

In “Cell biology” students learn about cell structures, origins, transport and division.

In “Human physiology” students learn about the systems of the body including the digestive, circulatory, immune, gas exchange, nervous, hormonal and reproductive systems. In higher level “Physiology” students learn about movement and the role of the kidneys, as well as extending their understanding of the immune and reproductive systems.

In “Plant biology” students learn about plant transport, growth and reproduction.

In the independent investigation, students design a protocol to investigate any biological question. They spend at least 10 hours collecting and analysing data, before evaluating their research.

Year 13

In “Ecology” students learn about ecosystems, including energy flow and carbon cycling, as well as climate change.

In “Evolution and biodiversity” students learn about natural selection, evolutionary relationships and classification.

In “Neurobiology and behaviour” students learn about neural development and the brain, and perception of stimuli, with high level students also covering innate and learned behaviour and the effect of drugs on the nervous system.

In “Genetics” students learn about the structures and processes of inheritance, including predicting inheritance patterns, and study biotechnologies. Higher level students extend these concepts and also study gene pools and speciation.
