University of Plymouth Faculty of Education PGCE (Secondary) Programme Science Pathway Subject Knowledge Profile Trainee Teacher ………………………………… 140821 Secondary Science PGCE (Biology, Chemistry & Physics) Science Subject Knowledge Profile This document is not a test but a method of managing an ongoing audit of you knowledge. There are sections for: key stage 3 - From the key stage 3 National Curriculum to be used in all maintained schools from Sept 2014. key stage 4 – Indicative content based on exam specifications. You will also need to refer to the specification used by your placement schools by downloading it from the examboard website. www.aqa.org.uk; www.edexcel.org.uk; www.ocr.org.uk. Key stage 5 – From DfE ‘GCE AS and A level subject content’, published April 2014. Instructions for completing the subject knowledge profile Some sections are designed to be completed using a traffic lighting system; Green (competent), Amber (unsure) or Red (area to work on), or use . These sections must be revisited at the indicated times. The traffic lighting asks you to audit your subject knowledge SK (how well you know the concepts) and also your pedagogical content knowledge PCK (how well do you know how to teach those concepts). You are not asked to audit your PCK until after your first placement. You are also asked to record examples of lessons/topics which involve ‘Working Scientifically’ in key stage 3 lessons. You do not need to list every lesson, which incorporates a particular skill but should have a few examples (approx. 3) for each one. Most trainees should only audit their key stage 5 specialism. Some people may wish to complete more than one, such as trainees that have completed a subject knowledge enhancement course. Those trainees must complete the subject they enrolled on but should also attempt to complete their ‘first’ degree subject. 2|Page Secondary Science PGCE (Biology, Chemistry & Physics) Initial Review of ‘Post Interview-Pre PGCE’ preparation Complete the following table by stating the subject knowledge you were asked to work on at interview and remedial tasks completed since then Areas for development Work attempted since interview (Including texts/sources/resources used) 3|Page Secondary Science PGCE (Biology, Chemistry & Physics) Key Stage 3 Pedagogical Knowledge by end of PT2 Pedagogical Knowledge by Easter Pedagogical Knowledge by end of DSP SK by end of PT1 SK at end of T&L KS3 Range & Content Subject knowledge at start of induction Range & Content Subject content – Biology Pupils should be taught about: Structure and function of living organisms Cells and organisation cells as the fundamental unit of living organisms, including how to observe, interpret and record cell structure using a light microscope the functions of the cell wall, cell membrane, cytoplasm, nucleus, vacuole, mitochondria and chloroplasts the similarities and differences between plant and animal cells the role of diffusion in the movement of materials in and between cells the structural adaptations of some unicellular organisms the hierarchical organisation of multicellular organisms: from cells to tissues to organs to systems to organisms.

The drug was then banned, but more recently is being used successfully to treat leprosy. The overall impact of legal drugs on health is much greater than the impact of illegal drugs, because far more people use them. Drugs change the chemical processes in people’s bodies so that they may become dependent or addicted to them and suffer withdrawal symptoms without them. Heroin and cocaine are very addictive. Nicotine is the addictive substance in tobacco smoke. Tobacco smoke contains carcinogens. Tobacco smoke also contains carbon monoxide which reduces the oxygen-carrying capacity of the blood. In pregnant women this can deprive a foetus of oxygen and lead to a low birth mass. Alcohol affects the nervous system by slowing down reactions and helps people relax, but too much may lead to lack of self-control, unconsciousness or even coma, eventually damaging the liver and brain. 27 | P a g e Pedagogical Knowledge by end of PT2 Pedagogical Knowledge by Easter Pedagogical Knowledge by end of DSP SK by end of PT1 SK at end of T&L Examples of the range and content from the AQA, OCR 21st Century Science & OCR Gateway specifications Subject knowledge at start of induction Secondary Science PGCE (Biology, Chemistry & Physics) Defining and using the terms; atom, element, compound, molecule, mixture, atomic mass and atomic number.

The living world can be studied at population, organism, cell and molecular levels. There are fundamental similarities as well as differences between plants, animals and micro-organisms. Biodiversity the variety of life, both past and present, is extensive, but the biochemical basis of life is similar for all living things biodiversity refers to the variety and complexity of life and may be considered at different levels 37 | P a g e Pedagogical Knowledge by end of PT2 Pedagogical Knowledge by Easter Pedagogical Knowledge by end of DSP SK by end of PT1 SK at end of T&L Topics Subject knowledge at start of induction Secondary Science PGCE (Biology, Chemistry & Physics) biodiversity can be measured, for example within a habitat or at the genetic level classification is a means of organising the variety of life based on relationships between organisms and is built around the concept of species originally classification systems were based on observable features but more recent approaches draw on a wider range of evidence to clarify relationships between organisms adaptations of organisms to their environments can be behavioural, physiological and anatomical adaptation and selection are major factors in evolution and make a significant contribution to the diversity of living organisms Exchange and transport organisms need to exchange substances selectively with their environment and this takes place at exchange surfaces factors such as size or metabolic rate affect the requirements of organisms and this gives rise to adaptations such as specialised exchange surfaces and mass transport systems substances are exchanged by passive or active transport across exchange surfaces the structure of the plasma membrane enables control of the passage of substances into and out of cells Cells the cell theory is a unifying concept in biology prokaryotic and eukaryotic cells can be distinguished 38 | P a g e Pedagogical Knowledge by end of PT2 Pedagogical Knowledge by Easter Pedagogical Knowledge by end of DSP SK by end of PT1 SK at end of T&L Topics Subject knowledge at start of induction Secondary Science PGCE (Biology, Chemistry & Physics) on the basis of their structure and ultrastructure in complex multicellular organisms cells are organised into tissues, tissues into organs and organs into systems during the cell cycle genetic information is copied and passed to daughter cells daughter cells formed during mitosis have identical copies of genes while cells formed during meiosis are not genetically identical Biological molecules biological molecules are often polymers and are based on a small number of chemical elements in living organisms nucleic acids (DNA and RNA), carbohydrates, proteins, lipids, inorganic ions and water all have important roles and functions related to their properties the sequence of bases in the DNA molecule determines the structure of proteins, including enzymes enzymes catalyse the reactions that determine structures and functions from cellular to wholeorganism level enzymes are proteins with a mechanism of action and other properties determined by their tertiary structure enzymes catalyse a wide range of intracellular reactions as well as extracellular ones ATP provides the immediate source of energy for biological processes Ecosystems ecosystems range in size from the very large to the very small biomass transfers through ecosystems and the efficiency of transfer through different trophic levels can 39 | P a g e Pedagogical Knowledge by end of PT2 Pedagogical Knowledge by Easter Pedagogical Knowledge by end of DSP SK by end of PT1 SK at end of T&L Topics Subject knowledge at start of induction Secondary Science PGCE (Biology, Chemistry & Physics) be measured microorganisms play a key role in recycling chemical elements ecosystems are dynamic systems, usually moving from colonisation to climax communities in a process known as succession the dynamic equilibrium of populations is affected by a range of factors humans are part of the ecological balance and their activities affect it both directly and indirectly effective management of the conflict between human needs and conservation help to maintain sustainability of resources Control systems homeostasis is the maintenance of a constant internal environment negative feedback helps maintain an optimal internal state in the context of a dynamic equilibrium.
