University of Plymouth Faculty of Education PGCE (Secondary) Programme Science Pathway Subject Knowledge Profile Trainee Teacher ………………………………… 090921 Secondary Science PGCE (Biology, Chemistry & Physics) 2|Page Secondary Science PGCE (Biology, Chemistry & Physics) Science Subject Knowledge Profile Curriculum aims Learning and undertaking activities in science contribute to achievement of the curriculum aims for all young people to become: • successful learners who enjoy learning, make progress and achieve • confident individuals who are able to live safe, healthy and fulfilling lives • responsible citizens who make a positive contribution to society. The importance of science The study of science fires pupils’ curiosity about phenomena in the world around them and offers opportunities to find explanations. It engages learners at many levels, linking direct practical experience with scientific ideas. Experimentation and modelling are used to develop and evaluate explanations, encouraging critical and creative thought. Pupils learn how knowledge and understanding in science are rooted in evidence. They discover how scientific ideas contribute to technological change – affecting industry, business and medicine and improving quality of life. They trace the development of science worldwide and recognise its cultural significance. They learn to question and discuss issues that may affect their own lives, the directions of societies and the future of the world. Instructions for completing the subject knowledge profile Please refer to the course handbook (PH 4.3) but please remember this is not a test but an audit. The audit is completed in a number of stages. You should audit your knowledge at the start of the course, then update the audit with the help of the school subject mentor and your tutor as you gain experience in observations and teaching. Subject specific instructions The key stage 3 and 4 programmes of study are intentionally minimalist documents. They have been designed to be ‘fleshed out’ (developed and contextualised) within schools and by exam boards. Therefore, it is imperative that you complete the examples you encounter for each section. Please use a traffic lighting system Green (competent), Amber (unsure) or Red (area to work on), or use . This document contains key stage 5 biology, chemistry and physics. Most trainees should only audit their 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 Range & Content Traffic lighting during PT2 Traffic lighting during T&L2 Traffic lighting during T&L1 Examples Traffic lighting during induction KS3 Range & Content Energy, electricity and forces a energy(This includes the properties and behaviour of light and sound, renewable energy resources and emerging technologies such as fuel cells) can be transferred usefully, stored, or dissipated, but cannot be created or destroyed. b forces are interactions between objects and can affect their shape and motion (This includes pressure effects, linear motion and turning moments). c electric current in circuits (This includes current and voltage in series and parallel circuits) can produce a variety of effects (Electrical devices are designed to make use of a variety of effects caused by electrical currents, including heating, chemical changes and magnetic effects).

Drugs can be beneficial but may harm the body. Thalidomide is a drug that was developed as a sleeping pill. It was also found to be effective in relieving morning sickness in pregnant women. However, it had not been tested for this use. Unfortunately, many babies born to mothers who took the drug were born with severe limb abnormalities. 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. 14 | P a g e Traffic lighting during PT2 Traffic lighting during T&L2 Examples of the range and content from the AQA, OCR 21st Century Science & OCR Gateway specifications Traffic lighting during T&L1 Range & Content from key stage 4 programme of study Traffic lighting during induction Secondary Science PGCE (Biology, Chemistry & Physics) Tobacco smoke also contains carbon monoxide which reduces the oxygencarrying capacity of the blood.
