Physics at Bullers Wood Relevant...challenging...and fun! Induction Day - 26th June 2014 Why Choose Physics? Physics is demanding. It is one of the most challenging A-levels that you could choose...but it is also one of the most rewarding subjects that you could study and one of the most respected! People who study Physics develop skills that are transferrable to other subjects and used in many different careers. Physicists are fantastic thinkers. They are logical and rational. They are able to synthesise information from different sources. They have a good understanding of the importance of uncertainty, in order to make good sense of data. Whatever career path you take, the skills that you learn now will be valuable throughout your life. We hope that you will enjoy it, too! This information pack is to give you some background information about the A-level Physics course and to set out the work that you are expected to complete during the holidays. 1 Course Structure Each week you will have six 50 min Physics lessons including a weekly ‘seminar-style’ Problem Solving Class, where you will have the chance to work through exam questions and resolve any problems from the lessons. Unit Title Unit 1 Physics on the go Unit 2 Physics at work Unit 3 Exploring physics Assessment method Exam Exam Practical % overall grade 40% 40% 20% In addition to this, you will do a ‘Language of Physics’ unit that will run during the Autumn term. The purpose of these lessons will be to develop skills relevant across all Physics units, improve your existing experimental skills and techniques and provide a good foundation for the preparation for the practical coursework in Unit 3. The Physics course requires a lot of independent learning. In order to be successful, the time spent working on your Physics independently should be at least equal to the time spent in the classroom. The earlier you get into this habit, the better! Physics Skills It is our aim, through a range of activities and experiments, to develop your skill levels in the areas of: • • • • • Thinking Problem solving Applying Analysing and evaluating Practical aptitude Oh, and we’ll teach you some Physics along the way too!! 2 Advice from previous Physics students Learn the GCSE topics really well. Take Physics if you like it; don't be forced into it. You have to be prepared to put in the work. Do your own work + questions at home, as well as learning everything as Get revision guides right at the beginning so you are constantly revising, it will pay off when the exams come round. you go along. Try to understand the work, not just learn it by rote - it helps your knowledge and understanding of Physics if you apply it to the outside world. Look at the course before you start. The specification is on the Edexcel website. Interesting, entertaining and useful – but you have to work hard. The course is very challenging…but rewarding when you get it right! 3 Your task: Snapping Shoelaces Skills tested: Recall Data manipulation Common sense Designing a practical Physics: Young’s Modulus Materials Elasticity Brief: A sweet manufacturer has to be certain that its popular ‘Strawberry Shoelaces’ will snap if put under enough tension. This is to avoid any accidents should the product becoming wrapped around small children’s necks. How would you calculate the breaking stress for the product to test this requirement? Plan an experiment to find this value. You are going to complete a task in pairs. How you approach and think through the task is as important as the final outcome! Extra information: 1. The stress, σ, applied to a material can be calculated by: Stress (σ) = force applied (F) ÷ cross sectional area (A) Where stress is measured in N/ m2, force in N and area in m2. 2. The breaking stress of a material is the stress under which the material will yield (break). 3. Weight (N) = mass (kg) x gravitational field strength (N/kg). Take gravitational field strength as 10 N/kg. 4. Diameter of the laces = 2.44mm = 0.00244m 4 Plan What equipment will you use? What is your method? Breaking stress of the Strawberry Shoelaces: ..........................................N/m 2 5 Developing Problem Solving Skills Students taking Physics to advanced level (AS and A2) must develop problem solving skills to enable them to explore a problem and identify different ways of tackling it including investigation and mathematical manipulation. You will need to: • Identify, analyse and accurately describe the problem. • Show that you know and understand what must be done to successfully solve the problem. • Select appropriate methods to solve the problem, then explain - giving reasons - the choice of method(s) used. • Show that you have considered the main risks involved. Equipment List In order to be successful in Physics, you will need to be organised and prepared for each lesson. You need to come to each lesson with the following equipment (as a minimum!): • • • • • • • Pen, pencil & rubber Lined paper Scientific calculator (that you know how to use!!) 30cm ruler Protractor Compass Set square To keep your notes tidy, get yourself a few folders with dividers and some index cards for making revision cards. You will be provided with a text book to accompany the course, which should be brought to every lesson. The VLE will also be used as a source of information (uploaded notes / past papers / discussion board). 6 Summer Preparation To prepare you for AS Physics, we have a number of tasks that you must complete over the summer: Task Done Go through revision book (you need to purchase this from us)* ISBN 9781847621153 Head Start to AS Physics, CGP Learn SI units and quantities (beginning of the book). Learn unit prefixes (beginning of the book). Learn Sections One and Two for the first Physics unit. Sections Three and Four will help you with the 2nd year 12 unit, so read through these topics (these topics will not be in your test in the first week). Maths Skills Self-Assessment checklist (see next page). If you are unsure of a concept, use GCSE revision websites and your own KS4 notes to recap it. Prepare yourself with the required equipment, plus folders and dividers to organise your work. *You will be tested on this in the first week back, as we believe that this preparation is essential! You will also be tested at the beginning of October to make sure that you are making the necessary progress on the course. A bit of extra work before you start will really help you get going with the course, so invest some time in building a really good foundation for yourself. Please bring this booklet in, showing the completed tasks, at the beginning of Y12. Enjoy your summer, and we look forward to welcoming you to Team Physics in September. 7 Maths Skills Self-Assessment Checklist Graphs Plot a graph using two variables from experimental or other data, using appropriate scales for graph plotting.
