It's free to do and can help breakdown tough topics into manageable chunks. It was rather dull - all I did was watch a spring bobbing up and down - but it was really easy to get good marks because there are loads of things to investigate, lots of calculations to do, loads of graphs to draw, easy-to-find information on uncertainties etc.
Basically, if you're not too bothered about doing anything particularly exciting do that I'm not too sure what you can do to investigate the strength of chocolate - I guess you could test different brands/ types but not much else.
This A-level physics book is designed to follow the OCR GCE Physics A specification.
For the OCR B 'Advancing Physics' specification, see A-level Physics (Advancing Physics).
There are only two from the list that appeal to me, the strength of chocolate and the loudspeakers one, but I am not sure what the variables would be for the loudspeakers experiment. Hi there, While you're waiting for an answer, did you know we have 300,000 study resources that could answer your question in TSR's Learn together section? There is a list of ideas here: I was wondering what other people have done/are doing.
We have everything from Teacher Marked Essays to Mindmaps and Quizzes to help you with your work. If you're stuck on how to get started, try creating some resources. There are only two from the list that appeal to me, the strength of chocolate and the loudspeakers one, but I am not sure what the variables would be for the loudspeakers experiment. I investigated how several factors (surface area, initial displacement, mass, length of spring) affected the time period, damping and amplitude of a mass-spring oscillator.If you find any mistakes, errors, broken links, or if you are able to make the content easier to understand, please do not hesitate to edit and expand on existing content.The new specification contains the following modules. There are 4 exams and 2 practical assessments which are counted as coursework. AS makes up 50% of the course and A2 makes up the other 50%.It may also be referred to Physics 'B' to distinguish it from OCR's other A-Level Physics course. The first three make up the AS Level, and the last three represent the A2 section of the course.All six are required in order to obtain the full A-level qualification.The two books supposedly contain all theory and methods that will be required in the exam whilst the CD-ROM offers a more in depth look at every topic as well other resources such as diagrams for show on an interactive whiteboard.The main method of browsing the text and other data on the CD is via the Folio Views software.Each year, candidates will be assessed on their practical skills.each practical assessment counts towards 10% of the A level and the first assessment counts towards 20% of the AS grade.You can use this book as a revision guide, or as another explanation of concepts that you may not fully understand.Before you begin this course, it is recommended that you understand some of the basic concepts covered in GCSE Science, and have an understanding of the SI unit system (Appendix A).
