OCR GCSE GATEWAY SCIENCE SUITE 2016 Electrical Cables Controlled Assessment Practical Preparation Additional science B B723 / Physics B753 / Further Additional Science B B763 Five experiments for students to prepare for controlled assessment. Suitable as a standalone double lesson or over a longer period with electrical resistance theory. 1 Tensile strength; 2 Resistance and type of metal; 3 Resistance and cross-sectional area; 4 Resistance and temperature; 5 Resistance and length. These experiments have been fully tested and work well with simple equipment from the prep room. I’ve done all the trial and error work for you! (Who’d have thought it takes 1.5-1.7 kg to break 36 swg constantan wire?) All variables covered allowing students to discover relationships with resistance or tensile strength. Experiment 4 enables students to write a meaningful risk assessment in due course. Curriculum

Circus of practical activities and calculation covering all the 16 physics symbols and units needed in Key Stage 3. Distance, area, volume, mass, density, force, pressure, time, speed, weight, moment, energy, current, resistance and voltage. This full lesson including workbooks, PowerPoint and requisition list for equipment. Use as an introduction in year 7 or for revision at any stage.

This is a FREE SAMPLE LESSON to show the quality of my work. Please take it, use it and enjoy it! I've uploaded the entire of the GCSE OCR Physics lessons P1-P6. P1 Energy for the home P2 Living for the future P3 Forces for transport P4 Radiation for life P5 Space for reflection P6 Electricity for gadgets Many of these have some very fun and simple practicals, linked homework sheets including marking PowerPoints and all are animated and have lots of pupil appeal. They contain a lot of my life with as many photos as possible taken of me and my family. The photo on the roller-coast is of me and my wife to be, our wedding photo is in digital images, the ultra sound scan is my eldest draught and the various animals are ours. This lesson is typical of my work but by no means my best! Please take a look at my other resources. Curriculum
