Complete circuits. | Lesson notes Early computer What happens if you do not cool a CPU (2006) CPU catches fire Some introduction pages for superconductors. 1. Livescience 2. US Department of Energy 3. Science alert Presentation links 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | complete the superconductor project; it should be finished by the start of next lesson. | |
| 4 | 24.1 | Modelling a circuit. Electrical current-measurement and unit Electrical potential difference or voltage - measurement and units. | Electrical units you will meet: ohm, joule, watt coulomb, volt, amp Lesson notes both classes How electricity works - 10 minute intro video (capacitor details not needed) Do NOT try these at home - Electroboom fails How does electricity move in a circuit ? | Watch this video as preparation for next lesson. There is no written task with this homework. | |
| 5 | 31.1 | Series and parallel circuits Circuit calculations: Ohm's Law V = I x R Symbols and units Calculations in series and parallel circuits | Lesson notes 1 2 3 4 Problem sheet | Complete the problem sheer for the lesson | |
| 6 | 7.2 | Calculations in series and parallel circuits continued | Lesson notes: 8.15 Video for the last part of the lesson, discussing real life circuits Video going through the last question on the homework sheet 10.15 Solution for qns 1-12 Lesson notes Another Practice calculation sheet Solutions to practice calculations sheet and video as I explain the sheet. Sorry about the maths mistake! Series circuits in real life Parallel circuits in real life Simplified house wiring diagram iphone board | Watch this video as preparation for next lesson. There is no written task with this homework. | |
| 7 | 14.2 | Electrical energy and power. Electricity bills and usage | Lesson notes 8.15 10.15 Paying for electricity sheet Sample electricity bill Sample electricity costs Helen (other providers are available) | Go through all the work we have done so far. You are getting ready for a test...... | |
| 8 | 21.2 | Going through what we have covered so far. | Useful resources to help you study - please note that external resources may mention things we have not studied in class (eg mains or AC) Article: how does static electricity work ? Static charge video All about Electricity online textbook (relevant parts: Basic Concepts of Electricity, except the last section on Conventional Current Flow, and Ohm's law up to and including Resistors) BBC Bitesize Video on Electricity Worksheet on electrical power - it has answers on it but I have not actually checked it myself. You may need the formula Power = Current x Voltage and then remember that Power = energy/time | Study for test - remember this video to help you How electricity works | |
| 9 | 28.2 | Test | No homework | ||
| 11 | 14.3 | Batteries | Lesson notes Breaking bad battery History of batteries video (a bit odd) How batteries work video Battery task: links removed. Big battery technology Lithium availabilty | Next week we will be using spreadsheets to produce graphs. Watch this video to refresh your memory. Failure to plot a simple graph using googlesheets will Unleash The Snark from me. | |
| 12 | 21.3 | How long can a battery last ? Using a datalogger and exporting data to spreadsheets directly Plotting graphs using software | Random data Using the microbits help page This video talks you through the main parts: How to use the Microbits. This was filmed a year or so ago, and there may have been updates to the webpage and app interface since then. | Read through these sheets in preparation for the investigation next lesson . Rubric/Task sheet Using microbits help sheet Assessment criteria including student friendly version Writing frame help sheet | |
| 13 | 28.3 | Fruit battery investigation | Lesson notes 8.15 Sample data for you New link Breaking bad battery All the sheets for the investigation can be found here: Rubric/Task sheet Using microbits help sheet Assessment criteria including student friendly version Writing frame pdf Writing frame to download as doc - save a copy and edit your version Writing frame help sheet | finish the purpose (prediction and hypothesis parts) of you investigation. | |

| 19 | 9.5 | Magnetism. Electromagnetism. Motors | Lesson notes both groups History of magnetism video Permanent magnets video Earth's magnetic field video Oersted's experiment video How electromagnets work video Simple dc motor video | Watch the videos and send me an email (karin DOT parker AT eduouka. DOT fi) telling me a) what have you learned b) which video was best, and why! | |
| 20 | 16.5 | Generators and Dynamos. National power demands | Lesson notes Introductory video on power generation Parts of a fossil fuel or nuclear power station Fingrid power market New electrical storage systems How solar cells work AC or DC ? Differences Edison or Westinghouse ? The history | No homework. Well, except watch the film 'The Current War' at some point - poor Tesla... | |
