Week number	Date	Lesson content	Lesson resources and links	Homework
33	10.8
34	17.8	Introduction to electricity. Charges,fields,attraction, repulsion. Conduction and resistance. Static electricity. Earthing.	Physics guide handout lesson notes If you missed the lesson, this video explains the main content	this link leads you to it !
35	24.8	Conductors and insulators-types of materials. Semi-conductors.Units of conductance.Resistance. Complete circuits.	Karin was absent this lesson but the work was: 1. this video followed by these questions (Target Science textbook) where does static come from ? why is it the electrons move, not the protons ? why does someone's hair stand on end due to static ? what happens if there is too much static ? what is earthing ? give a couple of examples where static has been useful in technology 2. this video  followed by these questions: what is a conductor ?   what is an insulator ? what is a semi- conductor ? what is a resistor ?  how is resistance measured ?

36	31.8	Modelling a circuit. Electrical current-measurement and unit Electrical potential difference or voltage - measurement and units.	Weds 10.15 lesson notes Weds 12.30 lesson notes Lesson videos are also available.  If you missed the lesson: the video from week 35's homework covers the facts but the notes made in the lesson may help your understanding.	Watch this video
37	7.9	Series and parallel circuits Circuit calculations: Ohm's Law V = I x R Symbols and units Calculations in series and parallel circuits	Weds 10.15 lesson notes Weds 12.30 lesson notes If you missed the lesson: work through the lesson notes yourself, trying to solve each circuit. We did not complete them all in class, and will continue them briefly next lesson.	Watch this video
38	14.9	Calculations in series and parallel circuits continued; electrical energy and power	Weds 10.15 lesson notes Weds 12:30 lesson notes Sample electricity costs Helen (other providers are available) If you missed the lesson: work through the lesson notes yourself and there is a video available if needed. Make sure you do the homework sheet on circuits.	Practice question sheet Do the question sheet, and here is the video to help you check the answers
39	21.9	Household electricity supply	Weds 10.15 notes Weds 12.30 notes Sample electricity bill How much does it cost to run a gaming PC ? Pick up spikes State of the electrical distribution system in Finland	This form
40	28.9	Going through what we have covered so far.	Presentation 10.15 group Wednesday 10.15 lesson notes Presentation for 12.30 group	Study for the test; it is open note but remember you need good notes. Here is a link which might help you if you are not sure how to study. Extra circuit problems ! Questions p 1 Questions p. 2  Solutions 1 Solutions 2
41	5.10	Test
42	12.10	How long can a battery last ? Using a datalogger and exporting data to spreadsheets directly Plotting graphs using software	History of batteries video (a bit odd) How batteries work video Experiment: using the microbits to measure voltage. How to carry out the experiment - each pair needs a computer.   Introductory video to using the microbit. Hox ! The installation method for the file has changed and now is easier, using a flash drive. When you have the equipment: 1. Install the files on your computer. You will need a flash drive with the files on. Copy paste the files onto the desktop. First click on the makecode-microbit-setup-win64 file. When this has installed, click on the Voltmeter hex code file which should then open in the microbit app.  2.Open this sheet: microbits info sheet and read it. 3. Connect the microbit to the computer using the micro usb cable and correctly connect the microbit to the circuit. Then send the code to the microbit and you will be ready to begin. NOTE! When the microbit shows 'E' (for error), DISCONNECT it from the computer, reconnect and then restart from R using button A. It will not work properly if you do not do this step. Videos to help with data processing: 1. Export data To get the data from the Microbit app into excel (nope) or googlesheets (yes) - the instructions are very similar 2. Using googlesheets for graphs
43	19.10	Autumn break
44	26.10	Fruit battery investigation	Rubrik sheet   Writing frame - open with google sheets then download This video explains how to use the Microbits. 1. Downlad this file: Microbits hex file 2. Go to www.makecode.microbit.org 3. Import the Microbits hex file (it is in the downloads folder on your machine) 4. Plug in the microbit. Close any window that then opens.  5. Pair the microbit by clicking on the three dots by 'download' on the purple bar, bottom right. Follow instructions to pair. 6. Download the code file to the microbit by clicking download. The microbit should show R 7. If you do not have another text under where it says 'Show console, Simulator' then check with Karin.   8. Read this before connecting up the microbit to your circuit.   Using microbits info sheet To start the microbit, press button A. It should display 'GO' and then a smiley face. If there is an E, it is an error. NOTE! When the microbit shows 'E' (for error), DISCONNECT it from the computer, reconnect and then restart from R using button A. It will not work properly if you do not do this step.	Finish the purpose and plan.
