Week number	Starting date	Lesson content	Lesson resources and links	Homework
33	11.8	Magnetism is naturally present in some substances Magnets create areas around them called fields Magnetic objects experience a force in a magnetic field The ends of magnets are called the North and South poles Like poles repel, unlike poles attract The Earth has a magnetic field The Earth’s magnetic field causes the aurora	Terms and Conditions History of magnetism video Permanent magnets video Earth's magnetic field video  Bar magnet and compass simulation lesson PPT Aurora video Lesson notes: Both groups  Fridge magnets - a couple of people asked about the board magnets and why they never repel each other - brilliant question. The answer is that they have alternating N-S pole 'areas' held together on one side. You can feel this when you push them together and they might slide a little as the opposite poles line up. It's called a Halbach array.	This form
34	18.8	Static electricity Electric fields Movement of charges Earthing Conductors and insulators	Charging objects Conductors and insulators Van de Graaff generator Electrical safety Theory and notes about static   Worksheet from the lesson Airplanes hit by lightning  How lightning works Lesson notes Wednesday group Thursday group Benjamin Franklin demonstration in Faraday cage	Complete the sheet from the lesson, and then this optional, possibly life saving extra: read this important information website about the dangers of lightning, and the next time a storm is brewing up, check this  Answer sheet for the homework
35	25.8	Portable electricity - batteries	PPT  History of batteries 7 mins How does a mobile phone battery work - compared to lead acid (3 mins) Task: create a presentation (individual, to be graded just on the slides - NOT on presenting it) which covers: 1. what is a battery? 2. what are the desirable properties of a battery (consider convenience, reliability, safety, environmental and economic considerations) 3. Why is lithium so important in modern batteries? 3. why is battery technology so important in our lives? Use the final slide of your presentation for sources, including any use of AI. Deadline - end of the lesson Lesson notes - Wednesday Thursday	Watch this video as preparation for next lesson. There is no written task with this homework.

37	8.9	Series circuits	Wednesday group: Megasheet of series questions Megasheet of series circuits answers Solutions video for Series Megasheet Lesson notes - Wednesday Thursday group: other work was done (from the textbooks) as I was absent. See me for details if you were absent.	Wednesday group - 30 minutes (maximum) on the series circuit sheet Thursday group: no homework
38	15.9	WEDNESDAY Parallel circuits THURSDAY  Series circuits	WEDNESDAY Parallel circuit megasheet     Parallel circuit solution sheet Solutions for Parallel Megasheet video amended version Lesson notes: Wednesday THURSDAY Megasheet of series questions Megasheet of series circuits answers Solutions video for Series Megasheet Lesson notes Thursday	BOTH GROUPS: Complete the worksheet from the lesson
39	22.9	Parallel circuits  - Thursday group Study for test - Wednesday group	Thursday Parallel circuit megasheet     Parallel circuit solution sheet Solutions for Parallel Megasheet video  Thursday lesson notes Wednesday lesson notes	Go through notes, ready for the test.
40	29.9	Domestic electricity Cost of electricity and monitoring demand	Cost of electricity: Fingrid Energy consumption data for Europe Recent wholesale electricity costs. European energy costs Sample electricity bill Sample electricity costs Helen (other providers are available) Paying for electricity sheet TV pick up 2020 Electricity demand Electricity prices in Europe data Wednesday lesson notes Thursday lesson notes	Go through notes, ready for the test.
41	6.10	Test
42	13.10	Batteries revisited	Solar Night's Sand Battery California Solar panel/battery farm   (stores 3.3 GWh) Gravity storage battery Lesson notes ( only useful for the test points) Work done in lesson: research about the feasability of using fruit/food as a battery in real life	Read your save the planet book
43	20.10	BREAK
44	27.10	Battery inv -research	Investigation task sheet Writing template Graph help sheet Spreadsheet for graph data
45	3.11	Battery inv
46	10.11	Battery inv		Continue work on your investigation. Now you have the data, plot a graph/graphs to show how the current and voltage change with time. There is a help sheet on the blog which reminds you of how to process graphs using googlesheets. Remember to add a line of best fit using Paint, and then copy/paste the graph AND the results (use the snipping tool on the spreadsheet) into your report.
47	17.11	Completing the investigation No lesson Thursday group		Deadlines: Wednesday group - 25/11 20.00 Thursday group: 3/12 20.00
48	24.11		Laptops are needed. Please make sure they are plugged back in to charge after the lesson.  Each pair should produce a powerpoint which is thoroughly researched. It should cover the following: What the current demand for electricity is in Finland.  (Useful: https://www.fingrid.fi/en/)  From what sources this demand is met. (https://www.fingrid.fi/en/) What are the future energy goals for Finland (carbon neutrality etc.) (useful: https://www.treasuryfinland.fi/investor-relations/sustainability-and-finnish-government-bonds/carbon-neutral-finland-2035/, https://ym.fi/en/finland-s-national-climate-change-policy) What are the barriers that may prevent these goals being met. What technological developments need to be made e.g. the future of batteries as long term storage (https://en.wikipedia.org/wiki/Battery_energy_storage_system, https://group.vattenfall.com/sustainability/climate-transition-plan/battery-storage-systems) or thermal or mechanical energy storage systems. Can electricity generation really be carbon neutral? Include sources as links on a final slide.
