Week number	Starting date	Lesson content	Lesson resources and links	Homework
2	7.1	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	Sheet: 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	Read the sheet from the lesson and complete this form
3	13.1	No lesson
4	20.1	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 Lesson notes Worksheet from the lesson Airplanes hit by lightning  How lightning works	omplete 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
5	27.1	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	Watch this video as preparation for next lesson. There is no written task with this homework.
6	3.2	Introducing voltage and current Basics of circuits. Ohm's law and its applications Series circuits	PPT    .  '* Circuit simulation  Click the download arrow on the left (under the title) ans then open the download   Lesson notes
7	9.2	Series circuits	Megasheet of series questions Megasheet of series circuits answers Solutions video for Series Megasheet Parallel circuit megasheet  Lesson notes	go through your notes to check you understand the work so far
8	17.2	Parallel circuits	Parallel circuit megasheet   amended version Solutions sheet for the Megasheet Solutions for Parallel Megasheet video amended version Lesson notes	Complete the parallel circuit sheet.
9	24.2	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 Lesson notes
11	10.3	Battery investigation	Instruction sheet   Help sheet for writing the report Writing frame (pdf) Writing frame as google doc - please save a copy or download it - do not edit the original file. ChatGPT's attempts!	Complete the purpose, apparatus and plan sections
12	17.3	Continuing the battery investigation
13	24.3	Continuing the battery investigation		Work on investigation report
14	31.3	Final lesson on the battery investigation		Complete the battery investigation report - it must arrive in my hand/inbox at the START of next week's lesson
15	7.4	The motor effect	The link between electricity and magnetism The motor effect The generator effect Household electricity supplies - alternating current PPT link   Relay switch Simplish (and decent quality) video explaining what is inside a simple DC motor If you want more info (than you need!) on motors and generators, I recommend the BBC Bitesize site starting here You'll learn all about working out directions of movement and current in high school so do not worry if you do not get this! you do NOT need details of the construction of motors for the test Lesson notes	Study for the test - open notebook. You should know the routine by now
16	14.4	TEST
17	21.4	No lesson
18	28.4	Generators	Lesson notes  This was a short lesson and we spoke about the power outage in Spain & Portugal, and how the electrical transmission grids might be vulnerable. Electricity generation Static map of Finnish energy grid Live map of electrical distribution map The world at night - image from space Video: How electricity gets to you Video: How to fix clean energy's storage problem
19	5.5	the future of electricity generation for Finland	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
