Week number	Date	Lesson content	Lesson resources and links	Homework
2	6 Jan	Introduction - safety, classroom procedures. Units to be studied this term and probable assessment dates. Introduction to forces: what are forces ? How do we measure them? Correctly writing units. Calibration.	Lesson notes	Fill in this form
3	13 Jan	Measuring friction. Static and dynamic friction. Drawing force arrows. Air resistance.	Lesson notes part 1 part 2	Complete the force arrows on the bat
4	20 Jan	Resultant forces. Newton's 2nd Law. Unchanging motion and steady speed or velocity. Units for velocity and their conversion.	Lesson notes	What is the speed of the unofficial world record marathon time: 2 hours for 42.1 km ? Find it in m/s and km/h.
5	27 Jan	The tortoise and the hare  -  'speed' Distance-time graphs Velocity time graphs Terminal velocity - balanced forces and velocity	Video of parachute jump Skydiving forces sheet Lesson notes	When you are watching winter sports on tv, focus on the forces and speeds - how are they changed ? Are they big or small ? How are they improved ? No written work needed - just think!
6	3 Feb	No lesson - TET week
7	10 Feb	How does the force which starts a movement change how far an object travels ? Using googlesheets to process experiemental data - averaging and graphs.		Use your google sheet graph, copy into Paint, add a line of best fit. Email to me : karin.parker@eduouka.fi
8	17 Feb	Planning the paper helicopters investigation	Report headings for the investigation Rubric sheet for the investigation Writing frame Writing frame on google docs - click and then open with google docs. Save with a different name.	Complete the purpose, apparatus and plan/method sections
9	24 Feb	Helicopters investigation
11	9 Mar	Helicopters investigation
12	16 Mar	Home learning work	Weight, mass and gravity: paino, massa ja painovoima After this lesson you should be able to: explain the difference between mass and weight give the correct units for mass and weight identify where a body can feel weightless and why this happens Lesson activity: Start  with this tutorial video These are the videos which you are asked to watch during the tutorial:  'Free fall': - an old one but a good one How to wash your hands in space  - Chris Hadfield has done some fantastic little video clips from the International Space Station V-sauce: what if we were born in space ?	When you have watched these videos, do this task to check your learning.
13	23 Mar	Home learning work	Balance and centre of gravity After this lesson you should be able to: .explain what is meant by the term centre of gravity be able to find the centre of gravity of an object Lesson activity: Start  with this The broom challenge. Karin's lesson video  These are the clips which you are asked to watch during the tutorial:  A fun video on how centre of mass helps with moving The world famous Fosbury Flop A map of Finland outline	Here is your homework. The deadline is just before the lesson next week. This task is due before 8.00 April 1st
14	30 Mar	Home learning work	Let's start with a try out of Microsoft teams at 8.15; if you are used to starting at 9.00 then just join in when you can. I have added you all to Teams and if you are able to, please attend. I want to review the work and how things are going so far. In the Teams meeting, I hope to go through some of the questions so far. Here's a link to an interesting page about how the centre of gravity changes when we move.	There is no homework for this week - well, except for 'at some point in your life, visit Kestilä and see the monument that says it is the centre point of Finland'. There may also be one at Piippola.
15	6 April	Home learning work	Acceleration After this lesson you should be able to: understand the unit for acceleration do simple calculations using the formula F = (change in velocity)/(time taken) Lesson activity: Lesson video to explain the content. Remember you can ask questions in Teams	Lesson task which should be completed for homework. Use your notebook for working out etc.
16	13 April	Home learning work	Let's start with a Teams call at 8.15. In week 17 you will have a test. Sorry. Has to be done. Here is a list of the topics covered and some information. Here is a page of tips for studying for open note tests.  The 'study with a friend' suggestion still works - just do it virtually ! So in the lesson, you can ask questions about the physics you have studied and we can use it as a revision.	The homework will be to study for the test - there is no form to complete and evidence of your attendance of the lesson just comes from the Teams meeting.
17	20 April	Test
18	27 April	Home learning work	Work and energy Tutorial video first then watch these two videos before doing the task. Trust your life to physics Roller coaster physics basic physics	Lesson task which should be completed for homework. Use your notebook for working out etc.
19	4May	Home learning work	Pressure and units Lesson video	Lesson task which should be completed for homework. You can use an online unit convertor to help you.  The deadline is after May 20th.   You have TWO weeks in which to watch this video and do the task - feel free to ask me at any time about the work.
20	11 May	Home learning work	Car crash documentary First watch this documentary (45 minutes, BBC, 2012). If, for whatever reason you think you might find it upsetting (it deals with fatal car crashes) then it is fine for you not to watch it - life is too short to be traumatised by your physics lessons.  The documentary is a bit slow but covers safety developments  and testing really well, and wil lead into the work we will do next week. Task: Traffic laws and road safety in Finland.  Show me evidence you have completed this either in your notebook (as we are back in school next week- yay! , or send it to me in an email. Recommended sources to use (these are in English): Finnish Road Safety Council - Liikenneturva Police Road safety in Finland report (OECD)   alternative link here	Questions: 1. How many fatalities were there on Finnish roads in 2018 ?  (check the OECD report) 2. What things have been done to reduce the number of fatalities on the roads here ? 3. Which group of road users has not seen a decrease in fatalities ? 4. If an off road driver is found to have a breath alcohol level of 0.25 mg/l have they committed an offence ? (Liikeneturva) 5. When are elk collisions most likely to happen (times of day and year) ? 6. A little challenge for you: a mobile police camera flashes at a driver travelling at 62 km/h on Kasarmintie just 200 m from the school.  When the letter from Poliisi arrives, will there be a fine and how much ? (Police  - there should be an online fine calculator!)
