Week 20 Grade 8
Let's start with a Teams call at 8.15. Today the lesson will be on traffic safety, and how things have changed.
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!)
Week 19 Grade 8
Let's start with a Teams call at 8.15.
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.
Week 18 Grade 8
Let's start with a Teams call at 8.15.
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.
The deadline is just before the lesson next week - May 6
Work for Week 17 Grade 8 Physics Wednesday April 22nd
TEST - attend the Teams meeting and the link will be given then.
The test is open note book.
If you cannot attend, have problems etc. please contact me.
Work for Week 16 Grade 8 Physics Wednesday April 15th
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.
Work to be done in week 15 - lesson date April 8th
I'll be available on Teams for help.
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.
The deadline is just before the lesson next week (April 15th)

Work to be done in week 14 - lesson date April 1st
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.
If you missed the meeting, have a chat with someone who was in the meeting to find out more. Next week we will cover the work on acceleration again.

This is the page for Karin's Grade 8 group 'B' Physics, spring 2020
Work to be done in week 13 - lesson date March 25:
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:
A fun video on how centre of mass helps with moving
The world famous Fosbury Flop
A map of Finland outline
The world famous Fosbury Flop
A map of Finland outline
Attendance form which must be completed at the end of the day of the timetabled lesson.
Here is your homework. The deadline is just before the lesson next week. This task is due before 8.00 April 1st
--------------------------------------------------------------------------------------------------------------------------
Work to be done in week 12 - lesson date March 18:
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
When you have watched these videos, do this task to check your learning. This task is due before 8.00 March 25th.

Feedback from this lesson:
Thank you all very much for feedback from the lesson. My apologies for the mistake in question 6, not having a correct answer, and also the poor sound quality. I'll try to put this right for next time.
The idea is that I am sat at home waiting for any questions through email, Wilma etc. when you do the lesson at 8.15-9.45. Now it turned out that I used Microsoft Teams to have a chat with one student so that is possible next week we can use Teams to interact and you can ask questions etc.. I've also realised you can comment on the Youtube video to provide pretty instant feedback. Excellent!
Remember, this is your education so you have a right for it to be provided.
Now if you a re interested in gravity and black holes, this video can tell you a lot! It is extension work - not compulsory. But you might be bored!
