Quote of the day
Physics is becoming so unbelievably complex that it is taking longer and longer to train a physicist. It is taking so long, in fact, to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve

I have often tried to simulate the rotation of a Galaxy in Algodoo but always failed, today I succeeded. As you move out from the centre the rotation speed should increase but when you get to the edge it should decrease (without dark matter). This is because as you move away from the centre there is more and more mass to orbit around until you get to the edge. In Algodoo you can't get the particles...
I thought I would share the advice I just sent to my EE supervisees.Hi;Most of you are pretty much at the same stage so I thought I'd give some general advice. Writing an EE in physics is a bit different to other subjects so I might contradict what you have been told in the general sessions but here we go:You can't write an intro until you know what to introduce and you don't know what...
I was at an outside party the other night and someone got out a sort of skateboard thing with a motor. One of the teachers had a go and some interesting physics took place. The motor moved the board forward resulting in an unbalanced torque causing angular acceleration around her centre of mass. She broke her wrist.This is what she should have done.Gravity acts forwards on her centre of mass and her...
Every other year the staff at RCN but on a show for the students, this is an other year so we performed. Always used to do do a live performance where I would do some sort of Mr Beanish performance but now I am too Mr Beanish to perform in this way. Students wouldn't know if I was trying to be funny, in which case they should laugh, or just being normal and they shouldn't. This year I thought...
IntroductionThis section is a compilation of all the "mini tests" that I use throughout the year. The idea is that I start each lesson with a test on what we covered the lesson before. I say that's the idea because it doesn't work quite like that in real life, it takes a bit of organising to print them out etc. In reality I'd say my students do on average one test each week,...
I was new to teaching IB and moved to a brand new school with no other Physics teacher and no resources at all... With the huge help from the InThinking Physics site I was able to put in place a course with no problems at all. It has been like having...
I consider Chris Hamper's InThinking page for IB Physics to be an indispensable resource for the course. Whether you use his textbook or not the IA section alone is worth the subscription cost.
This site is well organized and thorough. It gives great insight into the content and how connections can be made for students. I have been using it to help me prepare for the 2016 assessment, and have used resources for each content area and laboratories...

Writing an Extended EssayAs there may be many independent variables, it might even be a good idea to get two of them, and have results compared between them; sometimes this comes to their mind afterwards and it is a shame they would not do so for lack of data...

Writing an Extended EssayThank you - mathematically modelling is key. Hear you.
7 Jun Chris Hamper
Writing an Extended EssayYes, there is a bit too much going on. Would be best to focus on one research question, any of the ones stated are ok. Choose one that she can model mathematically.

Writing an Extended EssayI am also supervising an EE for the first time; my student - who wants to take up engineering - is really taken up with truss bridge models; testing their load bearing strength or efficiency; my concern is 1) the choice of the independent variable...

Googling IA ideas for IB physicsGreat, thank you. I agree.

Googling IA ideas for IB physicsThey could score OK but maybe not 20+. They'd struggle comparing results to theoretical model if they didn't have one. It's probably non linear so what curve should they plot? Errors will be big so could fit almost anyhting. Not necessarry...

Googling IA ideas for IB physics"A lump of plasticine is thrown at a wall, it sticks for a short time then falls of, if it's thrown harder it sticks for longer. What is the relationship between the time it sticks and the speed it is thrown at? I have no idea. Maybe they are...
