This is a great resource for IB Physics teachers. I have been using it and will continue using the same in future. The resources of IA are great. I can strongly recommend to any Physics teacher of the world for this site. Thank you for maintaining the...

The InThinking Physics site has been a life saver. Chris's explanations of syllabus content and assessment criteria have helped enormously with planning and programming. The inclusion of marked IAs in particular was really beneficial when I started teaching...

Kate Baldry, The Friends School, Australia

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...

    Measuring g with a pendulum
    Not really, it’s a bit too straight forward.

    Is this a good idea to do this as an IA for an SL student.

    Hi Avo; Although integration is not a requirement I see no reason to ban it. If a student wants to integrate then go for it. As an alternative they could develop an iterative model. As for uncertainties, I guess the integration will lead to...

    Hi Chris, Is it okay if an HL student integrates the equation of torque in his IA because the torque will be changing throughout the experiment being studied? If yes, then how about carrying uncertainty in the IA? Is it okay if the student...

    They are a mix, some have done no physics before some have done pretty much he whole syllabus. I should add that now my class is student centred the timings are quite different. The times here were lecture hours only.

    Hi Chris! In line with your timing of the topics, I am just curious the background of your students in science. What middle school science had they been exposed to? thank you.
