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...

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...

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...

That's my school in the photo. Plenty of snow but it's melting fast. Pity because it would be great to do a gp4 project in the snow. Some years... more

    Could be interesting if they compare with, for example an iterative model. Might also be interesting to attempt to limit the heat loss so that heat is only lost by one of the processes (convection, conduction and radiation) and see how it affects...

    Hello Chris, One of my students is detecting the rate of cooling of a cup of milk vs the method of cooling. Do you think it will make a good IA? Kindly advice as I ma quite new to IA.

    Hi Colin; That's what I thought but it turns out they're OK with it. Damp squib it is then.

    I think School Management would have a problem with it because it looks like payment rather than prize. Would a token, that can still be spent, be equally motivating but less controversial (even though it is essentially the same thing)

    Word is OK but if you use comments in the margin the space for text gets shrunk, call outs are better. Either way make sure they are still there when you convert to pdf.

    Student's IA's are marked by their teacher with comments and sent to the IBO. Is there a standard format for that ? Can it be done in word ?

    Appreciate your guidance .

    Yes Algodoo would do it nicely but you will have to construct a platform that vibrates with SHM, this can be done by using a bar connected to a rotating disc. Or maybe simpler to use undamped springs. Just tried it, works great with springs.

    Chris will it be possible to do the simulation of this in Algodoo?
  • Could be, I use version 5. Fun though, isn't it. Nice "worksheet for dummies".
  • Got it! It's simply from A to B. Revised the instructions for dummies (who have never used geogebra before) I couldn't figure the end of how to add those values onto the charges. I think there could be a version difference ?
  • It's the same as adding a line but you add a vector instead.
