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 am very pleased with the website and the material. Love the animated multiple choice test questions. That is a great way to ask questions and cannot be accomplished with questions on paper. Also, the labs are very good and the suggestions are very...

InThinking Physics is a valuable resource. If you are teaching IB Physics for the first time, then it is an absolute must-have. The materials provided are practical, easy to follow and full of interesting resources.

Golf trick real or fake?

I saw this golf trick on instagram and was immediately suspicious, 40 years of teaching physics does that to you. The ball just doesn't seem... more

Here's an interesting one. I got this compressor for painting my car, as it happens I'm not going to use it. All the mixing... more

    While processing results do the students have to find the standard deviation / I do not find this explicitly mentioned in the syllabus.

    Some of my students use Mac, they are not able to load Loggerpro on it, is there any alternative ?

    Yes interactive physics is expensive, use Algodoo instead.

    Is Interactive Physics a paid there any other alternative which students can install in their laptops

    cable resistance
    Because of the increased voltage drop in your cables the compressor motor does not receive the full 230V with a consequent reduction in back emf. The difference between the forward and back emf’s has now increased and more current is drawn...

    All my students have a copy of lp on their laptops. This is allowed by the license agreement. I have 4 pasco benches but no dark room.

    Loggerpro is procured by the school and installed in one laptop used in lab. How do all your students have access to Loggerpro ? Do you have dark room , with optical bench ? What other equipment are must have for lab ?

    Most do their IA on mechanics which is completed in term 1. By doing it early the students have no other commitments so can really focus on physics for a while. Students still remember how to use logger pro etc. if you leave it until after...

    If the students have to complete IA by May they would have started thinking about the topic sometime in January. By then we would be half way through SL syllabus. While students who take HL have to do IA in a topic suiting that level. How...

    I have collected IAs already at the end of May. They are not externally marked but a sample are moderated.
