Quote of the day
If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.
(Neils Bohr, 1885 - 1962)

AimsIntroduce conduction in semi conductors.Understand the operation of a PN junction.Sketch the I - V curve for a PN junction.Draw circuit diagrams for full wave and half wave rectifiers.Deduce output for diode bridges.SemiconductorsA semi conductor is a material that is not such a good conductor as a metal but better than an insulator, this is because it does not contain many free electrons. Silicon...

After finishing mechanics I get my students to do a mini IA investigation. They have to come up with a research question related to a bow and arrow, then with my guidance they complete a full report. Mini investigation activity I then mark it according to the criteria. I think it is essential to do a trial run of the IA, even though we scaffold the skills we shouldn't expect students to be able...
Aims Understand how an alternating current is induced in a rotating coil. Derive an equation for the EMF in a rotating coil. Understand why AC power = IrmsVrms . Explain the operation of a transformer. Solve ideal transformer problems. understand why transformers are used in power transmission. The rotating coil In this section we will be considering a rectangular coil rotating in a uniform magnetic...
I've just realised that Kirchhoff has got two h's so I've been spelling his name wrong for the past 40 years. Sorry about that but I don't intend to replace every mention of him or his family with the correct spelling. So if you read about Kirchoff then it's actually about Kirchhoff.
Aims Apply the knowledge about the force on a moving charge to explain induced EMF in a moving conductor. Derive an equation for the induced EMF in a straight wire moving perpendicular to B field. Use Flemings RHR. State Faraday's law and use it to solve problems Understand how Lenz's law is a consequence of the law of conservation of energy. State Lenz's law and use it to find the direction...
Aims Introduce the concept of spin and energy levels. Accept that the frequency of emitted radiation depends on B field . Accept that the relaxation time depends on material. Understand how a non uniform field enables position of source to be determined. Understand the function of nin uniform field and radio waves in the NMR scanner. Spin When a proton is placed in a strong magnetic field it can...

Introduction In this practical the input and output of a half wave and full wave rectifier will be investigated with a datalogger. Method Depending on the equipment available you can either build the circuit by clipping components together or using a soldering iron. If doing the latter make sure that you get proper instruction on how to use the soldering iron properly. The best way to ensure a good...
When This depends very much on when other deadlines are in your school but it can’t be too early as not enough of the course will have been covered and students with English as an additional language would be at a disadvantage. So the end of the first term is probably the earliest feasible time. Using the 10 hours The problem with all the IB deadlines is that students become overloaded with...
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...
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 pendulumNot really, it’s a bit too straight forward.
7 Dec Chithra PK
Measuring g with a pendulumIs this a good idea to do this as an IA for an SL student.

LogisticsHi 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...

LogisticsHi 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...

IntroductionThey 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.
16 Nov Anthony Del Rosario
IntroductionHi 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.
