Physics is, hopefully, simple. Physicists are not.

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 to lose any energy. The guy playing the shot has a huge social media following and it's hard to believe he would fake all his shots but stranger things happen. The 3D nature and difficult camera angle make the shot very difficult to analyse but if I were...
After many years of development this web site now contains rather more practicals then anyone could actually do in the two year course. I thought it might be worth making a page showing the practicals that I intend to use with my classes. I will add to the list as I reorganise more of the site. One thing I am realising is that the new system of IA frees up a whole lot of time that can be used for...
From 2014 practical skills will be assessed in two different ways, the internally assessed (and externally moderated) investigation and the externally assessed question on a list of prescribed practicals on paper 3.The InvestigationThe investigation is a 10 hour, 6 – 12 page scientific paper on some aspect of physics that interests the student (ideally). It counts for 20% of the final grade...
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 of chemicals put me off, too much like chemistry. Anyway it has other uses like blowing dust away, sand blasting and blowing up tyres. My garage is some distance from the house so I have to use two connected extension cables to connect to the mains electricity. Everything...
IntroductionIn this practical the mass and diameter of different balls of Plasticine will be measured in order to verify that the mass of a sphere is proportional to the cube of its diameter. This is a simple experiment but introduces the concepts of uncertainties, data processing and graphing.Measuring diameterTake a piece of Plasticine and roll it into a ball. Try measuring its diameter with a ruler...
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...
Introduction In this practical the pressure of a sample of gas trapped in a syringe will be measured with a pressure sensor. Theory Boyles law states that for a fixed mass of gas at constant temperature the pressure will be inversely proportional to the volume. This can be expressed as: PV = nRT Where n = the number of moles R = molar gas constant (8.31 m2kgs-2K-1mol-1) Method Connect the pressure...
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.

My practical programmeThey don't have to but can do.

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

My practical programmeI use a mac and I use loggerpro. Just need the mac version. email vernier if you need to renew your account.
16 Aug Sujatha Ashok
My practical programmeSome of my students use Mac, they are not able to load Loggerpro on it, is there any alternative ?
15 Aug Chris Hamper
My practical programmeYes interactive physics is expensive, use Algodoo instead.
14 Aug Sujatha Ashok
My practical programmeIs Interactive Physics a paid software......is there any other alternative which students can install in their laptops

cable resistanceBecause 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...

My practical programmeAll 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.
8 Aug Sujatha Ashok
My practical programmeLoggerpro 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 ?

Writing an Extended EssayMost 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...

Writing an Extended EssayIf 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...

Writing an Extended EssayI have collected IAs already at the end of May. They are not externally marked but a sample are moderated.
