I'm in red, he's in black but also yellow.EE Fun FactsEver made your physics teacher blind? I did.I was talking to Chris about the experiment which involves me recording a screeching noise ("eeeeeee") for a period of time and I showed him a quick demo. A few seconds in and chris asks me to stop the sound - HE Cant SEE. The class stood there super confused. Chris left. There are two...
AimsUnderstand that if Newton’s laws are to apply at high speeds momentum must be treated relativistically.Build an iterative model to show how KE changes close to the speed of light.Mexican BoxersAndres and Bruno are two identical twins who share an interest in boxing but so it is possible to tell them apart they wear different coloured hats.Andres and Bruno live at different ends of a relativistic...
AimsState Kirchoff's laws.Understand the connection between Kirchoff's laws and conservation of charge and energy.Solve problems using Kirchoff's laws.Kirchoff's first lawLet's first consider a water pipe splitting in two.If we consider the water to be incompressible write an expression relating the volume into the junction and out of the junction.Now currents in wiresIf charge...
Mirian regularly changes her hair style. In fact she regularly changes her hair, long, short then long again. It's all about braids, apparently. It came as no surprise that Mirian chose to do her EE on a hair related topic.Here’s the fun part, I got my EE topic in the bathroom. I observed that it was easier to get out shower gel from its bottle when I let air in first and this happened when...
AimsTo understand the definition of potentialTo see the connection between work done and area under the F – x graphUnderstand the relationship between line of equipotential and field lines.Sketch lines of equipotentialUnderstand the relationship between V and PEDefine the eVForce distance graphIf a constant force moves a distance d in the direction of the force the work done is F x d. If we...
AimsIntroduce the concept of charge.Observe the electric force.Explain simple electrostatics experiments in terms of moving charge.Introduce Coulombs law.Define electric field strength.Draw field lines for point charges, spheres of charge and parallel plates.Electric chargeWe now use electricity to power many devices but the idea of charge was originally developed to explain static electricity. Take...
AimsApply knowledge of circular motion and gravity to derive an equation for a circular orbit.Derive an equation for the total energy of an orbiting body.Sketch graphs of KE, PE and total E for orbiting bodiesUnderstand why different Earth satellites have orbit radii.Derive an equation for the speed required to escape the gravitational attraction of a massive object.IntroductionHave a look at this...
The IB mark scheme gives the letters of the correct answers but not the complete solution. The examiners report gives some more details and statistics but again no worked solution. Here I have written out how I would solve each problem, this may not be the intended way and there has been a lot of OCC discussion on a couple of them but I've done it anyway. Students need to be familiar with MC...
Here I am going to make a second set of tests for each unit of the course. They will test the knowledge gained in the Activities.These pages will be developed during 2017/2018, my aim is to complete the tests before my students finish the units, however I will probably be a bit faster than that :-)
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...
One of the advantages of the old system of internal assessment was that it was quite easy to produce a checklist for each criteria. This was also one of the aspects that the assessment team didn't like, it became too formulaic. In the new system there are many ways to score maximum marks so its not just a matter of drawing a graph with the correct axes, error bars and best fit lines to score complete...
AimsInvestigate other oscillations.Explore the changing energy in an oscillation.Sketch graphs of KE and PE vs time and position.Introduce phase difference.Is it SHM?Not all oscillatory motion is SHM but if it is you can use the equations for SHM to find the frequency of oscillations. Let's look at some examples.Mass on a spring.When a mass hanging on a spring is displaced it oscillates, you can...
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...
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.
InThinking site for IB physics is a wonderful resource to learn and teach IB physics effectively. I have been trained mostly through Chris Hampers' ideas and innovations on this site. I couldn't have made it without this resource. Thank you for making...

LogisticsCould cause problems if it becomes part of the sample. If pulled up for plagiarism the student will lose their diploma. I'd get them to correct the citations.

LogisticsHi Chris, I have one more question I'm hoping you can help me with. A have just marked a students' report and afterwards, I checked his sources and found that sometimes they do not check out. For example, when I clicked on a citation that looked...

Kirchoff's laws (Geogebra and PhET)Difficult to say, have you got the battery the right way round?
11 Apr Chris Hamper
LogisticsHi Lloyd, Sample data is OK, no appendix necessary. Be wary of checklists.

Kirchoff's laws (Geogebra and PhET)I was trying to find the emf of a cell using a potentiometer arrangement. However I am getting deflection to only one side in the gal. Placing the jockey at the other end does not give any deflection. Kindly help me

LogisticsHi, I have just come across a grading checklist that has all raw data included in the report. Is it necessary to have all raw data included or is a sample table acceptable? A student has a lot of raw data which would destroy his page limit,...

Worked SolutionsYes! This is a great idea!

MarkingAs for difficulty, I think it should be the same.
6 Apr Chris Hamper
MarkingYes I do. I can't use actual past paper questions on the website but could try making something similar. The reason I haven't is because I think it's best to use actual past papers.
6 Apr Sujatha Ashok
MarkingAlso do you use material from past paper 2 to prepare students for data based question. Can you include some questions in this website
