Quote of the day
We have found a strange footprint on the shores of the unknown. We have devised profound theories, one after another, to account for its origins. At last, we have succeeded in reconstructing the creature that made the footprint. And lo! It is our own.
Sir Arthur Eddington (1882 - 1944)

The InThinking Physics site is designed, written and updated by two physics teachers with physics teachers in mind.We hope that you will find the Getting started section useful if you are new to the IB, physics teaching or these resources. Returning subscribers are also advised to check out this area to make sure that you are using the full functionality of the site.At the heart of the site are the...
The options contain some interesting physics but not all students have the same interest, most schools offer only one option so a student passionate in astrophysics might be disappointed to hear they will have to do engineering. The activities on this website address this problem enabling students to work independently through the option of their choice. They can be used for the students who do not...
The whole course can be delivered through the activities on this website, Chris has been doing it this way for some years. Here is his teaching order.MechanicsActivity: Measurement and uncertaintyIn 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...Activity:...
Whitgift has spent this academic year gearing up for our five-year review. In the Physics department, this means ensuring that our Unit Plans are up-to-date and live. We have several IB teachers so, to reflect our different styles and resources, our documentation is in-house and produced collaboratively. The ‘How To’ guide on Unit Planning contains a template for you to copy and complete.If...
This topic is the first in the Subject Guide, and there are some aspects that will need to be tackled before your students can commence other physical concepts. For students who have not studied physics recently or ever before, they should become familiar with taking measurements, identifying the uncertainties associated with data and learn the techniques for adding vectors. In this section of the website, you will also find a 'Mini Investigation'. This can be an engaging way to introduce students to the IA, perhaps after completing Mechanics.
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...
AimsIntroduce the idea of a research question.Use knowledge of mechanics to develop a hypothesis.Use practical skills to design an experiment to test a hypothesis.Use "detective" skills to evaluate results.Practice writing a formal report.IntroductionIn this activity you will perform an experiment related to a small bow and arrow made from a piece of plastic from an ice cream carton and...
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...
A well planned site with lots of informations in Physics!
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...

Teaching sequencesHi Brad; I finish the whole IA in May of year 1. I find this works well, students are fresh, awake and not bogged down with other deadlines. In preparation I do a mini IA in the first term.
19 Aug Brad Nolen
Teaching sequencesI was curious though - How does the IA fit into your plan? How much of the IA can realistically be completed by the end of DP1?
18 Aug Brad Nolen
Teaching sequencesThanks for describing your sequence Richard. I also have SL/HL combined classes with an additional 30 min HL block that occurs once every 4 classes. So the first few of these blocks may not be used as effectively, but once the students learn...

DopplerCheers Brad. I've been living with Norwegians so long I'm beginning to spell like them. Now it's corrected I'll have to explain the joke, I spelt his name Jeger which in Norwegian is pronounced Yeger. Just my attempt at excusing my poor spelling.

Activity: Electric potentialHi Chris, Do you have anything on drift speed? Thanks, Benson

MCQs: Measurement and UncertaintiesHi Eric; Excel agrees with me that 0.025 should be rounded up to 0.03.
8 Aug eric Jobiliong
MCQs: Measurement and UncertaintiesHi Chris, I think if you rounded to 1 sf must be 0.02%, cause 0.025% should be rounded to the closest even number. is it?

SolutionsHi Fergus; Good point. The resultant force on the ball = N-W but the force on the ground is N so I should add W. I'll change the question to the force on the ball.
4 Aug Fergus Gray
SolutionsHi Chris. In question 2, have you ignored the weight of the ball because it is so small compared to the upward force of the ground? Thanks, Fergus.
