Quote of the day
I ask you to look both ways. For the road to a knowledge of the stars leads through the atom; and important knowledge of the atom has been reached through the stars.
Sir Arthur Eddington (1882 - 1944)

A couple of days ago I posted about this years group 4 project at UWCRCN. Students are going to measure electrical energy usage over a 24 hour period. The group that gets closest to the actual values will win a prize. In our school prizes are token, icecream or fruit, not very motivating. How about a cash prize? Say 100 Euros, that would be motivating but is it ethical?A real prize is more motivating.Real...
- Introduce the concept of fields to explain how bodies can experience a force without contact.
- State Newton's Universal law and apply it to calculate the force acting on a body close to the earth.
- See how Newton's law gives the correct value for the acceleration of gravity close to the earth and the period of the earth's orbit around the Sun.
- Understand the concept of "field strength" as a measure of the size of a field and calculate field strengths.
- Understand how field lines can be used to give a visual representation of the field.
- Know that field strength is a vector, add field strengths as vectors.
Analysis of data is basically what we used to call data collection processing and presentation plus a bit of the evaluation. As with the other criteria this is a holistic assessment based on the whole report so you can't pin it down as easily as you could with DCP. There are many ways of analyzing data, linearizing and drawing straight lines, curve plotting and statistical analysis, all count...
Practical skills are 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 and is assessed...
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...
This site is well organized and thorough. It gives great insight into the content and how connections can be made for students. I have been using it to help me prepare for the 2016 assessment, and have used resources for each content area and laboratories...

Ideas for investigationsCould be interesting if they compare with, for example an iterative model. Might also be interesting to attempt to limit the heat loss so that heat is only lost by one of the processes (convection, conduction and radiation) and see how it affects...

Ideas for investigationsHello Chris, One of my students is detecting the rate of cooling of a cup of milk vs the method of cooling. Do you think it will make a good IA? Kindly advice as I ma quite new to IA.

MoneyHi Colin; That's what I thought but it turns out they're OK with it. Damp squib it is then.

MoneyI think School Management would have a problem with it because it looks like payment rather than prize. Would a token, that can still be spent, be equally motivating but less controversial (even though it is essentially the same thing)

Beginners guideWord is OK but if you use comments in the margin the space for text gets shrunk, call outs are better. Either way make sure they are still there when you convert to pdf.
15 Feb Sujatha Ashok
Beginners guideStudent's IA's are marked by their teacher with comments and sent to the IBO. Is there a standard format for that ? Can it be done in word ?

Ideas for investigationsAppreciate your guidance .

Ideas for investigationsYes Algodoo would do it nicely but you will have to construct a platform that vibrates with SHM, this can be done by using a bar connected to a rotating disc. Or maybe simpler to use undamped springs. Just tried it, works great with springs.

Ideas for investigationsChris will it be possible to do the simulation of this in Algodoo?

Optional Practical: Electric fields simulation (GeoGebra)Could be, I use version 5. Fun though, isn't it. Nice "worksheet for dummies".

Optional Practical: Electric fields simulation (GeoGebra)Got it! It's simply from A to B. Revised the instructions for dummies (who have never used geogebra before) I couldn't figure the end of how to add those values onto the charges. I think there could be a version difference ?

Optional Practical: Electric fields simulation (GeoGebra)It's the same as adding a line but you add a vector instead.
