abarnes98 Posted June 30, 2015 Report Share Posted June 30, 2015 I recently got the results for my physics IA draft and to my surprise, I got a 9/24. I had been marked down in several areas, for which I thought I would be able to score high marks in. My topic revolves around calculating the conversion factor from joules to calories, but I don't have any research that I could use on this. I am trying to relate this to resistors but I can't seem to find anything. Could someone please recommend some exemplar level 7 lab reports for physics as well as some guides to help me score a higher mark for my final draft? Thanks in advance!

kw0573 Posted June 30, 2015 Report Share Posted June 30, 2015 Because of the new syllabus, the only samplers available are provided for free through IBO.org. High-scoring physics IAs typically have experiments that allow a lot of personal engagement (ie self figuring things out instead of following an existing lab procedure) and provide high-quality data that can be used for detailed analyses. The conversion between joules and calories is a definition that I don't see how you could design an experiment around. If you are talking about the former definition where a calorie is the energy req'd to raise 1 g of water by 1 degree Celcius, then the IA is rather too simplistic. You need some sort of extension (like you said if you are able to find stuff relating this to resistors or something). 2 Reply Link to post Share on other sites More sharing options...

You need some sort of extension (like you said if you are able to find stuff relating this to resistors or something). My IA is based around plotting a graph of VIt against mc deltaT, one is in joules and the other in calories. This allows me to determine the gradient of J/cal which is the conversion factor. I was thinking of doing an experiment on the optimum temperature a resistor operates at, but I have absolutely no clue what to do there. Could you please recommend any ideas with relation to resistors? Edited June 30, 2015 by abarnes98 Reply Link to post Share on other sites More sharing options...

Thanks in advance!what's up broi take hl physics and i got a 22/24 for my ia, and i think that equates to a 7the thing with the new syllabus is that you need to have "personal engagement" which is basically bsi came up with a cool story of how i went on a trip and certain situations in that trip helped me find a new concept to explore in physics and made up stuff like that, but make it believable also another pointer is to think of the person reading your ia as an 8 year old, EXPLAIN everything, for example your project is about throwing a metal ball into solutions of different viscosityintroduce the concept and say stuff like kinetic energy is maximum right before it hits the solution... and further elaborate on that and always link it back to your aim. MAKE IT CLEAR---> more explanation shows how much you engage in the activity (this would probably go in your background information section) cite information regarding your concept use standard deviation for calculating error label all the graphs, tables ---> IMPORTANT draw diagrams, take pictures.... I drew many diagrams, about one or two every page to explain more clearly. for example in my evaluation i drew diagrams on how i could improve the experiment like redrawing my lab setup using paint it doesn't matter if you feel as though your ia is too simplistic, as long as you can explain clearly on what you're are trying to find then you will easily get the points 2 1 Reply Link to post Share on other sites More sharing options...
