  1. Hi, I've just started my Computer Science IA and I'm having a bit of trouble on deciding what to do for my IA. I just wanted to know if anyone had any ideas for an IA topic and whether anyone had any exemplar IAs that they could send me. Thanks in advance!
  2. 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?
  3. 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!
  4. Hi, I'm having trouble calculating the uncertainties in an average value. I have obtained several values for VIt (Voltage x Current x Time) and wish to average the values. How do I calculate the uncertainty in the average value of VIt? The issue I'm having is that each value of VIt has a different uncertainty. How do you calculate the uncertainty in the average value if each value has a different uncertainty? Thanks, abarnes98
  5. Hi all, I am currently writing a Design Lab for a Physics Lab Report. The aim of the task is to dip a resistor in a calorimeter filled with Deionized Water and measure the heat energy by the temperature rise in the water. The issue I am facing is whether I can actually obtain Deionized Water. Is it possible to make Deionized water in a school lab? If not, are there any alternative methods anyone could suggest to measure the heat energy of a resistor? Are there any alternatives to water, that I could use in the calorimeter? I need this information before Sunday!!!! Thanks in advance!
  6. Well for the past two terms, all my class has done is review vocab from each topic. We've done one test so far, a full length practice paper 1 over the course of two lessons. We've done pretty much the same thing as you in class, so I am guessing you are on the right track. I think for the final exams all we really need to know is the vocab for each topic and the tenses (Have you looked at the plus-que-parfait yet?) as well as grammar. I'd recommend looking at the topics in the syllabus and developing and reviewing your vocab for each one outside school.
  7. Just a simple guide that might help with Physics IAs.
