  1. yeh I probably didnt make that clear oops what i meant to ask was what exactly is the 'chemistry materials' like what does it entail to distinguish between so like my RQ that I have in mind is food chemistry so it probably sounds quite bio...however I will be making use of a centrifuge and a spectrophotometer, so I was wondering if its 'chemistry' enough
  2. Ok so I have a problem I am facing Its mostly a problem I have with chemistry and most of my seniors as well But what exactly defines a chem IA Essentially what is considered chemistry content I am being told by my chemistry teacher that In terms of a chemistry IA only the the "chemistry content" will be considered relevant But what defines this chemistry content. I have seen sample essays about eggs and vegetables...but they seem very biology Help is appreciated Thanks!!
  3. Yes we are...however Beetroot memebranes is used to teach diffusion and properties of membranes as u mentioned yourself However you can actually use a "prescribed topic" assuming that you do it another method For example I am planning my IA on enzymes which are mostly very generic I can do it but I wont get my personal engagement points (or at most ill get half) However If i take a creative spin on it I will get the marks for personal engagement So originality does get you points but its not that much...im addition its hard to keep it simple and go beyond the syllabus by great lengths (although its advised...which is why I am doing enzyme inhibitos --although this is in the Hl syllabus-- to my teacher its considered not mainstream and therefore I will get a mark for orginality (although its not much) By prescribed content I presume your teachers mean Practicals you HAVE done in class...so if you havent done the beetroot experiment in class then it is fine but be warned you will probably not be able to get 24/24
  4. hey its a bit late sorry bought that!! But in my school for my EE I am also going to be using microorganisms. according to what my school says, as long as the microorganism is not pathogenic it is fine to use
  5. Seems good However you may want to be careful Here where I live, all the schools do beetroot memebrane as a inclass experiment This means we are NOT allowed to do it as an ia Because its mandatory So you may want to check with your teacher
  6. I am not too sure about Chem IA but from what my biology teacher told me (which I will apply to chem as well) is to have at least 20 valid test results. And if you dont get 20, keep doing more until u get 20. Anomalous data would then be removed from your processed data which you can instead place inside the evaluation (but be sure to mark the anomalous data in raw data table)
  7. Lab Report

    from what i remember, my teacher mentioned as long as you use different methodologies you are able to research the same topic. So if you do have a variation in your method you can?
  8. you probably need to if you are doing an IA on human physiology considering the fact the topic is human physiology related. However I recommend (because group4 IA's are not subject bound from what i know) that you do look at what you are interested in but make sure to keep it within reason of ethics and your school lab. so if its cardiovascular system, the IB does not let you experiment on animals more complicated than a small fish, so you may want to study the cells ex vivo instead. I don't know if this applies to every school, but I am also starting my IA proccess for bio and this is what my teachers have told me
  9. i am interested, although I am only in grade 11 is the skype group running?
  10. well from what I know, you can use non pathogenic microbials, you should check with your schools technician. because for my EE my technician is helping me prepare bacterial cultures but she mentioned 'only non pathogenic bacteria can use'
  11. Ok so as the title implies, I am confused as to exactly what defines a chemistry IA. Recently my Teacher has got me started thinking about EE topics, but because my EE plans are mostly for bio, i decided to reserve the EE Chem ideas for my IA instead. What I am thinking of doing is measuring glutamate concentration in tomatoes after drying, HOWEVER I also know this sounds very biology. I have asked many chem/bio and chem/physics students about the defining lines of chemistry and the most I have gotten is "if you titrate it its chemistry :P" but obviously this is not the case. So I checked on the official chemistry IA website, and I found somebody doing and IA on the denaturing of egg white proteins...and that sounds much much more bio. so I really need some extra clearly defining lines...so things like experimental techniques, content, crossovers because when my teacher was explaining it, he mentioned this 'you will only be marked for chemistry components in the IA' so it further begs the question, what is considered chemistry components (other than equations and molocules)
