I was investigating the effect of varying carbohidrate concentrations on the Co2 production during yeast fermentation. Each flour represented a carbohydrate concentration, but each flour also has a number of other variables I can control (like pH, damaged starch content, etc) which is why my data does not fit my hypothesis. Can I still perform any sort of correlation (or any other) test for the analysis? Can I sitll get a good mark If my results are terrible?

The research question I have chosen for my Extended Essay is "Do common commercial pesticides stunt the germination and growth time of Phaseolus vulgaris (the common bean)?" I am planning on buying 5-10 bean seeds and testing different pesticides on each sample, and then measuring the rate of germination and the time it takes for the bean to grow stalks (having another sample with no pesticides as a control group, of course). Firstly, I want to know if this question is narrow enough. Secondly, is my experimental process too simple for an EE? I think if I talk about the importance of

Hey, I have done my IA on E.coli Bacteria, I have investigated and measured the MIC Zone of E.coli with Eucalyptus Globulus. I confirmed with my teacher and everything was fine, i did it. But now I got to know that, MY marks will be deducted because E.coli requires temperature above 30 degree Celsius, and IB does not allow the temperature to go BOVE 30 DEGREE CELCIUS ? Do you have any advice to suggest?

I need to choose a topic for my EE and I have decided on Biology. However I am not sure about the criteria, is it mandatory to perform an experiment that is related to my research question?

Hi! My school doesn't leave a lot of options for subjects to choose from. I want to study biotechnology in university. The subjects that I have picked so far are: Spanish ab initio SL Psychology HL Biology HL Math SL I have to decide whether to take English HL or Visual Arts HL for my last HL class. The school i'm in isn't in the US so at first I picked English HL, but it seems like it would be hard to have both Biology HL and ENglish HL at the same time. It isn't required to take English HL for us (just recommended). Also, my school doesn't have c

I’m going to study the IB next year and I’m thinking of taking Biomedical Engineering in uni. I love Biology, so I was thinking of choosing it as my Science Subject. However, I’ve been told that I have to choose Maths HL and Physics HL in order to be accepted in an university to study Engineering. Is it true? Can’t I take Maths HL and Biology HL, instead of Physics HL? PS I’m going to study the IB in an international school (because I applied to UWC, don’t know if you have ever heard about it) but I’m in the middle of high school right now, so I have already had 2 years of Physics

So I've decided to do my IA on the effects of temperature on the transpiration rate of plants using potometer. I told my teacher about the topic and he approved of it. BUT the experiment and it's results are actually a part of the syllabus. Will there be any problems or issues with my IA later on?

Hey everyone, I have been researching for a biology ee topic to work on but it's been almost a month and I have nothing doable in hand. My Biology teacher, (who is most likely going to be my advisor) has very little to no experience with extended essay and is advising me to choose another subject. I want to major in Bioengineering and Bio HL is my favorite subject, I also want this to help me with admissions and I aim at mentioning this work in my applications but EVERY SINGLE teacher of mine advises me to change my subject as a group 4 EE is apparently extremely difficult to get an A in

We have begun choosing our IB HL subjects at my school, and so far i have chosen English HL and Art HL. I am torn between Economics HL and Biology HL, does anyone have any suggestions for the "easier" HL? I am only the smallest bit better at economics but I am more interested in Biology. Thanks!!

Hi everyone, I wish you all good luck on your exams. I did my grade11 biology HL exam a week ago and I managed to get a 2. I studied a lot but I still couldn't get a passing grade. A lot of people from our grade have the same problem since the beginning of the year since we are all having problems with our teachers (They are new to the ib and have no idea what they are teaching). I Studied and made my own notes using http://bioknowledgy.weebly.com/ as I really found their presentations helpful and I did most pastpapers from 2008-2013. Because I am doing well on the other 5 subjects I was

For next year I'm taking: Biology HL English B HL Swedish A HL Psycology SL Economics SL Mathematical Studies SL Does anyone know what I could study after finishing IB with this?

Im doing biology HL, however, we are very late in the progress. My teacher is not an ib teacher, yet, teaches us SL first then we will move on to the HL. Do I self study HL alongside the SL so that I can do well in the exams? If so, any recommended resources or study tips. Thank you IB family.

Since it's getting close to examination, I've been looking for ways to reduce the time taken to answer particular questions. So I was wondering, is it ok to use bullet points when answering questions? I ask this particularly for long/short answer questions in the bio paper 1, 2, and 3. Also, can bullet points be used for psychology 8 point questions? Or do they for sure have to be essays?

Hey guys I have a few questions regarding the biology internal assessments, since our teacher is new to the IB, he isn't sure of what's going on either... 1) To my understanding, we have to send in at least two labs, and we can kind of choose which criteria to be assessed on? Does this mean we only have to send that part of the lab report or do we still have to send the whole thing? (i.e. I choose to be evaluated on DCP for this lab, so do I send in the whole lab or just the DCP part?) 2) Is there a lot of difference between assessing bio hl vs. bio sl labs? I'm doing hl and I'm afraid my l

My school has a very limited/stupid selection of IB courses. Basically, we are forced to take AP US History for the first 3/4 of our junior year because the state requires it. Then we have to take History HL in the remaining period until we graduate. We take the full two-year plan for English HL, which we are also forced into. Foreign Language SL (required) and Group 6 SL (also required) are both squeezed into our senior year only. Since two of our HLs are chosen for us, we basically have to choose between Chem HL, Bio HL, or Maths HL, because those are the only other courses our school offers
