I was wondering what are some of the labs that you have completed to turn in as your Biology IA's? Can you also explain some of what the experiment is? It is getting pretty close to deadline time and so far my class has only completed one Biology IA and that was done last year with our old teacher. Our new one has not even discussed IA's in detail. Sometimes she gives suggestions on the little labs we do to turn it into our IA's, but honestly, those labs are really stupid. Some of my classmates were thinking about taking some other IA ideas and do all of our IA's on our own. Any suggestions? Well, the one lab that we completed last year was on measuring the densit…

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?

Hi guys!! I am currently working on my IA for ESS and I need to collect some data. My topic is on how the use of electricity has been affected during these times. I have been trying to collect electricity bills from the month of December as well as the number of people living in the household. I need to collect up to 20 bills for my data. I have been able to collect around 12 bills. I know some of you guys know the struggle I am going through trying to collect this data and I would really appreciate it if you guys are able to fill out the information in my form. Thank you!!! https://forms.gle/8GcBE715vGKwgixw9

Hi everyone! I am currently working on my IA for Environmental Systems and Societies and I made a survey to collect my data. The research question I am researching is : How does a family's income correlate to their carbon footprint? I am focusing on Socal / the Los Angeles area since I live here so if you see this and live in that area I would appreciate it so much if you took my survey. Thank you!! 😊🙏 the survey: https://forms.gle/8WmELXbVKg2QqtH67

I had to switch to a database ia due to corona not allowing me to visit my school lab and i have no clue how to approach it at all- some samples i've seen online only dealt with 10 countries but my teacher says i need 20-30 at least. Originally my independent variable was real GDP growth rate and my dependent variable was CO2 emissions. My teacher said I was at risk of turning it into an geographical/ESS based ia and recommended i look at a certain plant/animal species for my dependent variable instead. I researched all weekend and can't find a suitable dependent variable that has a strong correlation to real GDP growth rate (in 20-30 countries as well holy ****…

Hi guys. For my biology IA topic, I decided to focus on genetics and the subtopic would be inheritance. I have a few ideas on what to focus on but I need to narrow it down. So here are some of my ideas: Investigate on genetic diseases. Find the correlation between the variables that led to a specific genetic disease. Investigate a specific gene that led to a genetic disease. Focus on dominant/recessive alleles and how they affect generations of families I was thinking to choose between with family genes or plant genes. What should I focus on? Hope you guys can help me

Hello everyone, I am currently writing my final draft for my Biology IA but I noticed that there is a roadblock ahead in my progress. From what I have found online the independent variable needs to be quantitative but for my IA my independent variables are using different chemicals and seeing how much E. coli can be killed. May I ask if this is still acceptable? Many thanks for your assistance!

I lose many marks on db questions of bio and paper 2 questions of chem. I usually think that my answers are right and complete but they turn out to either be wrong or incomplete. I also feel like some db questions need external knowledge to be answered which are not provided in that chapter. Can you please give me tips on how to answer bio db questions and paper 2 chem question? Also, am I right about needing to know external information in order to answer db questions?

I recently started on my Biology IA and yesterday finished my experiment. The topic for my IA is what is Best Way to Retain Protein within Vegetables in relation to the Amount Needed for Human. I was going to measure protein by looking for the pH (which I did tons of research on). I used pH strips and sadly I don't think they worked. My question is what should I do? I have numbers I can put into a data chart but they well DEFINITELY be off and not accurate. I know that we have too talk about human error and things that affected our experiment so should I just put that information in that section of my paper? It took me about over 7 hours to the experiment and I had to buy…

Hey guys. I have two IA ideas for ESS and I was hoping someone could help me choose which will be better: 1) What is the demographic breakdown of Environmental Value System preferences/adherents regarding trends in age, gender, and nationality? 2) Why are bees so crucial to our survival, and how long would we survive following their potential extinction? Literally any advice would be appreciated :)

I have had a couple ideas now, but none of them seem to work out and i am running out of time, i guess i could say that i am desperate. My first idea was to look for bacteria in cosmetics, but i needed to choose one bacteria specifically, and i just knew that i would not be able to justify choosing that specific bacteria and justify its relevance, if anyone's got any ideas, i would love to hear them (if i wasn't clear, i don't know how to justify the relevance of looking for a certain bacteria in cosmetics). I was also thinking about testing the effectiveness of foundations with an spf factor, but i can't find a methodology to test it, i thought about using a thermal came…

From May 2016 session, science IA is changed so that students can do online database analysis as their IA right? I want to write something similar to this one --> https://ibpublishing.ibo.org/server2/rest/app/tsm.xql?doc=d_4_biolo_tsm_1408_1_e&part=8&chapter=10 which takes the database from WHO and sees the correlation between the incidence of a disease and HDI (Human development Index). Is there anyone who wrote online database analysis IA this year and scored well (7) ? Since this is a new thing, my teacher is kind of negative about it... But I still want to write it, as I can't think of any original IA experiments. Thank you!

Okay so I'm doing my biology ia as a database. The correlation between lung cancer and pollution for each country. The problem is that the data for air pollution is given for each city in the country. I will attach an example. So if I put everything as Raw data, it would be too much, but if I average out the values for all the cities to represent one country, would it still be considered raw data? I'm doing it for European countries only so please if someone has any tips on this matter. Belgium Data.xlsx

Hi, I'm currently choosing my topic fo my IA and I'm really struggling with it. I'm aiming at 7 as the total score for Bio, so I would love to get the highest grade possible for my IA (possibly a 7). I want it to be simple and possible to do at home during lockdown. My first idea included the influence of pH on lactase, but it seems too simple to me, so I started to look for some other stuff. The topics that I was interested the most were enzymes (perhaps something more difficult and original than lactase) or something connected with yeast. My other idea was to do something connected with mitotic index, but I don't really know if that would score high and if I c…

After marking me and my friends marking it, I got a 22/24 and I dont know whether that is a 6 or a 7! I saw that in 2016 this would be considered a 7 but I could not find any further information!

So should I pay attention to this section or not? I'm a bit paranoid about missing out on stuff I should know since I'm already kinda struggling with HL Bio. Thanks for your input! xx

Hey! So my current topic for my Biology HL IA is "How does pH affect the glucose content in milk?" and I'm not sure if it is good enough to get a good grade (7). I wanted to change the pH of milk by the addition of bases and acids and then adding lactase which would break lactose into glucose and galactose. Then I would use glucose test strips to see what the content of glucose in all of the samples is. Is it good enough? Should I make it more complicated by checking something else? Or should I look for another topic? All tips and help would be much appreciated!

I have just read a thread which specifies NOT to do any group 4 essays without experiments, but, up to today, I have arranged my essay with my supervisor (who has never taught IB) to be literature-based, and I beleive it is too late to change that now; will that affect my grade? Also, I am vegan and was wondering if I take a blood test wether that can be used or identified as an experiment... What do you think?

Hi everyone, I don't have enough time to do a lab, so my teacher is making me do a database IA. There's new research that shows bee venom prevents arthritis, and so I wanted to investigate the relationship between the bee population versus arthritis diagnoses over time. My hypothesis would be that with the declining bee population, there would be higher rates of arthritis. Would this be a good topic?

Hi there! For my Biology IA, I'm thinking about doing a database investigation and investigating the relationship between a country's literacy rate and HIV infection rates. My only worry is that it is not related to the biology syllabus enough to get a good mark? I have seen the tuberculosis and HDI exemplar and that got a good mark but the syllabus relation wasn't always obvious so do you think this would be an ok topic to explore? Thanks in advance

Hey guys, I was assigned my first IA for HL bio today, and it has to be on osmosis. The topic is "What is the effect of variable X on osmosis rate?" however, the teacher said that it doesn't necessarily have to be about osmosis rate. I have some ideas so far, but I'm new to HL bio (well, bio in general, since I was in HL economics before) and I need some help and guidance in regards to good titles and labs for this topic. My ideas so far are: -Osmosis rates on different vegetables (potato, cabbage, idk.) -Osmosis rate for potato slices of different sizes (one with more surface area, etc.) -Osmosis rate on 3 different slices of potatoes (or any other vegetable/etc. that …

Hi there! I'm currently doing pre-IB and it's time for me to choose subjects for DP.

It's not like I'm really bad at it, I just can't imagine taking chem HL :''') I don't know which uni will I choose, I don't want to major in medicine that's for sure. There isn't much information on uni requirements for majors like behavioral biology, primatology, just bio subjects which don't lead to medicine. If you have any advice or s…

Hi! I'm doing my EE on biology secondary research and struggled looking for samples or direct guidance at all so I mainly relied on the IB EE guide book. I've summarized the key points they mentioned for Bio and another summary under the actual text because the other summary I originally made was still too long. (yes. it's that wordy.) so there are two summaries, you could say. Most of what they say are a bit repetitive so I will be posting another clearer version of this once im done with my finals on thursday. If you guys want, I can also change it to a checklist format to make it easier. Hope it helps! BIO EE CRITERIA.docx

Hey, I am currently working on my ESS IA, whereas my teacher has approved my topic, however as my thought was to use (and cite as my main source, but obviously not the only source) a government-controlled experiment report, she was quite clear on the fact that this was not tolerated, as I needed to collect my own data. Yet, I cant seem to find anything from an official IB source stating that this is a requirement. As per my topic is quite complicated, it is practically impossible to gather data myself, however, I have loads of data from that report. So, if there actually is a requirement to gather own data, I have to change my topic. The report is describing why and …
