Since no one seemed to be offering help in biology, I am. If anyone needs help with any topic in Biology, that is Higher and Standard Level. Including the following options: Cells and Energy (for SL, which is aHL topic) Microbes and Biotechnology Further Human Physiology I'm here to help. I enjoy Biology *bio-freak yes* This doesnt take much of my time and I'm doing it willingly. Before you ask a question about a certain topic, make sure it's not listed below. *TOPIC 2 (2.1.9-10)---*Stem cells and therapeutic use* (Second part of the post-scroll down) *TOPIC 2 (2.4.8) -- *Endocytosis and Exocytosis* *TOPIC 2 (2.5) -- *Cell Division (Interphase and Mitosis)* *TOPIC 2 …
I keep getting the same question, about how to do well in HL Biology, so thought I should just put it out in a topic. Remember that this is what I am predicted, not sure what the real one is. From what I have seen these are the important points. 1) TRY to like it..and find interest in it. It really helps. If you do like Biology then that’s a bonus! 2) NEVER EVER go to a lesson before you are certain you understand the things covered in the previous one. A main factor of doing bad is keeping things to just gather up on you, and before an exam you struggle to unerstand soo many things when you should be doing past papers. Do whatever it takes to understand something, trust …
Okay, so I found a bunch of notes I took when my teachers were giving us IA tips and format..etc. Some of the below I had to copy of the board, so you may find these in the books. So, Biology IAs should follow this general format: DESIGN 1)Research Question 2)Hypothesis/Predictions 3)Variables 4)Apparatus 5)Method/procedure DCP 1)Collected data 2)Data processing 3)Data presentation CE 1)Conclusion 2)Evaluation Design Research question: This should be a clear focused question that says exactly what you are investigating. It shouldn't be too long and it must include the dependent and independent variables. Eg. What is the effect of pH on the activity rate of salivary am…
These are some tips to tackle Biology questions with respect the action verbs. (BTW, this is taken from the Oxford Biology Study Guide pp.178).
Before we start with this, you need to know that there are three types of examination questions;
- Multiple Choice Questions (Paper 1): You choose the answer from four possible choices. Read them all, eliminate any unwanted answers to narrow them down. Always give answers and never leave questions empty. Leave the hard ones till the end and focus on the straightforward ones.
- Structured Questions (Paper 2 + 3): Each question is broken down to sectio…
hello! I am planning on doing an IA on the environmental impact of food delivery in Singapore. Would it be a good and suitable topic? and if anyone has any tips or suggestions on how to get around this, I would appreciate it very much.
Hi I’m supposed to start my Biology IA but I still didn’t choose the topic or form a research question. I want to do something with animal tissue obtained form a safe source (butchers) like muscle tissue, bones or other organs available. I already have an EE topic about the influence of alcohol on the liver but now I can’t find any interesting research that I can conduct on other animal tissue. If u have any ideas I would really appreciate any type of help. 😊
Basically I’ve been procrastinating so I’m wondering if it is possible for me to pass bio HL even if I only cram SL?
I’ve done good on my other HL exams and should have at least 12 points in HL already so I only need to pass biology. Also I think my IA will be a 4.
thanks in advance
A student has identified that lots of food is wasted at lunchtime in the cafeteria. She has also noticed that younger students don’t seem to throw away as much as the older students. She thinks she could link this to her ESS IA
What topic would this fall under in the syllabus?
Suggest a question that could be asked about this scenario? Try to make it focused, relevant and coherent.
Outline a short methodology that would allow her to obtain sufficient and relevant data to enable her to answer the question you have proposed
Can anyone help me with this. This can be very vital to help me develop my research question.
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…
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 ****…
I have to do a IA on the germination of seeds. I have my independent variable which is salinity. I am looking at it effect on the time it takes for a seed to germinate. I have a few questions,
What is a good range of concentrations? How much of the concentration should I add? What is the best way to get my concentration? Should I add the concentration to the soil and add the salinity of the soil on top, or change the salinity of the soil to a fixed point? E.g. add 1% to soil or make the soil have 1% salinity.
All help would be great! Thanks!
I need to collect data for my ESS IA.
Anyone related with this class or not can take the survey, please do!
Thank you so much in advance! I really appreciate it!
Result will stay anonymous. Also any tips on anything is appreciated as well.
Hi everybody! I need a topic for my ESS IA. But since I’m in quarantine, I need one that doesn’t involve an experiment. Also it has to be easy cause I don’t have much time. Any ideas??
and if possible can you give me 2 ideas?
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…
Its High time I start with my ESS IA and I have still not finalized my IA topic.
First It was how does concentration of different pollutants in water affect the growth of lemna plant?. this was supposed to be my IA but My ESS mentor told that its already there in the OSC guide.
I am interested in soil and aquatic systems. Could you please suggest me some good areas of research!!
An I had one more question
Is more marks awarded to lab experiments than secondary data collection
PLEASE ACKNOWLEDGE SOON
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 selected 2 topics for my IA one is based on primary knowledge and one is based on secondary knowledge. Primary is based on plant growth from water and secondary is based on women equality and deaths caused by natural disasters. Which should I pick?
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.
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.
it is urgent.
I need to submit my biology lab report on next Monday, if someone is willing to correct it by giving me your Gmail account, it would be so helpful.
The lab report is about the yeast respiration (2.8 Cell respiration).
Could you please leave comments on my doc? I will share it with you.
Thanks for your advance!
Hi! I'm beginning to think about my IA and I want to maybe focus on the effect of insulin levels on the respiratory quotient? Is this too simple of an idea? My teacher has left us without guidance on how to pick a question and I'm not sure if this is a viable topic.
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…
I am a junior in the IB programme and my IA rough draft is due next week and I was marking mine and i wanted to know if anybody knows what the boundaries are between a 7 and a 6. 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!
Can anybody help me with this?
does anyone happen to have Biology 4th Edition IBID by Minka Peeters in pdf? The one that is on the ibdocuments is only the "extras" for this book and I really need this book, it's not available in my country, I believe, and due to coronavirus, there are no international parcels coming so I can't really order it
I would be grateful, thanks!!
Hey Guys, so I'm self-studying Option B and I looked at the info on Bioninja - I'm very intimidated by the Extra content (EC) and I see that what is mentioned in this section is not always present in the guide. 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
I just wanted to know if y'all think this would be an acceptable Research question for a biology IA, I'm just doing data analysis from sources. To what extent does a country’s average life expectancy affect the suicide rate within that country? Just a quick yes or no will do, thanks.
I'm looking at different concentrations of nitrate on plant germination and growth, I'm not sure what are the different concentrations of nitrate are there/what i can use, how to obtain these concentrations and which plant seed should i use? Any suggestions on which plant seed would give some interesting results. PLEASE help!!
I did an experiment on the effect of fertilizer on dissolved oxygen levels, and tested it over the span of 5 days. Each day I collected data for 60 seconds, so I have a bunch of data. do I need to calculate the standard deviation, and do a T-test??? that just seems like a lot of un-needed work.
Hi guys. I am sl biology student who procrastinated IA until the day before the deadline, so I really need your help.
My topic is to get the dietary intake of some substance by nations and find the relationship between some diseases that occur by an unbalanced diet.
does this approach seem okay for u guys? I really need ur opinion and advice. Thanks
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 my first draft due in 2 days and my final draft for submission due in 6 days, I have only planned my essay, my essay question is: Are any essential amino acids deficient in a vegan diet? 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? I would also greatly appreciate if anyone knows a place where I can fin…
Hi. I need some advice.
My IA is about fungi so I have some data for growth over time for two conditions of one abiotic factor.
The groups of the fungi in one of my two conditions (they took 2 months to grow bc of various reasons) have no growth of the fruiting body (thus no data).
Thus it seems silly to use a statistical test since I know which condition was the *best ( growth was limited by lack of control of other variables)
Any advice? Will this limit my chances of getting 7? I worked too much on this and now there is no data for 1 condition, just a load of qualitative observations.
Help Greatly Appreciated
