    Physics EE

    For my physics EE I decided to look at gravity and stability(my topic) and "how does the loading of a truck affects the shift of the central gravity and how that shift affects the tipping point of a truck if its in a stationary position?"(research question) . For my experiment I've used blocks of different masses that I placed on a aluminium platform using different variation. Where aluminium platform is like a truck platform and the blocks that I used act like loading. So basically I placed them in different ways and looked at the which angle each object will tip over. In my essay I will show how does the central gravity shifts and how it actually affects the tipping point. Furthermore, I want to convert the masses that I used into real life masses, to show that if the mass goes over the limit mass then its becomes dangerous. I am also connecting it to many real-life situations from Africa, where many trucks are overloaded and very often they tip over on the road. I will also explain how can suspension and speed decrease or increase the tipping point. Could someone give me any ides how I could improve my ideas or even my topic or research question, so my essay is not that broad. Thanks
  2. Hello, I am starting my IB program this year and I was wondering, in order to take Language B (either SL or HL) do I have to know this language beforehand? I will be attending school in Sweden, however, I am not from there nor have I spent more than a month there. I am planning on taking Spanish HL (I have been studying Spanish for four years) and I really want to learn Swedish. So is it possible to learn a language without having an experience in target language? Thanks in advance!💘
  3. Writing my math IA and I want to do something with earthquakes, but I have no idea where to start. I’ve been thinking about maybe doing epicenters or the Richter scale but I can’t find a solid way to incorporate them. If anyone has any ideas please reply!
  4. Hello Can anyone tell me how big the gap between chem HL&SL and econ HL&SL are? I'm currently taking math, chem, physics HL & english langlit, mandarin B, econ SL. Would dropping chem from HL to SL and switching econ SL to HL reduce the workload? I already feel quite overwhelmed by the amount of work from math&physics HL
  5. Hello, I have been an IB Physics teacher for several years and I started creating videos for my students and for my Physics website (PaperPlainz.com). I started uploading some of them on Youtube and I just wanted to let you know that you can watch them here. I am continually working on videos, practice questions and other IB Physics materials, so keep checking for new resources from time to time. Have a nice day, Peter
  6. I need help... I don't know if I should choose Chemistry HL, I was a Core IGCSE student and I'm not very good at chemistry or an overall intelligent student , I was in the top 5 but as a class we are not very good anyway.Should i choose it i have until the 3rd of November to choose my options. Ohhhh. I'm also a hardcore procrastinator and never really do things on time. Is CHEM HL really hard? or if i study will i be able to do it
  7. Hi, I'm sort of having a dilemma with my courses for next year. I'm currently in pre-IB (grade 10) and am entering IB next year. We already picked our courses, but there will be a day where changes to our courses can be changed. So currently, my courses for the next two years are: HL English (Lang/Lit) HL Biology HL History SL Chem SL Math SL French But, the thing is, I'm debating on switching HL History to HL Business. I'm going into sciences, so neither will really help me. I pretty much have no interest in either business or history either, but they're the only HL humanities that my school offers. Now, HL History is a hell lot of work. That I know. But the History program at my school is really good, and the class average coming out of exams is usually a 6-7 (97% avg). But I have no interest in history, as it bored me to death this year, and I really have no time or patience for the amount of work that HL history is perceived to have (essays every other week..? No thanks) But I do think that it might be worth it for the 7. HL Business is a different story. It has less work, and I'm slightly (very, very slightly) more interested in business than history. But, the business program at my school is horrible--since the course is new. It's disorganized and the marking system is messed up. The average coming out is usually really low. Really, I just need a placeholder since I have one HL left. And I have no clue which one I should chose because they both have their pros and cons. I know I won't be happy in either, but I have no choice. So which do you think is the better choice? Which option would I benefit most from? Which has less work? Which one did you enjoy more? Thanks!

    This is my written task two from May 2019 exam session. The question is: How and why is a social group represented in a particular way? My teacher gave me a 6 on it and I got a 6 in HL Lit Lang from IB. I hope this can help some people.
  9. I want to investigate the use of math in GPS. however, I feel like its too broad of a topic how can I make it more specific?
  10. Hi, I am in my first year of IB and I have 4 HL's. I am debating on dropping either Geography HL or Economics HL but don't know which one to drop. Which one should I drop?
  11. I am halfway through my summer holiday and I have not started writing my EE because 1. I'm very confused as to how to write it in the first place 2. I don't know where to start. My supervisor left my current school and did not really give me useful advice or insight while he was there, he did not even read the semi-draft that I gave him so I still don't know if what I've done is on track or not! I've read a lot of tips on how to write history EEs but most of them contradict each other so now I'm so confused as to how I should structure or approach my question. Any advice or guide will help
  12. I'm planning to do Economics at the UK for uni and was wondering which HL would be better for me, psych or history HL? My other subjects: HL - Math, Economics SL - Biology, Eng Lang Lit, French ab initio Thanks in advance!
  13. Psychology IA Statistics Help (Tversky and Kahneman 1974) I chose to do my IA on the Tversky and Kahneman 1974 experiment on the anchoring bias. Basically, it was an independent samples design. In condition A, the participants were asked to estimate a numerical expression in ascending order 1 X 2 x 3 x 4 x 5 x 6 x 7 x 8. In condition B, it was presented in descending order 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1. I already ran the experiment, but my problem is with getting the statistics. As it is independent measures, my teacher said to use the Mann-Whitney test. However, when I input my data, I get this notification: The sum of ranks for samples A and B combined does not equal [n(n+1)]/2. Please check your data entries. Do you have any suggestions for what to do? What test to use instead?? Or do I stick with the test and create ranges (that's what my teacher suggested)? Any help is appreciated. If you want to see the original experiment https://msu.edu/~ema/803/Ch11-JDM/2/TverskyKahneman73.pdf (Study 6: Extrapolation) *Btw the actual value was 40,320
  14. Hello everyone, I need help to chose a question for my HL History IA. I was thinking about doing the battle of la Drang for the topic. It would go something like to what extent was the battle of la Drang a victory for US forces? Is this a good question? If you have ideas on how to improve the question I'm all ears Thank you for your help
  15. Hi guys, I need some second opinions on my Biology HL IA, I'm doing an experiment on the effect of different carbon dioxide concentrations on the hormone ethylene's ability to ripen unripe pears. It's basically a spin-off of the simple "put-an-unripe-fruit-next-to-a-ripe-banana" experiment in which the ethylene hormone that is released by the ripe bananas helped accelerate the ripening of the fruit next to it, with the added twist of examining the effects of different carbon dioxide concentrations on this phenomenon. The ripeness of the pears would be measured using glucose extraction. 1) The lab at school has a CO2 sensor that I can use, but I'm a little loss in terms of trapping the carbon dioxide into an airtight container with the fruits for days. My source for CO2 is dried ice. Should I put the dried ice inside the container with the sensor, then wait until it reaches the concentration I need before taking the ice out and quickly placing my fruits inside? 2) Also, does anyone have a good, clear procedure on extracting glucose concentration from fruits? I found a couple, but some of the steps don't seem to work out for me in reality. They tell me weigh out approximately 1 gram of the fruit sample and then submerge it in 6 ml of distilled water. When I try to mash it up, the fruit sample is just too small. Is there something I'm doing wrong? Or is there a better procedure out there? All in all, do you think this is an appropriate Bio HL IA topic or should I reconsider? I have several other options, but this is the one that was approved. My teacher's fine but she's not the most helpful. Any advice would be appreciated! - Confused Bio student
  16. Hi, so my friend was doing her IA on a company called Godrej Interio. But she just now found out that she was collecting data from their franchisor, not from the company itself. The 2nd draft is submission in another 2-3 days. Can anyone suggest on how to tackle this even if she could extend the deadline by 3-4 days? That would be really helpful
