  1. Thanks for replying! So finding the surface area and volume was the original idea, but I thought it was too simple for a Higher Level topic. Thanks for helping.
  2. My teacher recently suggested a maths IA topic that I don't think anyone has ever done before. It is about finding the surface area and volume of car roofs, and investigating how the speed of the car is affected by air resistance. I could calculate the surface area using integration, but are there any other concepts that I could possible investigate this? For example, would going into drag coefficient be a good idea? I think it involves some calculus. Thanks for your help!
  3. My RLS involves the exploration of languages. For instance, I realized that in a computer language (programming language), there is one thing that always performs the same task. But in an actual language (the ones we speak in), what you say means something different depending on the context, tone, and emotions. I could also possible connect this to how in scientific development, some language have certain standards, like all animal species' scientific names are the same regardless of the language spoken in. The areas of knowledge I could use are the mathematics, natural sciences, and human sciences. The ways of knowing I could use are language (of course), emotion, and maybe sense perception and emotion. So is this fine for my TOK presentation? Is there possible any way I could shape the RLS better to make it have more TOK aspects? Help is always appreciated! I currently have a few holidays and my TOK teacher doesn't reply to any emails, similar to most teachers in my school!
  4. I wanted to ask whether this topic would be suitable for an extended essay in chemistry. It involves comparing the effectiveness of different (or components in them) of physical and chemical sunscreens. In order to do so, I can either find out the effect they have on the voltage output of a DSSC, or I was thinking of using spectrophotometry. So is this idea okay? The topic is finalized, but just finding the exact research question/aim was difficult. Any help is appreciated as my supervisor doesn't reply to emails and we currently have holidays for a few weeks.
  5. Hi everyone, We were asked to think of math IA topics. I really enjoy doing origami as a hobby. I thought of investigating some topics such as Haga's theorem, or the ratio of an A paper (√2:1) Are these topics too simple or is there scope for investigation? Thanks!
  6. Okay, thanks for providing a starting point for my research!
  7. Hi everyone, I was planning to do my extended essay in chemistry and came up with a topic. I haven't framed the research question yet, but my topic is about UV and sunscreens. So I was thinking about finding 1 or 2 chemicals in 2 different sunscreens and comparing their effect on blocking harmful UV (UVA and UVB). I also plan to determine which substance is more effective at blocking harmful UV rays. Is this topic okay? I wasn't sure whether it completely fits in the extended essay topic category. I've been having lots of trouble finding a good topic. Thanks for your help.
  8. Hi everyone, I found a topic for my chemistry extended essay, but I'm not sure whether it is suitable. It is about conjugate structures in sunscreens and how effective they are from blocking UV-A and UV-B rays from the skin. Is this topic suitable? My teachers said that it is a pretty common topic. Does anyone have any other chemistry extended essay topic? Thank you for your help
  9. Hi everyone, Is Java required in any paper of HL computer science? I am doing databases as the option topic (not OOP), so is Java required? Thanks!
  10. Hi, I had a few questions, and I hope I'm not disturbing you too much! I know a web-framework in Python called Flask and it has its own way of user authentication and database management with sqlite (sqlalchemy). Is it okay if I use these libraries? All database operations can be done with sqlite but sqlalchemy makes the database easier to maintain. Does the look of the website of matter? Should I make it look good or are we not marked on that? Thanks a lot!!
  11. Thank you for your reply! But I will be making a web-based application so it will store data for a number of students, so I will be using a database.
  12. Thanks for giving the useful information! I will be making a web-based application in Python using Flask. But since this topic has been done by a previous student, can I do something similar? (I didn't know that it's already been done)
  13. Hi everyone, We were asked to think of an IA topic in Computer Science, so I came up with an idea but I'm not sure whether it is acceptable. I thought I could make an application that helps IB students manage their CAS portfolio. So basically, there will be a database storing proposal and reflection forms, and students can fill it up and all this data will be stored in a database. Is this topic acceptable? Thank You.
  14. I needed some help in deciding a good topic for a chemistry EE. Till now I've thought of doing it in chromatography and dyes. I thought that the topic of "analysis of hair dyes was overused", so I was thinking of doing something along the lines of: "chromatography of different pen inks", or "analysis of dyes in foods such as ketchup". Thanks.
  15. Hi everyone, Our teacher is asking us to finalize our IA topic and I decided to do something in tourism (in Singapore). So is this topic okay: "How does the number of tourists affect the number of local people in Orchard Road, Singapore?" Is this topic okay? Or too broad? I wanted to do something in tourism, so I was also thinking of a few other topics such as "How does public transport affect the number of tourists in X area"
