  1. Okay, thanks for providing a starting point for my research!
  2. 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.
  3. 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
  4. 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!
  5. 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!!
  6. 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.
  7. 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)
  8. 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.
  9. 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.
  10. 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"
  11. Hi everyone, I found an interesting maths IA topic that really interests me but found out that someone is using the same topic for her extended essay. So can I use the same topic for my IA? Thank You!!
  12. Hello procrastinators, Are IB paper questions ever repeated? Now by repeated, I don't mean word-to-word––is it possible that papers can have the same question, but with a different wording? When I was in IGCSE, all my teachers said that questions will never be repeated. But after doing many past-year papers, I realized that questions were repeated, usually not word-to-word. I'm not talking about those small definition questions. Are other questions repeated? Thanks!
  13. Are there any good web sources or notes for the Carol Ann Duffy poems––especially Foreign? I know that I probably shouldn't be asking this here, but my teacher is quite bad at explaining and didn't discuss most of the poems in class, she expects a lot from us. Thank you, any help is appreciated!
  14. Thank you so much for the quick reply!! But my teacher told us NOT to use any texts we did in class; she wanted us to find texts from another source, so I decided to use advertisements.
  15. Hi, Are advertisements (and references to movies/shows) suitable primary data sources for an FOA on cultural and gender stereotyping? Thanks! My FOA is in 2 days!!
