Chemistry Extended Essay

Hi all,

I'm a new member, and am planning on doing an extended essay in Chemistry. I am in Lower 6th (Year 12) and am really struggling to find a research question or a title. If anyone knows of any decent topics to write 4000 words on I would be so grateful if you could let me know. I really want to start it early and relieve the pressure of doing it in my final year so any topic would be a great start for me.

Thanks.

I'm doing mine on Liesegang Rings - fairly simple experiment which provides a lot to talk about. I'm year 13, it's due on Monday
