melodrama_lorde Posted October 13, 2016 Report Share Posted October 13, 2016 (edited) I was considering doing my IA about tea (because I'm obsessed with it heh). One idea that I have is measuring the effect of water temperature on the caffeine content of black tea. Considering I'd have to measure the caffeine content at different temperature intervals, and also take multiple trials, is this far too complex? And is extracting caffeine itself a complex procedure for an SL Chem IA? merci merci merci for any help Also, any other suggestions would be highly appreciated.

lucyh900 Posted September 29, 2018 Report Share Posted September 29, 2018 Hiya, I know this was sent ages ago and you've already done the IA, but did you end up doing this? I'm planning on doing this but with a different type of tea. If so, did it turn out well? Reply Link to post Share on other sites More sharing options...
