CaptainCook Posted November 1, 2013 Report Share Posted November 1, 2013 Hi ,I'm writing IA, in which I try to determine mass percent of CaCO3 in an eggshell but I have a problem with formulating a hypothesis. My teacher suggested that my hypothesis should be that I assume that there's no CaCO3 in the eggshell, however, I thought that my hypothesis should be supported by literature (which says that there's about 95% CaCO3). Do you think that hypothesis that my teacher suggested is appropriate? I calculated that it is approximately 91% if that can be of any help. Thanks!

heyit'salison Posted November 3, 2013 Report Share Posted November 3, 2013 In formulating a hypothesis, it would normally be best if you do include some form of concrete information. In this case, it is best to provide that you should say theres about 95% CaCO3, this would give examiners the impression that you actually have a rough idea on what you are exploring. Remember if you calculate 91% instead of 95%, you need to justify the difference and perhaps provide room for improvement (if it is possible to improve) to achieve your calculated guess Reply Link to post Share on other sites More sharing options...

Thanks!There should be NO hypothesis in an IA write-up.If you read the extended information regarding IA you will see this. Reply Link to post Share on other sites More sharing options...
Madhavi Posted November 27, 2013 Report Share Posted November 27, 2013 You don't need hypotheses in IAs anymore! Reply Link to post Share on other sites More sharing options...
