I changed the title to make it a question and explained why I was interested in the topic to help with personal engagement, identified the variables and how they were controlled, described the procedure and explained about the source and the uncertainties associated with the data and added fairly meaningless sentences such as There would appear to be no particular ethical or safety concerns inherent in this investigation and one positive advantage is that the lack of primary experimental work makes this a very green chemistry approach etc. The RQ is unfocused and unclear impossible to understand what the aims are, Project is just a series of measurements or a synthesis, rather than an investigation. I just don't understand how I can use a database that is already focused on investigatingsomething and then use it to investigate something else???? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. If you are interested in medicinal chemistry, you could try synthesising. Quick disclaimer; my Biology IA was a database IA, so the majority of the tips I'll share in this post will specifically relate to writing a successful database IA.
