hey thanks for the reply,If you don't know the exact prac they're give you then I suggest you gather all dot points that start with "Perform a first hand investigation..." for that particular module and summarise the method, possible points for validity/reliabilty, risk assessment and relevant theory.
p.s why are you still on the first module?
alright thanks!have a look at the skills dotpoints too, since you'll be getting assessed on some portion of those!
