Because I work within hospitals I do ethics applications for my projects. Because I have designed projects, written up their workplan, pitched them to hospital teams and executed the projects, I have learnt a lot about Ethics Applications. Because I supervise PhD students, Masters Students and Honours students - I say to them; "Hey, would you like to learn how to do an ethics application?". "So that you can put it into your CV and go looking for part time research work?"
I focus upon 'project design' aka how to design a project and how to describe the design as a workplan.
For the nitty gritty details of ethics the youtube Playlist I have made does a good job to get your learning to a good place.
