I use project q to do mine on, it’s what as recommended by my school. It had like a layout you followed and so you just answered the questions - I’m not sure whether the school had to set it up for us though so I’d ask yours what they usually do because ur right the evaluation parts are where you get most of the marks. In terms of information don’t use only the internet as you’ll lose marks for use of resources, find some books which aren’t textbooks relating to any school syllabus (as again you’ll lose marks for curriculum based stuff) but that relate to your chosen topic.
