Which parts of criteria D and E were you most successful at demonstrating in the assessment?

I understood what the problem and the research questions were before the experiment and found through out a good method to extract salt and Iron for a rock. I selected and chose what materials to use and needed and wrote clear and detailed lists of materials and procedure. In the Criteria E, I recorded table and chart clearly processing a good data to show how much salt and Iron there were in the rock with exact percentages and a good layout.

Which parts could you have improved on?

I think I have to improve on processing data with more details with proof and evidence to state my results clearly. In Criteria D, I think I have to list the procedure down with specific details.
