Your Investigation work will be done primarily in your Investigation Workbook – a hard covered, sturdy, A4-sized sketchbook that you will make your own. It is absolutely essential that you acquire such a sketchbook within the first week of school. You will need to complete 5 or more pages per week. Your investigation work will be developed and evaluated according to several key criteria. Some of them overlap and involve other criteria, and should be considered parts of a holistic approach to your book.
