Textbooks,

Treat each chapter as a book in itself. Lecturers often jump forward and backward in using most textbooks during the year. So activate as the lesson sessions require.

Subheadings are one way to form questions. Usually the section following the subhead will answer the questions.

eg. What are the characteristics of Arthropods.

Skittering, External skeleton, primarily chitin. Protect & support body. Incapable of growth, Shed repeatedly, growing animal. Stiff.

And yes I noted that lipids protein Calcium carbonate may may contribute to the skeleton. It's something I would come back to add to a mind map.

Since I don't know what class subject is about... I'd wonder if knowing the exact names of the processes of moulting and hardening is relevant. That of course depend on the course itself what it is about. In taxidermy, that wasn't necessary.
