Incorporating the Themes and Challenges is essentially linking the content with a concept. You've more than likely already got the knowledge, it's just a matter of you yourself sitting down and arranging each piece of content to a theme and challenge.
What we did in class was assign each of our cases to a particular theme and challenge (could link to multiple).
For your question, I'd say grab a copy of the syllabus (or your own notes) with the content and try and link it a theme or challenge. For example, compliance and non-compliance could link to aggravating and mitigating circumstances. Moral and Ethical could link to variances in penalties for young offenders vs adults.
As long as you can make a link and support it (with LCMR -- Legislation, Cases and Media Reports), you will be fine. All the best
