Cloning/teaching approach
Topics, such this one on the ethics(topic) of modern biology, especially need to draw on a wider range of sources than a printed book may provide. This resource aims to help by using a web tutorial interspersed with external links to news and comment. Rather than leave the students to explore too many interests and distractions, a worksheet with questions, enables the teacher to focus the students on a subset of the material. You may well adapt this to your particular need, for example, if you wanted students to have a discussion(ta)in small groups. You might also consider using a blog, chatroom or other ICT tool to record the questioning(ta) and reasoning(ta) around this topic. A lesson planning proforma (or draft lesson plan) includes a list of objectives that shows the scope of the material.
