Duration~3 x 45 minute lessons
Students will explore the features for an exposition and create a persuasive poster for a particular marine species or habitat.
This lesson is part of a unit of work on the text Blueback. It assumes some previous study of the text has already been completed. View the full Unit here.
Students will each require a copy of Student worksheet: Exposition planner and Student resource sheet: Exposition example. Students will revisit Student resource sheet: Exposition example in the Lesson: Debate
Students may require access to the library, internet or reference books to plan and complete their persuasive poster.

- Engage students in a whole class shared reading of Chapter 7. Discuss Costello’s attitude towards the ocean, compared with Abel’s.
- Introduce (revise) and discuss what an exposition is – a persuasive text.
- Provide students with Student resource sheet: Exposition example. Read as a class and discuss the elements of a persuasive text in the context of the example provided (you may wish to use Student worksheet: Exposition planner to assist in breaking down the text):
- an introduction that provides background information on the topic and gives an opinion on the statement.
- three paragraphs that each contain an argument about the topic.
- a rebuttal to acknowledge the other side of the argument.
- a conclusion to summarise the arguments.
- Discuss the language used in creating a persuasive text – connectives, low and high modality word choice – and how text is arranged.
- Students will now conduct some research to create a persuasive poster to save a marine species. You could ask all students to create a ‘Save the Western blue groper’ poster, or you could allow them to choose a species (or marine habitat – seagrass, mangroves, coral reef) that interests them.
- Provide students with a copy of Student worksheet: Exposition planner to plan the text for their poster.
