Which writing task is likely to develop a student's ability to write for a specific audience during a recycling project?

Writing a letter to the school principal describing the benefits of a recycling project specifically targets the skill of writing for a particular audience. In this task, the student must consider the principal's perspective, interests, and the type of information that would be persuasive or informative for them. This involves understanding who the audience is, what their concerns may be, and how to effectively communicate the project's value.

In contrast, the other tasks do not focus on a defined audience or the nuances of communication aimed at persuading or informing someone in a position of authority. A poem may express creative thoughts about recycling but lacks the directed purpose of communication to a specific individual. A journal entry records personal reflections but does not require the writer to adjust their style or content for an intended recipient. A list of materials is functional but does not involve a narrative or persuasion needed to engage an audience. Thus, the letter represents the clearest example of audience awareness in writing, making it the most effective choice for developing this skill.
