Compare how the same scene is conveyed differently in print versus film, naming specific tools each medium uses.
Books and films tell stories through different tools. A book can share a character's private thoughts directly in words. A film shows a scene through pictures, performances, music, and sound instead, and has to find visual or musical ways to suggest what a book can simply state.
Take the county fair scene, where Wilbur waits nervously to be judged. In the book, White can describe exactly what Wilbur is thinking and feeling. A film adaptation cannot show a pig's thoughts in words the same way, so it typically relies on close-up shots of Wilbur's face, tense music, and the reactions of the crowd and other characters to convey the same feeling.
Mastery looks like: They can compare how the same scene is conveyed differently in print versus film, naming specific tools each medium uses.
Common stumbles: Comparing plot differences only, without noticing the deeper differences in how each medium conveys thoughts and feelings.
