Storytelling is a powerful way to introduce lessons. Nothing captures attention as effectively. For example, tell a five-minute story about your first roller coaster ride, and by the time you get to the topic of potential energy, every student will be strapped in and following along.
The inherent mystery in stories draws students into whatever world you create for them. And it keeps them there as they transform your descriptions into moving pictures in their head.
Stories also provide deeply layered context for students, linking their memories, emotions, and viewpoints to your lesson objectives. This makes complex ideas, like potential energy, easier to understand and remember.
