The American Society of Landscape Architects has produced a number of beautiful and educational animations collectively called "Designing Our Future: Sustainable Landscapes."
Here's how ASLA describes the raison d'etre for this project:
These animations and their supporting materials are meant to help the public get a sense of both sustainable landscape design and the type of work that landscape architects do. Each animation has a companion guide to sustainability education resources. Designed specifically for students from kindergarten to 12th grade, the resources include curricula, games, activity guides, and videos to help classrooms explore these ideas in greater depth. All these resources are at your disposal when you're discussing the profession in your communities.
Here's one of them:
