From PBS Learning Media comes the Shape of Life, a "series of free, short classroom videos that beautifully explore the evolution of the animal kingdom on planet Earth." These short documentary films (approximately fifteen minutes in length) are aimed at middle-school level learners and feature gorgeous images, helpful animations, and commentary from science experts. Shape of Life also features lesson plans, supplemental resources (including additional readings and short videos), and blog posts aimed at science educators. To explore this rich collection, visitors can view the complete library of Shape of Life videos via the Downloads tab, where videos are organized by five categories (Phyla, Behavior, Animation, Scientist, and Other Topics). Here, videos are accompanied by related lesson plans and resources. Visitors may also browse videos and resources by subject tag, or explore resources by Lesson Plans or by Next Generation Science Standards (NGSS).
