Systems in Motion! Exploring Ups & Downs in the World through an Interdisciplinary Lens creates a space for "kids" from ages five through adulthood to explore and understand how and why systems work the way they do. Each of the seven lessons, with accompanying easy-to-use online simulators, contains multiple curricular connections and also illustrates how perceived problems or undesirable behavior can arise from the very structure of a system itself, as opposed to outside influences. As students interact with the online simulations and materials, they areengagedgenerating questions, predictions, and comparisonsthinking deeply about system structure and behaviorcollaborating with peersconstructing understandingdemonstrating knowledge gainedPart of a three-level series, Systems in Motion - Level B is designed for use with ages 8 and up.
