Ecosystems and Their Importance in California

Rachel Kobak presents a video tutorial for a seventh-grade class on California ecosystems. The video covers the relationships in nature, focusing on plant and animal interactions in California. Students are encouraged to explore these relationships through a classroom scavenger hunt, where they investigate a mystery item and its ecological connections. The presentation aims to enhance students' understanding of ecosystems, the impact of drought, and human influence. An example using strawberries illustrates the process, and students are tasked with creating a chained ecosystem model.
