Unit Plan: Exploring Ecosystems

Unit Overview

Grade Level: 5th Grade

Subject: Science

Duration: 4 Weeks

The unit "Exploring Ecosystems" is designed to engage students in understanding the complex interactions within ecosystems, including the roles of producers, consumers, and decomposers. Through hands-on activities, collaborative projects, and assessments, students will explore the characteristics of various ecosystems and the importance of biodiversity.
