Ecosystem Energy Detectives

Grade 5Science10 days

The 'Ecosystem Energy Detectives' project is a comprehensive learning experience for 5th-grade students, focusing on the journey of energy through ecosystems from the sun to plants and various organisms. Through hands-on activities like photosynthesis experiments, constructing food chain models, and exploring decomposers, students gain a profound understanding of the roles of producers, consumers, and decomposers in energy flow. The project aligns with Next Generation Science Standards and encourages students to reflect critically on their learning progress and the pivotal role of the sun in sustaining energy cycles across ecosystems.

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
