Ecosystem Interactions and Energy Flow

This video tutorial for fifth-grade students covers the unit on matter and energy in ecosystems. It explains how energy flows through ecosystems, starting from the sun, and how it is transferred through food webs and chains. The tutorial also covers photosynthesis, emphasizing that plants get most of their needs from air and water. Essential questions and learning goals are discussed, along with a detailed unit plan that includes activities like dissecting owl pellets, conducting plant experiments, and researching decomposers. The video concludes with assessment strategies and encourages students to explore further resources.
