Teacher explains the task to the students

Energy Transfer in an Ecosystem icon
Energy Transfer in an Ecosystem

Resource ID: txls075
Grade Range: 9
Subject: Science

All matter contains energy. Energy can be transferred from one object to another. Energy transformation can occur through the conversion of energy from one form to another. Energy is never created nor destroyed; it is always transferred and/or transformed. Students will demonstrate how energy is transformed and transferred in an ecosystem. To do this, students will create energy pyramids by stacking cups that represent organisms and available amounts of energy. Students will graph and analyze the data.
