In this fifth-grade unit on interrelationships in ecosystems, students investigate the apparent disappearance of the body of a dead raccoon over time.   Their findings lead them to uncover the role of decomposers in this process, as well as the role of decomposers in the disappearance of plant debris over time. Students ultimately track down where the materials come from that all living things need for repair and growth and where the energy comes from that they use to move and stay warm.   



The storyline skeleton is now available.  Additional resources for the 1.0 version coming soon.

Here is a link that let you take a sneak peek at one class's journey through the start of storyline (from the second round of piloting - the Beta pilot).
