In a food chain, producers and consumers transfer energy throughout an ecosystem. In this activity designed for 3rd-8th graders, students use a game of tag and a computer model to understand energy transfer through an ecosystem, and predict how changes in species functions and interactions can impact the system.
Note: Proposed NGSS alignment and 5E lesson structure (less Evaluate) are included in the activity guide. This activity was originally developed for Merced County Office of Education's TEAM-E Science Training for elementary and middle school teachers.
