Activity 2.3: Evidence-Based Arguments for the Meadow Simulation (40 min)
Target Student Performance
Students develop arguments from evidence about possible patterns in relationships among mass of populations at different trophic levels in a simulated meadow ecosystem (the organic matter pyramid).
Resources You Provide
- (From previous activity) 2.2 Meadow Simulation Worksheet
- 2.3 Evidence-Based Arguments for the Meadow Simulation PPT
- 2.3 Evidence-Based Arguments Tool for the Meadow Simulation (1 per student)
- 2.3 Assessing the 2.3 Evidence-Based Arguments Tool for the Meadow Simulation
Prepare a computer and a projector to display the PPT and one copy of 2.3 Evidence-Based Arguments Tool for the Meadow Simulation for each student.
Remember that at this point in the Unit it is okay for students to have many unanswered questions and incorrect ideas. It is important that they are able to describe the organic matter pyramid as a pattern in ecosystems, but they should not be expected to fully explain it at this point. Use the 2.3 Assessing the 2.3 Evidence-Based Arguments Tool for the Meadow Simulation to get a sense for where students are in their ability to identify the main pattern in this unit: the organic matter pyramid.
