Part 1: Introduction to the Biomass Accumulation Model
Guiding Question:
- How does the Biomass Accumulation Model work?
** For background information and implementation suggestions see the GLOBE Biomass Accumulation Model Teacher Guide**
Materials:
- Computers with access to the internet
- Biomass Accumulation Model (download zip or run online from GLOBE Carbon Cycle website)
- If downloading zip file, you will also need the free iSee Player to run the model (available from iSee Systems)
- GLOBE
Biomass Accumulation Model Teacher Guide
Pre-requisites:
- Basic knowledge of modeling or systems dynamics (see GLOBE Carbon Cycle Systems Thinking &
Modeling teacher resources and/or Paperclip Simulation & Model)
- Basic knowledge of the global carbon cycle (see GLOBE Carbon Cycle website)
- Ability to use the iSee Player (if running Model from zip
file)
Estimated Time:
- 1 hour
What to do and how to do it:
- INTRODUCTION: Use a formative assessment technique (Frayer Model, KWL, etc.) to establish students' prior knowledge about systems, modeling, and/or biomass.
-
In response to students' prior knowledge, establish a
purpose for using the Biomass Accumulation Model to study
biomass and carbon storage at a particular site. Emphasize
the importance of computer models for scientists to
understand the behavior of complex systems and to predict
outcomes that cannot be measured directly.
-
View Biomass Accumulation Model screencast
tutorial with students to introduce the basics of the
model.
- Students Follow the instructions in Student Worksheet 1 found at the end of the GLOBE Biomass Accumulation Model Teacher Guide in order to explore the use of the model and to build their understanding of model inputs and outputs with respect to their study location.
- WRAP-UP: Record and review new terms and concepts on
overhead or blackboard. Make sure all students understand
what variables are contributing to the model results and how
this model study relates to carbon dynamics and climate
science. Discuss limitations of the model. What variables
were not included? (The Background section of the Biomass
Accumulation Model Teacher Guide provides a comprehensive
review of key concepts. Worksheet 1 can be used to evaluate
students' ability to use the model and identify essential
concepts related to the model).
Assessment
Assessment suggestions are located on page 7 of the GLOBE Biomass Accumulation Model Teacher's Guide. The Teacher's Guide also contains Teacher Versions of student worksheets.
