While most of the materials for the flux chamber are everyday items, teachers will need to purchase or borrow a carbon dioxide probe to use for the experiments.
Students can design and test their experiments using the flux chambers.
Students can analyze the importance of being able to measure carbon dioxide levels in a specific area.
Other resources related to the carbon cycle include thisvideo about how carbon dioxide gets into and out of the atmosphere, thisgame to help students visualize the carbon cycle, and thisinteractive book chapter with resources and data on short and long-term carbon cycles.
This resource is a step-by-step guide on how to create your own carbon dioxide flux chamber using everyday materials. These flux chambers can be used, in conjunction with a CO2 monitor, to do experiments that measure the output of carbon dioxide from a photosynthesizing plant. This resource is recommended for teaching.
