Table \(\PageIndex{2}\): Unit conversion - GtC and Gt CO 2. To be more technical, atmospheric CO 2 concentrations are expressed in mol fraction of CO 2 in the dry air atmosphere. The ppm for CO 2 is hence μmol CO 2 per mole of dry air.. We have to put numbers on the components of the carbon cycle to quantitatively analyze changes in its components, otherwise, we can't know what is presently ...
atmospheric measurements (CO 2, oxygen (O 2) and 13CO 2). For 1980 to 1989, the ocean-atmosphere flux is estimated as −1.9 ± 0.6 PgC/yr and the land-atmosphere flux as −0.2 ± 0.7 PgC/yr based on CO 2 and O 2 measurements (negative signs denote net uptake). For 1990 to 1999, the ocean-atmosphere flux is
Introduce the concepts of a carbon sink, carbon source, and carbon release agent (see vocabulary section at the beginning of this lesson). Have students identify and label each part of their carbon cycle as a source, sink, or release agent. Ask students why these might be important factors to identify.
13 Απρ 2021 · Use this lesson plan with your 11–14 students to engage them with the carbon cycle. Start off with the starter slide, using some simple questions to probe prior knowledge. As the first main activity, have students play the carbon cycle game, taking on the role of a carbon atom.
The carbon cycle shows how carbon moves through all four spheres of Earth. Sketch some of the interactions that connect the movement of carbon through the spheres.
13 Απρ 2021 · Students take on the role of a carbon atom as it cycles through the Earth to simulate the carbon cycle. Download the materials as MS Word or pdf. Lesson plan and accompanying resources. An example lesson on the carbon cycle including starter slide, carbon cycle game, follow-up activity and consolidation questions.
It can be aerobic (needs oxygen) or anaerobic. Photosynthesis is the process by which plants/algae use energy from the sun to transform carbon dioxide and water into glucose (sugar) and oxygen. b) Write the word equations for these processes.
