Lesson A5 - Learning more about carbon cycle transitions - photosynthesis and respiration
Natural sciences / Physics / Chemistry
Activity: 1h (+ a few hours to let the experiments run)
After the introduction to the carbon cycle provided by the last lesson, this worksheet illustrates, through experiments, how carbon moves between two reservoirs – plants and atmosphere.
During this lesson, students will learn that:
Plants capture CO2 from the atmosphere through photosynthesis, and release CO2 into the atmosphere through respiration.
Photosynthesis occurs only in the presence of light, while respiration occurs in both light and darkness.
Photosynthesis plays a major role in the carbon cycle at a global scale.
