The Carbon Cycle

Created using Comic Life

Learning Intention: Students will understand the processes involved in the carbon cycle – photosynthesis, respiration, decomposition, combustion and fossil-fuel formation.

Success Criteria: A product that demonstrates their understanding by providing an explanation of each of these processes.

Your assessment task for this unit of work is to produce an artefact that explains your understanding of the carbon cycle. It might be a poster, video, Voicethread, cartoon or slideshow. You could use Comic Life, ToonDoo, a common-craft style video or another tool. Make sure you include the following processes:

  • Photosynthesis – green plants use sunlight to convert carbon dioxide and water into carbohydrate (glucose) that is used by all other living organisms as the source of food. (absorbs CO2 and H2O and releases O2)
  • Respiration – all living organisms (with the exception of a few bacteria) use oxygen to convert carbohydrates into energy, releasing carbon dioxide and water into the atmosphere. (Requires O2 and releases CO2 and H2O)
  • Decomposition – Bacteria and fungi break down organic matter (leaves, wood, dead animals etc) into carbon dioxide and water during respiration.(Requires O2 and releases CO2 and H2O)
  • Fossil Fuel formation – Oil, coal and gas are formed after millions of years under extreme pressure and high temperatures, from once living organisms such as trees and microscopic algae.
  • Combustion – wood, gas, oil, coal and other carbon-containing compounds can be burnt with oxygen to produce carbon dioxide. (Requires O2 and releases CO2 and H2O)
