Video Lesson: The Biogeochemical Cycle of Carbon

Video Lesson

Subject
Biology

Description of the video lesson
This video looks at the following topics:
- the carbon cycle in the ecosystem;
-photosynthesis
-breathing and respiration
-human activities and greenhouse gases
-global warming

Level of English
Basic English grammar and vocabulary listening and comprehension skills

Pre-requisites
Students should understand basic English grammar and vocabulary.

Language aims
This is a descriptive topic as well as containing technical details. Students should be able to talk about the topic, breaking it down to individual processes and then linking them together. They can use present and past tenses and should include keywords as nominated throughout the video. They should also be able to move from root words as nouns to verbs, e.g. respiration to respire.

Subject aims
In studying the biogeochemical cycle of carbon we consider certain areas and illustrate that the biology and chemistry of the processes are interlinked.
- the carbon cycle in the ecosystem;
-photosynthesis
-breathing
-human activities and greenhouse gases
-global warming.

We also realise that the carbon is largely recycling as carbon dioxide - not as pure elemental carbon.

Students' Difficulties
Difficulties may include translating the macroscopic - e.g. plants make food, the climate changes, etc. to the biochemical molecular level.

Students' Skills
Students should be able to describe natural processes like photosynthesis and respiration as well as combustion and show how they are interlinked in the recycling of carbon in nature.
- Understand that the three interdependent processes, photosynthesis, breathing and combustion, are the basis of the displacement of the carbon between the living and non-living component of the biosphere.
-Understand the reasons at the origin of global warming
