Understanding the Biosphere Concepts

Mrs. Tyler introduces a lesson on the biosphere for grade seven natural science. She explains the meaning of 'biosphere' by breaking down the words 'bio' and 'sphere', and discusses how different parts of the earth interact to support life. Examples such as the ocean and sea plants are used to illustrate the concept. Students are encouraged to think of their own examples and participate in activities to reinforce their understanding.
