Complete the following task by answering all the questions in the spaces provided.
Resource Development
If you show learners a picture of earth from space and ask them, what do they see, their responses will vary. Some key words to look for in their responses are: oceans, water, land, mountains, clouds, soil, rocks, plants, desert (and maybe rain, animals, people). When grouping the observed features, learners may come up with any combination of the following groups:
- Air (atmosphere) including rain and clouds.
- Water (hydrosphere) including oceans, lakes, rivers, etc.
- Soil (pedosphere) or land.
- Living things (biosphere) including plants, animals, people, etc.
- Snow or ice (cryosphere).
- Rocks (lithosphere); and
- Sunlight for energy.
At this point the emphasis changes slightly to how these features make Earth habitable and able to sustain life. Reasons given may include that Earth has:
- Water.
- An atmosphere with oxygen.
- Soil with nutrients.
- Carbon.
- Gravity.
- Sun that helps plants make food that we can eat; and
- Right temperature.
