Teaching Outlines

  1. Understands the nill effects on environment by the human activity
  2. List out activity of humans .
  3. Understands the environmental pollutions
  4. Guess the effects of human activity on environment
  5. Reson out and understand effects of all types of pollutiuons and reson for it
  6. Understand global warming and its effects and remidies for it
  7. List out reson for acid rain and its effects and remedial messures for it

Notes for teachers

These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.

Activity No 1#The Greenhouse effect

  • Estimated Time-40 minutes
  • Materials/ Resources needed-Computer/laptop, projector, screen, PhET simulation
  • Prerequisites/Instructions, if any
  • Students have learnt about global warming.
  • Multimedia resources
  • Website interactives/ links/ simulations
  • PhET simulation on ‘The Greenhouse Effect’
  • Video on ‘The Greenhouse Effect’ by NASA Earth Observatory (Duration of the video- 3minutes 29 seconds)
  • How does global warming affect the environment? (Duration of the video- 5minutes 18 ---------watching first 3minutes of the video)
  • Process (How to do the activity)
  • 1.Review of the greenhouse effect using the video on ‘The Greenhouse Effect’ (How carbon di-oxide and water vapour cause greenhouse effect? How greenhouse effect maintain the surface temperature of the Earth?) 2. Using the PhET simulation to understand the mechanism of Earth's greenhouse effect.
  • Tab 1- The Greenhouse effect
  • Step 1- Varying the amount of greenhouse gas concentration in the atmosphere by using the slide bar on the right
  • Developmental Questions (What discussion questions)
  • What do you see happening?
  • In what direction, relative to Earth's surface, are all the yellow photons moving?
  • In what direction, relative to Earth's surface, are the red photons moving?
  • Which colour photons represent sunlight?
  • Which colour represent heat?
  • Step 2-
  • Evaluation (Questions for assessment of the child)

Project Ideas

  1. Visit a nearby small industry and list out its environmental hazards
  2. Prepare a album by using news paper ets about environmental pollution
  3. Comparising study for the number of vehicles with respect to the past ten years
  4. Campaigning about environmental pollutions and its effects , remedial measures
  5. Disscussingh the water pollution and warter resoures and its conservation
