Questions
What is global warming? What human activities might be contributing to it? What are some non-human factors?

Whatís ozone? Why are there holes in the ozone layer over the north and south poles? Is there a relationship between global warming and the holes in the ozone layer?

What do rising sea levels tell scientists about global warming?

Who are the scientists working on the problem? What actions have been taken at the international level to correct or slow global warming?

Future Plan

  1. Gather all your great ideas and research materials, brainstorm more great ideas with others, and make a plan for the future to answer this question:

What actions should we take to deal with global warming?

  2. Choose one of these styles for your presentation: pursuasive speech, science article, science fiction story.
  3. When youíre finished, present your plan to the class. The presentation should give an overview of the steps in your plan, explain who should be responsible for executing each step, and describe what costs and benefits are associated with the plan. You can enhance the presentation with audiovisual materials, models, and demonstrations. Presentations will be evaluated on:
  • Clear definition of the problem or need.
  • Clear presentation of facts and sources.
  • Organization (beginning, middle, and end).
  • Group participation and attentiveness during other presentations.
  • Effect on the audience.
