Why Is It Warmer? Human Causes

Theme: Environment

Grade: 7-9

Introduction

Global warming is a hot topic around the world. Many scientists who are concerned about global warming believe that we are creating dangerous changes in the Earth’s climate and think that world leaders need to address this issue immediately. Other scientists say that human society has not caused global warming. Instead, they think that Earth’s warming climate is a result of natural changes in our environment that are caused by solar activity, volcanoes, and other natural occurrences.

Who is telling the truth? What is causing global warming and how do we prevent it? Anyway, is global warming such a big problem anyway? What do you think?

Task

A United Nations forum will invite experts on both sides of the argument to present their views on global warming. This forum will provide the UN with the information they need to make an informed decision about the causes of global warming and to provide recommendations to the world’s leaders about what needs to be done to stop it or to deal with the resulting climate changes.

You are part of a team of scientists who works for an environmental research group. This team will go to the UN forum to tell them that global warming is a human phenomenon, and to ask them take action to create a plan that will limit the use of products that increase greenhouse gases. Your position is that without such regulations, humans can cause irreversible devastation to the planet. Your team must find information to support this position and you should be prepared to provide some examples of the impact global warming has on the environment. You and your fellow scientists must also be ready to argue against statements made at the forum that disagree with your position.

To complete this assignment, you will work in teams of four within each scenario, and your team must complete the following tasks:

1. Find data to support your position. Use the research guide (see your roles under Process below) to help you collect information.
   
   
2. Decide how to use the data you have found to support your position. Discuss this with your team, using the analyser to assist you. You will also create a chart or graph(s) using Microsoft Excel to illustrate your argument.
   
   
3. On a storyboard pad, storyboard template, or chart paper, create a storyboard to plan your PowerPoint presentation. The storyboard should include notes for you to refer back to during the debate. Think about how the other side may use the same information to present their argument and include information to counter their statements.
   
   
4. Create a PowerPoint presentation that emphasises the main points of your argument. Include your graph(s) in the presentation. Use PowerPoint’s note feature to add information to support your argument. Include a bibliography to cite the sources you used. It is optional to use any additional resources to support your team presentation. For example, you may produce flyers to distribute to the audience.
   
   
5. Participate in a forum to share your team’s presentation and listen to how the other teams present their positions. Be prepared to answer questions and support your own argument if learners who researched the other side of the debate ask you to defend your position.

Conclusion

By completing this activity you and your team should have gained a good insight into the issue of global warning not only from your own team's perspective, but also by listening to the arguments of the opposing teams. Now that you have heard different viewpoints, supported by facts, what is your opinion?
