Discuss and debate the evidence for the Greenhouse Effect. Develop a set of criteria for determining whether the Greenhouse Effect is real. Discuss how we might solve the problem of a Greenhouse Effect if it exists. Activity Description Students work in small groups collecting information on the Greenhouse Effect, and evidence for and against the possibility this phenomena exists. This is followed by a debate about whether the earth is in fact warming up due to the Greenhouse Effect.
Students use the data they have collected to support their positions.
Following this discussion, the focus shifts to political and environmental policies that might exacerbate the Greenhouse Effect, and a whole-class discussion of the possible impact of the Greenhouse Effect. Students begin by studying the Greenhouse Effect, using printed and on-line resources. As students research the Greenhouse Effect, they should be collecting evidence that supports or refutes the theory. As they visit these Websites, students should also be identifying what effect global warming might have on the earth, and what possible solutions might exist to any Greenhouse Effect. The groups gather to participate in a debate about the scientific merits of the Greenhouse Effect.
