1. Topic-
Global Warming: Fact or Myth?
2. Content-
Global Warming: Fact or Myth? relies on a student handout and an interactive slide show to teach core knowledge about climate science, the Earth's climate record, and evolving methodologies for determining global temperature. Students then
analyze and decode two film clips that use the same hockey stick graph to argue opposite points. Finally, students will explore issues of trust and sponsorship in an activity concerning the credibility and bias of information about controversial scientific subjects like global warming. The lesson will take about 60 minutes.

Key vocabulary: age of instrumentation, proxy data, hockey stick graph, IPCC, sponsorship, global warming, ice core data, bore hole pollen data, tree ring data, coral core data, ocean sediment core data, scientific corroboration
* Students will develop a clear definition of global warming.
* Students will review sources of data that are used to reconstruct the Earth's climate record and will identify discernible, cyclic patterns.
* Students will understand that Earth's climatic systems are dynamic and ever changing.
* Students will recognize agreement among various data sets and methodologies that have been used to determine the Earth's climate history and temperature record.
* Students will understand the debate concerning whether the temperature spike that has occurred recently is an anomaly.
* Students will identify bias found in media portrayals of the science of global warming.
* Students will develop a personal answer to the question, "Is global warming happening?"
