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 |

Objectives-
|
* 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?"� |

Introduction-
| Distribute the Student Reading: The Temperature of the Earth, for
students to read as homework or in class. |

|
|
Practice-
- Activity 1: Lead students through slide show, reviewing key information
from the background reading, probing for understanding, and presenting
new information using the Teacher Guide.
- Activity 2: Introduce video activity. Lead students though decoding
of the two video clips using information in the Teacher Guide and
the Student Worksheet, Activity 2 on decoding the video clips.
- Activity 3: Distribute Student Worksheet, Activity 3: Trust and
Sponsorship. Lead discussion of credibility, sourcing and bias using
questions in the Teacher Guide.
- Activity 4: Lead the Take a Stand activity using the questions in
the Teacher Guide. |
