International Polar Year

Marjorie Porter, Somers High School Mary Anne Butler, CSDE

Program Goals

• Familiarize participants with International Polar Year (IPY)

• Demonstrate connections between polar research and the CT Framework

• Practice inquiry activities with IPY emphasis

• Provide resources for your classroom

International Polar Year (IPY) 2007-2008• Coordinate a campaign of polar

research

• Initiate a new era of polar research

• Emphasize the connection between the polar regions and the rest of the globe

• Educate the next generation

Thermal Conductivity

Heat will flow from an object with higher thermal energy to another of

lower thermal energy.

The rate at which heat will flow between two

objects varies, and depends on many

factors: Temperature

differenceComposition

Proximity to each other

What Have We Learned?

•Heat moves from an area of high thermal energy to an area of low thermal energy

•Different materials transfer heat at different rates

•Heat transfer takes place by conduction, convection and radiation

Political Cartoons and the Inquiry Standards

The CT Science Framework• Strand III: Expected Performance D 23.

– Explain how the accumulation of carbon dioxide in the atmosphere increases Earth’s “greenhouse effect” and may cause climate change.

• Inquiry Standards: Expected Performance D INQ.2 – Read, interpret and examine the credibility and validity

of scientific claims in different sources of information.
