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
Connecticut Science Framework
Content Connections
Strand One: Energy Transformations
Strand Three: Global Interdependence
Inquiry Connections
Laboratory inquiry
Science, Technology and Society (STS)
Literature inquiry
Energy Transfer & Transformations
• Describe the effects of adding energy to
matter in terms of motion of atoms and
molecules, and the resulting phase
changes.
• Explain how energy is transferred by
conduction, convection and radiation.
Assess Prior Knowledge
• Micro Lab Protocol
– Group students in triads
– Assign each student a number 1-3
– Choose one question/person to address
– Think in silence for 1 minute
– Respond in turn for 1 minute uninterrupted
Choose one question
• What is the difference between heat and
temperature?
• What influences the thermal conductivity
of a material?
• How are heat and temperature related?
How can we test this idea?
Introduction to Heat Flux
• 4 “warm up” demonstrations
• Student observations/explanations
• Extensions to IPY
Countdown to meltdown!
Balloon Demo
Flipping Your Lid
An Under Cover Operation
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 difference
Composition
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
International Polar Year:
What’s the connection?
Jigsaw Activity
• Select a candy and group yourselves
• Read the title of the article
• Jot down what you know about the
subject on graphic organizer
• Skim the article and record new ideas
• Share out your learning with mixed groups
• Record new ideas
Differentiate the Articles
• Vary entry level of reading
• Allow self selection of material
• Micro lab as pre-reading or post-reading
activity
• Provide a variety of graphic organizers for
pre-reading/reading/post-reading thoughts
Arctic Inquiry Investigations
How can we study the impact of global
climate change in the Arctic?
Measuring Heat Flux
Our Spatula & Cylinder
Sampling the
Snow
The density of the snow affects its insulating properties.
Moving the
Sample to be Stored
Calculating Density
Differences in Snow Densities
powdery snow vs.
packing snow
What happens when water loses
heat to surrounding materials
below 0o C ?
It Freezes!
Impact to the Environment
• What effect does climate change have on ice
growth?
• What effect does change in ice growth have on
the Arctic environment?
• What impact does this have on humans?

Is it true, or just a lot of hot air?
Let’s look at what is going on in Connecticut!

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.
