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?
Introduction to Heat Flux • 4 “warm up” demonstrations • Student observations/explanations • Extensions to IPY
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
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?
Differences in Snow Densities powdery snow vs. packing snow
What happens when water loses heat to surrounding materials below 0o C ?
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? • ALISON website

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