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? • ALISON website http://www.gi.alaska.edu/alison/ALISON_SITES_Map.html Wasilla, 2005-06 Seasonal Ice Growth and Snow Depth (m) http://www.gi.alaska.edu/alison/index.html Poker Flat Research Range, 2005-06 Seasonal Ice Growth and Snow Depth (m) http://www.gi.alaska.edu/alison/index.html Barrow, 2005-06 Seasonal Ice Growth and Snow Depth (m) http://www.gi.alaska.edu/alison/index.html Is it true, or just a lot of hot air? Let’s look at what is going on in Connecticut! www.ctclimatechange.com www.ct.climatechange.com 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. http://www.somers.k12.ct.us/%7Emporter/index.html The End… or Just the Beginning?
