This lesson allows students to consider navigation around Antarctica, where longitudinal lines converge at South Pole. Through this study, students should learn about polar stereographic projection, satellites, navigation using various instruments, Antarctic geography, and NASA’s Operation IceBridge airborne mission. In the first part of this 55-80 minute lesson, students will be faced with a dilemma. Their task will be
NASA’s Operation IceBridge (OIB) flies airborne missions each year over both Polar Regions, collecting ice thickness and extent data on glaciers, ice caps, ice shelves and sea ice. This data is useful to many disciplines studying climate, weather, ocean circulation, sea level and many related fields. The National Snow and Ice Data Center (NSIDC) houses and organizes the data
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
PolarTREC Teacher Chantelle Rose is featured in this WDTN Channel 2 News Story before her departure on the USCG Cutter Healy for her Winter Sampling Expedition.
As the homepage of the website describes, "The beauty of the Arctic, its precious and fragile nature, its critical role in maintaining a stable climate for the planet, and the rapid rate of change that is occurring there must all be conveyed to the general public. Here, through digital story telling, we put a human face on science, life, societies
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska.
