Scientists in Siberia are seeing trends of more severe and widespread wildfires. Larch seeds are dispersed by wind. Experimentation is currently underway to determine distances larch seeds can disperse from viable, mature larch trees. Students will explore how various types of seeds are dispersed to get what they need to survive.
This lesson investigates the effects of different insulators (fur and blubber) on maintaining the body temperature of polar animals. Water balloons filled with warm water simulate the marine mammal. The blubber insulator will be simulated by covering the balloon in vegetable shortening. The fur insulator will be simulated by placing another balloon over the “marine mammal” and adding an
Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
In this activity, students will use data collected about two male arctic ground squirrels by researchers at Toolik Field Station in northern Alaska. Each squirrel had a lightlogger to record light intensity (lux) and an implanted data logger to record internal body temperature (°C). Students work individually or in pairs to analyze the data sets and interpret the results
This lesson allows students to learn about the Arctic through a challenging question and answer game format. Inspired by experiences in the Hidden Ocean 2016: Chukchi Borderlands expedition, the game includes “careers”, “animals”, “equipment”, “climate change”, and “geography” components. The game may be used as a learning tool, a review tool, or an assessment tool.
In this webquest, students use maps to relate global temperature change to changes in the range of insects and birds and projected changes in tree range. The activity could be used to teach a lesson via class discussion and/or written response; it could be completed by students in cooperative groups on paper or with shared computers; on the other
