When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
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
Humans hold special relationships with the natural resources by which they are surrounded. These connections are increasingly being challenged by changing climate patterns, availability of resources, and societal changes. In this activity students will investigate the cultural importance of an Arctic plant or animal. Each student will create a carving and research traditional uses, geographic range, and natural history
Data collected from experimental manipulations of ecological processes can help us understand the natural world, and perhaps even help scientists predict how complex systems may change. At CiPEHR, (Carbon in Permafrost Heating Experimental Research) located near Denali National Park, scientists have collected and analyzed seven years of data to learn how increases in soil temperatures influence the carbon
This lesson is a modification of what Dave Hess and I, Stan Skotnicki, use in our Earth Science classes at Cheektowaga Central High School. It is an extension of our lesson on Celestial Motions as we track the apparent path of the sun across the sky at different latitudes. Prior to this Lab activity they would have already
In a “March Madness” game of survival of the fittest, will your microbe and its genes survive the test of changing conditions on Planet Earth and beyond? Students choose genes from a “toolbox” and pit their microbe against their classmates’, using critical thinking and argument writing to determine the microbe with the best chance of success. Based on PolarTREC
Permafrost puts extensive limitations on plant growth and building construction. Most students in the world are not exposed to this phenomenon and don’t have a clear concept of what it is or how it is at risk. This inquiry activity is designed to let them explore the impact of melting permafrost on a human structure.
