Albedo Effects In Polar Regions, Morton Sternheim 2010 University of Massachusetts - Amherst

Albedo Effects In Polar Regions, Morton Sternheim

IPY STEM Polar Connections

•Why are Polar Regions more affected by global warming than other parts of the globe? •One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. •This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. •Increasing vegetation on land also has a similar positive feedback effect.


Globe Walk, Rob Snyder 2010 University of Massachusetts - Amherst

Globe Walk, Rob Snyder

IPY STEM Polar Connections

A “Globe Walk” can be used as a demonstration or classroom activity to guide students toward a better understanding of the affects that Earth’s axial tilt, rotation on Earth’s axis, and orbital motion have on the angles of incidence of sunlight, the lengths of daytimes, and solar insolation.


Detecting Atmospheric Carbon Dioxide With Btb, Stephan Schneider 2010 University of Massachusetts - Amherst

Detecting Atmospheric Carbon Dioxide With Btb, Stephan Schneider

IPY STEM Polar Connections

A study of the concentration of carbon dioxide gas in air samples requires an understanding of effective sampling techniques, the use of pH indicators, an understanding of chemical reactions that result on the formation of acidic compounds, and an understanding of the chemical processes that contribute to the composition and characteristics of Earth’s atmosphere.


Atmospheric Co2 And Temperature. What Is Normal?, Beth Caissie, Julie Brigham-Grette 2010 Iowa State University

Atmospheric Co2 And Temperature. What Is Normal?, Beth Caissie, Julie Brigham-Grette

IPY STEM Polar Connections

–How much of a change in CO2 concentration and other GHGs is natural? –What is the normal range of CO2 and temperature variability? How is normal defined in this context? –What is the relationship between CO2 and global temperatures?


Build A Remote Sensing Satellite, Rob Snyder 2010 University of Massachusetts - Amherst

Build A Remote Sensing Satellite, Rob Snyder

IPY STEM Polar Connections

•Build a model of a remote sensing satellite. •Use your model of a satellite to transform reflected visible of different frequencies into electrical signals with different voltages. •Use different colors of paper to calibrate the model. •Create a model of a landscape using three different colors of paper. •Create a “false color” image of the model of a landscape (if time permits).


Polar Remote Sensing, Beth Caissie 2010 Iowa State University

Polar Remote Sensing, Beth Caissie

IPY STEM Polar Connections

•Satellite sensors specialize in collecting data about specific wavelengths The Geostationary Operational Environment Satellites (GOES) operated by NASA, NOAA, and the U.S. Department of Commerce provide continuous monitoring of weather conditions. Orbiting the Earth’s equatorial plane at a speed exactly matching the planet’s rotation, satellites in the GOES network seem to hover over fixed spots. They monitor atmospheric conditions that lead to hurricanes, flash floods, tornadoes, and hail storms.

Caribou, Whales, Andenvironmental Variability, Craig Nicolson

IPY STEM Polar Connections

How many caribou are there? Increasing or decreasing? Carrying capacity? How do we measure habitat quality?? Satellite imagery. Whale migration patterns. Activities on caribou and whales. Also, see http://www.nfb.ca/film/being_caribou/ a video entitled Being Caribou..


Carbon Travels Game, Marie Silver 2010 University of Massachusetts - Amherst

Carbon Travels Game, Marie Silver

IPY STEM Polar Connections

Carbon cycle game.

Proportions for this activity are based LOOSELY on data from the Exploring the Environment website http://davem2.cotf.edu/ete/modules/carbon/effig11_full.html

They have a brief overview of the carbon cycle at http://davem2.cotf.edu/ete/modules/carbon/efcarbon.html


Brine Rejection Activity, Beth Caissie, Rob Snyder 2010 Iowa State University

Brine Rejection Activity, Beth Caissie, Rob Snyder

IPY STEM Polar Connections

As salt water freezes, the salt is pushed out of solution through channels in the ice. This process is called brine rejection or brine exclusion. These channels are often used as microhabitats by ice algae, zooplankton, and even tiny fish. You can easily demonstrate what these channels look like.


Melting Ice And Sea Level Change, Morton Sternheim 2010 University of Massachusetts - Amherst

Melting Ice And Sea Level Change, Morton Sternheim

IPY STEM Polar Connections

Global warming can melt snow or ice on Greenland, Antarctica, and other land areas. It can also melt floating ice in the Arctic Ocean. How do the two cases compare in changing sea levels?


Glacier Goo Activity, Beth Caissie 2010 Iowa State University

Glacier Goo Activity, Beth Caissie

IPY STEM Polar Connections

We provided the students with background information about what a glacier is, where they are, how they move. Then split the students into four groups each tasked with a question to answer through experimentation

Group s 1 and 2: How does temperature change the way a glacier flows? (we provided frozen, and room temperature goo, and a microwave for heating the goo)

Groups 3 and 4: How does friction or obstacles change the way a glacier flows? (we provided different pvc tubes—tubes with nothing done to them, tubes with paintable sand applied to them, and tubes with rocks glued ...


Play Doh Coring Sampler Teacher Guide, Beth Caissie 2010 Iowa State University

Play Doh Coring Sampler Teacher Guide, Beth Caissie

IPY STEM Polar Connections

Sediment cores are one of the most valuable types of samples for researchers who would like to learn about past climate or ecological changes. Cores can be retrieved from lakes, marshes, swamps, fields, and the ocean. The layers often reveal striking changes in color (see photos) reflecting changing sediment composition (i.e. more clay deposition or more microfossil s). This easy activity illustrates the basic geologic principle that horizontal layers of sediment become older the deeper you go below the Earth’s surface (Law of Superposition). Each layer contains sediment, fossils and organic matter etc. that can inform us about ...


Sea Ice Food Webs—Hands On Sampler Teacher Guide, Beth Caissie 2010 Iowa State University

Sea Ice Food Webs—Hands On Sampler Teacher Guide, Beth Caissie

IPY STEM Polar Connections

This activity is a variation on a food web game that I’ve seen played many times before, but it is adapted to reflect a sea ice food web and show the many organisms that are intimately connected to polar bears.

Teacher’S Guide: Penguins Of Antarctic Region, Marie Silver 2010 University of Massachusetts - Amherst

Teacher’S Guide: Penguins Of Antarctic Region, Marie Silver

IPY STEM Polar Connections

These activities help to connect science learning with real world issues through a study of the Antarctic region. By studying the penguins of the South Pole region you can tap students’ interest in a charismatic macrospecies through demonstrating their adaptation to ongoing climate changes and human activity. A number of current research projects at Antarctic research stations can be accessed online and the data used to demonstrate key concepts of feeding behavior, migration, breeding and population dynamics. The attached activity is in three parts and includes one hands-on demonstration, several mapping exercises and some data interpretation. These activities also provide ...


Seismic Investigation And Attribute Analysis Of Faults And Fractures Within A Tight-Gas Sandstone Reservoir: Williams Fork Formation, Mamm Creek Field, Piceance Basin, Colorado, Sait Baytok 2010 University of Colorado, Boulder

Seismic Investigation And Attribute Analysis Of Faults And Fractures Within A Tight-Gas Sandstone Reservoir: Williams Fork Formation, Mamm Creek Field, Piceance Basin, Colorado, Sait Baytok

Geological Sciences Graduate Theses & Dissertations

The seismic-reflection characteristics, distribution and orientation of faults, and fracture intensity of the Williams Fork Formation at Mamm Creek Field vary stratigraphically and with lithology and depositional setting. The fluvial, marsh, and shallow marine deposits of the Williams Fork Formation were deposited within alluvial-plain, coastal-plain, and shallow-marine environments. The deposits produce significant amounts of natural gas from Cretaceous-age tight-gas-sandstone reservoirs that are moderately porous but exhibit low matrix permeability. Faults and fractures provide conduits for gas migration and enhance permeability and reservoir productivity.

Key stratigraphic units, fault and fracture characteristics, fracture intensity, and the controls on fracture distribution were evaluated ...
