Melting Ice And Sea Level Changes, Morton Sternheim
Melting Ice And Sea Level Changes, Morton Sternheim
IPY STEM Polar Connections
A simple experiment to demonstrate the effects of melting sea.
Thermohaline Circulation, Rob Snyder
Thermohaline Circulation, Rob Snyder
IPY STEM Polar Connections
Surface currents, such as the Gulf Stream, are pushed by the wind. Deep ocean currents, called the “Thermohaline Circulation”, are the result of changes in the density of water. In this activity you can investigate how differences in the temperature and salinity of water can produce deep ocean currents
Detecting Atmospheric Carbon Dioxide With Btb, Stephan Schneider
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.
Melting Ice And Sea Level Change, Morton Sternheim
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?
Brine Rejection Activity, Beth Caissie, Rob Snyder
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.

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 past changes …
Sea Ice Food Webs—Hands On Sampler Teacher Guide, Beth Caissie
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.
Glacier Goo Activity, Beth Caissie
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 to …

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

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 …
