Through investigation, you will determine which solution has the highest density.
Objective
To determine, through experimentation, which of a variety of solutions has the highest density.
Preparation
Background: The waters of the ocean are constantly moving in many different ways. The surface of the ocean rises and falls in rhythm. These movements, in the form of
Students are designated as the water or ocean currents, zooplankton, and bowhead whales. The zooplankton are informed that they are at the mercy of the currents. The currents are given instructions as to where to go during different times of the year (map). The whale pod is told that they need to breathe (raise hands above head to indicate
Students will build a simple plankton net from a nylon stocking, then (optionally) use it to collect plankton in ponds, lakes, streams, bays, oceans, or even aquariums.

This audio recording of bowhead whale calls was featured in a presentation by Stephen Okkonen at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
The attached Polar Oceans flyer, produced by the International Polar Year (IPY) Programme Office, provides summary information about the Polar Oceans and describes how the circulation in polar waters exerts a powerful control on the Earth's climate and carbon cycle. Activities attached to the flyer demonstrate the interconnectedness of marine life in the oceans and how the Polar Regions affect
The attached Lands and Life flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of terrestrial polar ecosystems, from southern cold maritime islands to dry continental deserts in Antarctica and from tree line across the continental tundra to remote northern islands in the Arctic. An attached activity allows students to build a small scale model of
Students experiment with a “blubber glove” to experience how insulation affects heat transfer, and how the adaptation of blubber helps penguins as well as seals, whales and walruses survive in bitterly cold waters.
Listen in to this radio interview on National Public Radio's program, "All Things Considered" with PolarTREC teacher Nell Herrmann. Nell describes her excitement about traveling to Antarctica and her role in a study of Antarctic seafloor organisms and their response to changes in water acidification and temperature. Nell outlines her plans for sharing the research team's findings with her students
