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.

In parts of the northern Arctic region, the delicate balance of the food chain depends heavily on the diminutive copepod Calanus glacialis. This herbivorous Arctic zooplankton species is specially adapted to melting sea ice and the blooming of a few small algal species.

The Circumpolar World introduces students to the landscape, peoples and issues of the circumpolar region. This module gives a brief introduction to the physical features and processes of the Arctic region and highlights the significant factors that influence those features and processes. Developed by Bruce Forbes and Steve Young.
This module gives a general overview of environmental issues that affect the Arctic, including climate change related themes. Compiled by Ake Bjorke, Lars Kullerud UNEP/GRID-Arendal, and Olav Hesjedal
