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
What is it and why do we use it?
A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water. It gives scientists a precise and comprehensive charting of the distribution and variation of water temperature, salinity, and density that helps to understand how the oceans affect life
Most everyone knows that the Arctic is located at the top of the planet and home to the north pole. But did you know the average winter temperature is minus 30 degrees Fahrenheit, and during summer, the temperature can climb to plus 50 degrees? That the Arctic is the only place polar bears live? And the Titanic struck an iceberg

Founded in 1984 with support from the National Science Foundation, IRIS is a consortium of over 100 US universities dedicated to the operation of science facilities for the acquisition, management, and distribution of seismological data. This weblink is directed to their education and public outreach resources.
POLENET (The Polar Earth Observing Network) is a global network dedicated to observing the polar regions in a changing world.
The project is focused on collecting GPS and seismic data from autonomous systems deployed at remote sites spanning much of the Antarctic and Greenland ice sheets. GPS and seismic measurements together provide a means to answer critical questions about ice
