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
To learn about the effects of air pollution on Sea Ice. This can be a library/computer lab-based activity.
Procedure
Teacher:
1. Mix up a 3.5% solution of NaCl. Make enough "sea-ice" cubes for each pair of students
2. Make another class set of ice cubes with tap water. Leave the ice in the freezer until after the
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
Procedure
1. Use the table in attached PDF to record your data.
2. Put 100 mL of 3.5% NaCl solution into a 250 mL beaker.
3. Attach 2
In this one hour webinar PolarTREC teacher Tim Spuck explains his work with the NASA IceBridge Project, the largest airborne survey of Earth's polar ice ever conducted.
This PDF handout and activity provides background information about polar weather and climate followed by an activity to help students consider their own local weather vs. polar weather. Students will observe the weather where they live and report on basic meteorological data such as air temperature, precipitation, wind etc. and use a weather map to compare their local weather to
University of Alaska Fairbanks Professor Katey Walter Anthony takes us onto a frozen lake in Fairbanks, AK to demonstrate why methane gas has "exploded" onto the climate change scene.
Permafrost is a key cryospheric component and of global interest for better understanding climate change. This short film presents an overview of permafrost on Earth and focuses on the International Polar Year (IPY) activities of a research group from the University of Lisbon and its international partners.
