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
The Yale Climate Forum released this YouTube video on Permafrost in 2013. The causes and effects of melting permafrost are explained and linked to larger phenomena. Visit the Yale Climate Forum Website to learn more.
Researchers at the University of Alaska Fairbanks are studying the East Siberian Arctic Shelf region and finding the seafloor there holds vast stores of frozen methane and is showing signs of instability and widespread venting of the powerful greenhouse gas. In this video University of Alaska Fairbanks scientist Natalia Shakhova discusses the East Siberian Arctic Shelf area.
In an explosive clip from the BBC's landmark series, scientists drill into a frozen lake to ignite methane gas that is trapped in bubbles beneath the surface. Do greenhouse gases pose a signficant threat to our planet? Dr Iain Stewart assesses the dangers.
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.
From NASA, in this animation, the Arctic sea ice and seasonal land cover change progress through time, from September 1, 2009 when sea ice in the Arctic was near its minimum extent, through March 30, 2010. The animation plays at a rate of six frames per day or ten days per second.
Ever wonder why ice cubes float? I can tell you why ice floats in two words. Archimedes' Principle. Of course, Archimedes' Principle takes a bit more explaining. Let's make sense of it with science! This has been presented by Bayer Corporation's national education program, Making Science Make Sense.
