This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
This is a one hour webinar hosted by PolarTREC teacher Andre Wille at Toolik Field Station, Alaska. The work presented is part of the Arctic Ground Squirrel Study 2014.
This lesson was written for a Photography I course, to be taught in a lab with access to either a darkroom or computers/printers. The class has already spent ample time getting used to the basics of photography, learning to use their cameras as a creative tool, just as a painter might use a brush. This lesson could easily

The Center for Microbial Oceanography offers resources on education and outreach for K-12 teachers, undergraduates, grads & post-docs and related links. This is a great tool for lesson planning. In addition to outreach ideas, C-MORE offers kits for review and request.
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
