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
How glaciers in the polar regions respond to continued climate warming is of great concern. Changes in overall glacier velocities and calving dynamics have immediate impacts on sea level. Accurate predictions of how and when ice loss will occur are crucial to forecasting future environmental change.
This lesson results from experiences working in and around Kronebreen glacier in
This lesson was designed to teach pre-service teachers an inquiry-based approach for a science classroom. To give context to the activity, I used my experiences as part of “High Arctic Change 2014” for a lab activity. As such, the activity focuses on discovering how glaciers are formed and flow and how icebergs float in water. The materials can
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
What is it and why do we use it?
An Acoustic Doppler Current Profiler, or Acoustic Doppler Profiler, is often referred to with the acronym ADCP. Scientists use the instrument to measure how fast water is moving across an entire water column. An ADCP anchored to the seafloor can measure current speed not just at the bottom, but also at
