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
Lesley Anderson was connected with local California radio station KSON before and during her trip to South Pole, Antarctica as part of the PolarTREC program.

The Star News, a Chula Vista newspaper interviews Lesley Anderson about her experience studying neutrinos at the South Pole and her plans to bring the research back into her classroom.
Technology geared to the instruction and learning of science concepts, skills, and processes is instrumental to a deeper understanding of science phenomena and content.
Overview
This lesson is intended to introduce students to the concept of scientific exploration and investigation. Students will model the technology used in the Jellyfish in the Bering Sea expedition by using underwater cameras and tow
The Importance of Teacher/Researcher Collaboration
No book, movie or professional development I have experienced could have produced the effect of actually being in the field engaging in scientific research as a PolarTREC teacher on the “Jellyfish in the Bering Sea” expedition July 27-August 5, 2017. As the PolarTREC teacher, I was tasked with the role of disseminating the ongoing
This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
NASA’s Operation IceBridge uses remote sensing techniques to build a picture of parts of our world not accessible or easily observed by humans. Flying 1500 feet above sea and land ice, the science team uses LiDAR, Radar, Infrared imaging, and high resolution digital imagery to collect information about our polar regions year after year. In this classroom project, inspired and
NASA’s Operation IceBridge (OIB) flies airborne missions each year over both Polar Regions, collecting ice thickness and extent data on glaciers, ice caps, ice shelves and sea ice. This data is useful to many disciplines studying climate, weather, ocean circulation, sea level and many related fields. The National Snow and Ice Data Center (NSIDC) houses and organizes the data
