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
I spent a month on a boat in the Arctic as part of the 28 member Science Team that lived and worked alongside the 53 member Crew of the Canadian Coast Guard Ship Louis S. St. Laurent, a 392 foot icebreaker out of St. John's, Newfoundland
Before leaving for the South Pole in late 2009, I received many suggestions for things to try down under. Liz Ratliff’s math classes suggested we try making ice cream! So, before I left, I had my students follow her recipe to make ice cream in our classroom in balmy California. After arriving at the pole, I was able
Students will individually weigh a random sample of pennies. The data will be graphed to look for patterns, then explanations will be sought to explain these patterns. Some of the key ideas are using graphical representations of data to help identify patterns. This is a key concept in all sciences, including in the IceCube Neutrino Observatory - data
FAIRBANKS — A group of high school science and math teachers who could help unlock the secrets of the universe were in Fairbanks last week. The five teachers, who come from all over the Lower 48 as part of the Knowles Science Teaching Foundation, were training for the construction of the IceCube Neutrino Observatory, a telescope located at the South
About this time next year, Casey O'Hara, Carlmont High School physics teacher, will experience extreme subzero temperatures, 24 hours of intense sunlight and 10,000 feet of elevation. He'll travel to desolate Antarctica as a member of the largest research project of its kind - the construction of IceCube, the world's biggest telescope for detecting subatomic particles.
