Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
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
Many students are familiar with topographic maps showing relief of land surfaces. In this lab they will produce their own bathymetric maps, the underwater equivalent. A bathymetric map shows sea floor features by contouring depths below sea level (instead of elevation above sea level as in topographic maps). Students will first probe depths in “Mystery Bay”, a box
This PolarConnect event with PolarTREC Teacher Bill Schmoker working onboard the US Coast Guard Cutter Healy was held with Centennial Middle School in Colorado. This event was closed to the public and does not have a Wimba archive.
Article about Bill Schmoker's upcoming PolarTREC expedition aboard the USCGC Healy in the Arctic Ocean. View the actual article at the Boulder Daily Camera Online.
This was a real-time event with PolarTREC teacher Casey O'Hara being broadcast from the South Pole Station, Antarctica. Casey presented on the IceCube telescope project and covered a bit about life at the South Pole station.
This article from the San Francisco Chronicle is about Casey O'Hara's upcoming expedition to Antarctica. It also includes some great photos from a pre-expedition icecream making lab. You can visit the article online here.
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
