Oftentimes called “ghost particles,” neutrinos can travel through nearly everything (the sun, the earth, you!) undetected. Because they are nearly massless, gravitational fields do not affect neutrinos; Similarly, because they are chargeless, electric and magnetic fields do not con affect neutrinos. This lack of interaction is advantageous for IceCube researchers – when they detect a neutrino, it is a
In this lesson, students will be introduced to the Standard Model, learning key vocabulary such as Fermions, Hadrons, Mesons, Baryons, Quarks, Leptons, particles, and anti-particles. In particular, students will come to understand what a neutrino is and why it is such a unique particle. This understanding connects to the IceCube Neutrino Observatory’s search for neutrinos in an effort to
Free community viewing of Taking Earth's Temperature -Delving Into Earth's Past followed by Q & A w/contributor Dr. Jason Briner. Organized by PolarTREC teacher, Tina Ciarametaro in her home community after her expedition to Greenland. Learn more here about the documentary Taking Earth's Temperature.
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
During Lesley Urasky’s expedition, “Glacial History in Antarctica”, the team collected rock samples which were taken back to the University of Washington to be dated using cosmogenic (exposure) dating. This method of radiometric dating measures the ratio of isotopes of Beryllium (9Be:10Be) produced by the interaction of cosmic rays with minerals in rocks. This lesson will introduce the student to
