This lesson was created by 2017 PolarTREC teacher Steve Kirsche who took part in the Dynamic Observations of the Microstructural Evolution of Firn expedition. The lesson is intended to introduce students to the concepts of isostasy and postglacial rebound through a demonstration and related instruction. Students will then see how postglacial rebound is an important factor when assessing the
This lesson is intended to introduce students to the concept of using ice core samples to learn about the past. Students will be “collecting” a sample from a model of ice. They will then evaluate the sample to see how the layers change as the depth changes.
Objectives
At the completion of this lesson, students will gain a greater
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
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
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
