La educadora informal de PolarTREC, Jocelyn Argueta, viajó al Polo Sur en 2019 con el Observatorio IceCube Neutrino y la Expedición Askaryan Radio Array. Creó una serie de YouTube Hielo Pequeño: Pedazos de la Antártida para explicar el viaje, la ciencia y la vida en el Polo Sur, tanto en inglés como en español. En esta serie
The PolarTREC Field Experience is amazing! PolarTREC (Polar Teachers Researchers and Educators Exploring and Collaborating) matches polar researchers with educators to highlight, and increase accessibility to, the science happening in some of the most fascinating places on our planet—the Arctic and Antarctic regions. It is an opportunity for educators to be completely immersed in the culture
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.
Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify

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
