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.
1. Use models to predict chlorophyll levels in the global oceans
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
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
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
PolarTREC teacher Nell Herrmann writes a compelling article for Town and Gown, the local newspaper in her home town of State College, PA. Nell reports on her adventures with a team of scientists in Antarctica and the profound way in which her journey has influenced her both personally and professionally. Note: The online article starts on p. 50 of the
The attached Lands and Life flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of terrestrial polar ecosystems, from southern cold maritime islands to dry continental deserts in Antarctica and from tree line across the continental tundra to remote northern islands in the Arctic. An attached activity allows students to build a small scale model of
The Polar Resource Book - Polar Science and Global Climate: An International Resource for Education & Outreach - was written to ensure that the efforts catalyzed by the International Polar Year (IPY) will continue to inspire educators, students, and emerging polar researchers with a shared commitment to outreach and education.
This 250 page book edited by Bettina Kaiser and others
Icy IPY activities can be downloaded in word documents and tried in your classroom. From 'Blubber Gloves' to 'Experiments with Ice and Snow', there are a wealth of different activities to introduce students to the Polar Regions or complement their existing knowledge of the Poles.
The International Polar Year is a large international effort that has involved over 200 projects
Students will observe how soils and rocks of different densities behave in wind and in water. They will make predictions and careful observations as they learn about sediment transport and sediment rates in streams and rivers.
