In this activity, students will use data collected about two male arctic ground squirrels by researchers at Toolik Field Station in northern Alaska. Each squirrel had a lightlogger to record light intensity (lux) and an implanted data logger to record internal body temperature (°C). Students work individually or in pairs to analyze the data sets and interpret the results
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
Scientists use bathymetry to understand the ocean floor. This lesson is a basic introduction to bathymetry using salad trays to help students understand how bathymetric maps work.
Objectives
1. Students will be able to identify the advantages to using a bathymetric map.
2. Students will be able to transform a bathymetric map into a three-dimensional model.
3. Using just
We want students to develop the habits, traits, and qualities of effective scientists. What better way for them to learn what these traits are than by hearing from actual scientists? In this lesson, students watch video interviews with four Arctic scientists from the University of Alaska, notice what types of work scientists do on a daily basis, and make
One of the first things to understand about the Antarctic ecosystem is what kinds of animals actually live there. This lesson provides a basic introduction to important Antarctic wildlife and how they interact with each other.
Objectives
Students will be able to create a food web of the Antarctic ecosystem.
This is a one hour PolarConnect event with PolarTREC teacher Amber Lancaster and her research team aboard the RV Nathaniel B Palmer. They are studying the collapse of the Larson B Ice Shelf in Antarctica and its impact on the ecosystem of the Weddell Sea. Note: Due to satellite phone connection there are a few moments of dropped audio, the
