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
This geologic time calculator allows the user to manipulate the relativism of time to other markers. It builds from the classic analogy for illustrating the relative durations of parts of the geologic time scale is the yardstick.
This article describes PolarTREC teacher Nick LaFave's upcoming expedition to Toolik Lake, Alaska where he will be studying wolf spider populations with Duke University researcher, Amanda Koltz.
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 The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous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
Kevin Tavares and his fourth graders at Old Hammondtown School in Massachusetts built a website to share what they were learning with the rest of the world. Mr. Tavares installed a location tracking device on the page that assigns a red dot to the country of each visitor. The students wanted to get website hits from all seven continents so
Explore this interactive animation showing the size of Antarctica relative to other continents and countries. This resource was developed by the Italian educational project in the context of ANDRILL (Antarctic Geological drilling) research. The site is in Italian but the animation can be used without knowledge of Italian.
