Analogs are used in science investigations to better understand systems we can’t access ourselves. In this lesson, students explore the Dry Valleys of Antarctica to better understand microbial communities on early Earth and what might have been possible on ancient Mars. Students will examine photographs, written descriptions, and artistic renderings of early Earth, the Dry Valley lakes, and
This article summarizes the research of cyanobacterial mats in Lake Joyce during the 2014 field season. It describes the importance of the mats to better understand Earth history and understanding of other planetary systems. Additionally, it describes the sediment trap experiement that will conclude in the next field season.
On 6 October 2014, Capital Public Radio in Sacramento, CA interviewed Dawn Sumner, Tyler Mackey and Lucy Coleman on connections between the research in Lake Joyce, Antarctica, and work by the Mars Curiosity rover. To listen to the interview, click here.
Students will use the TAMMNET project and accompanying PolarTREC resources to learn about seismology in the Antarctic, culminating in the creation of an annotated map using google maps.
Objective:
Students will understand the different ways mountain ranges are formed, and appreciate the questions unanswered about the Transantarctic Mountains. Students will also appreciate the ingenuity required for doing research in
This article and associated video describe the findings of researchers who undertook core drilling at Lake El’gygytgyn, a lake that sits today inside a basin formed by a meteorite that struck the earth 3.6 million years ago. An associated video allows us to hear the enthusiasm and details as researcher Julie Brigham-Grette describes the findings of this remarkable discovery.
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.
Plan and run a family fun afternoon or evening with several hands-on activities. Students help run the activity stations and share what they have learned about the Polar Regions. A great culminating activity for a unit on the Arctic, Antarctica, or both, and a fun way to involve families in the learning experience.
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
