Students decorate polysterene cups later to be submerged in the ocean. Subsequent activities have students consider the effects of water pressure and depth with respect to their cups.
Objective
Students will determine mass and volume of a styrofoam cup. They will calculate the density and research the depth of the Bering, Beaufort and Chukchi Seas. They will
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
What happens to the salinity in the Bering Sea during ice and no ice conditions? Does it change throughout the year and at different depths during different seasons? Create a model of the Bering Sea in ice conditions. Change the conditions based on seasonal changes to explore the effects of runoff on salinity.
Students are asked to predict what will happen to styrofoam objects lowered down to the bottom of the Bering Sea. Students make the appropriate calculations related to the actual experiment which took place on Maggie Prevenas' PolarTREC expedition.
Objective
Students will make hypotheses and calculations regarding deep sea experiments that took place in the Bering Sea on
This data plotting lesson compares different stratospheric ozone data collected at the South Pole in September 1969, September 1998, September 2008, January 1999, and January 2008. This ozone comparison activity allows students to make conclusions about the annual and seasonal ozone hole as well as overall ozone concentration changes over Antarctica. Students use authentic data collected at the
This data plotting lesson is about temperature changes throughout the atmosphere. The data was collected together with the ozone data in January 2008.
The temperature vs. altitude profile allows students to make conclusions about annual and seasonal temperature changes in the atmosphere up to about 35 kilometers in the stratosphere. The best part of this lesson is using
