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
The website, Ice Stories, features short interviews and other interesting content live from the polar regions. This weblink has a short video interview of PolarTREC teacher, Craig Beals, while taking part in a PolarTREC expedition with Barry Lefer at Summit, Greenland.
Maggie Prevanas joined scientists in the Bering Sea where sampling to measure the productivity of the Bering Sea Ecosystem was conducted. Maggie learned about the role microscopic organisms, diatoms, play in algae blooms, carbon cycling, and global warming. Maggie developed a lesson using scientific illustration to introduce diatoms to her students.
In this lesson, students learn about what archaeologists do and then practice implementing these skills with "real artifacts".
Objective
Students will:
* be able to define an artifact and an archaeologist.
* use evidence to support their decisions about the origin and use of an unknown item.
The study of rock and sediment layers, or stratigraphy, can be used to introduce students to the fundamental principles of geology and to lead into the idea of geologic time. In this lesson, students are introduced to Nicolas Steno's 3 major laws of stratigraphy: the law of original horizontality, the law of superposition and the law of lateral
