The following presentation was given by Dr. Patricia Yager at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska. The presentation outlines Dr. Yager's work in biological and chemical oceanography, and focuses on the feedbacks between climate change and marine ecosystems at different locations around the world.
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
Students will learn about adaptations that allow fish to survive the frigid waters of Antarctica and will make calculations to demonstrate how they survive these conditions.
Objective
* Students will determine how much antifreeze an Antarctic fish needs to lower the temperature of it's body fluids to -2.5°C. *
* Students will develop an experimental procedure to conduct their
The journal assignment involves students in current science research. Through the teacher’s journals, they will learn about how the research teams work together, design their research, tools that are needed and how they live and work in an extreme environment.
Objective
Students will be able to:
1. Understand how scientific research is conducted in an extreme environment
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
This is presentation provides an overview about sea ice in Antarctica as presented by Dr. Patricia Yager. She has slides about the daylight and seasons and related sea ice concentrations. She also has several slides about sea ice as a habitat and about the types of organisms associated with the sea ice. The main part of this presentation focuses on
