New videography techniques have opened up the oceans' microscopic ecosystem, revealing it to be both mesmerizingly beautiful and astoundingly complex. Explore this hidden world that underpins our own food chain -- in the first-ever TEDTalk given by a fish ...
This lesson was written for the 2012 Arctic Ocean Ecosystem Workshop and was inspired by the research work conducted off the coast of Barrow, Alaska by researchers Steve Okonnen and Patricia Yager with PolarTREC teachers Lollie Garay and Chantelle Rose. Students will engage in a series of exercises to investigate seasonal change in the Arctic ecosystem based on authentic
In part one of this two-part lesson students work in pairs to explore the effects of salinity on ocean stratification using a simple plastic shoebox-sized container in which they create a mini-ocean environment. Students will apply what they learn in the lab setting along with information gained in several online articles to a basic understanding of the Global Conveyor
Coring trees is a way of learning about trees without cutting them down. When a tree is cored, the rings are examined to learn about the history and growth of a tree. In this lesson students will participate in a hands-on activity to help them investigate what information can be gained by studying and comparing tree core samples collected
Students will measure and analyze features of two different species of trees by using their cross-sections (cookies). Further analyses will allow students to graph their results and apply the knowledge gained to an understanding of tree growth, health and diversity.
Objectives
Students will use and understand the following terms: radius, diameter, circumference and area of a circle.
