This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Students will engage in a hands-on activity to help them consider what students in a tropical climate do to prepare for recess compared with students who live in the interior of Alaska.
Objectives
Students will:
* Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska.
* Learn
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
Students will sing a song and engage in an active game to learn more about ice algae and its role in the arctic ecosystem.
Objective
Students will learn about the arctic ecosystem, particularly the roles of ice algae, plankton, krill, fish, birds, seals, whales and polar bears through song and active participation.
Students will sing a song about the Bering Sea ocean ecosystem.
Objective
To sing a fun science-themed song!
Preparation
* Teach students about the Bering Sea ecosystem or have them review journal entries from Maggie Prevenas’ PolarTREC expedition (see Resources section for address).
* Hand out song sheet or project words onto a screen
Students will create a bookmark to help them remember that diatoms (ice algae) are the main producers in the Bering Sea ecosystem.
Objective
To create a tangible reminder of how the Bering Sea ecosystem's main producers (diatoms and ice algae) use sunlight and transfer that into food energy for use by most other creatures that live there
