This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
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
The title of this lesson, 'Ssssno Seals' is a play on words. Will the ice seals survive? Yes or No? Paul Lukosi is a high school teacher in the lower Yukon River Delta, 6 miles from the Bering Sea...as the slough goes. The village he teaches in is heavily focused on family and culture, and has survived for thousands of
This lesson came out of a desire to connect the plankton research that I did during the 0902 Healy cruise with my young "researchers" back in Washington, DC. I wanted them to understand that plankton not only feed the Arctic but that much of the world relies on these little critters that come to life for us when we look
This series of three labs challenges students to think about the role of plankton in different ecosystems and waterways in the world. By modeling the research methods of scientists on the Healy icebreaker, students can conduct a small-scale change study to examine reproductive behavior of an isolated type of local plankton.
Students will become familiar with the anatomy/physiology, habitat and lifestyle of puffins. On the 2009 Healy Icebreaker expedition the wildlife survey team was primarily interested in bird diversity and population in the Bering Sea. Puffins were spotted during the cruise, especially feeding in and around Dutch Harbor, Alaska.
Objective
* Students will learn about the unique nature of puffin
This lesson is intended to have the students think about the animals of the Arctic and which ones they think are the largest. This will help with misconceptions of some animals being smaller than they think and you sneak in the scientific method and measuring skills while doing this lesson. Students will love actively participating and comparing themselves
Case studies provide a brief overview or examination of events that impact or alter the way people function and live day to day within the human and physical environment. They help by providing students with “real world” examples that relate to the theoretical content they are studying.
Objective
Students will prepare a case study illustrating the impact
Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska. Learn several consequences caused by sub zero temperatures. Create awareness that people are able to prepare for a cold environment by adding layers of clothes.
Objective
Compare what students in a tropical climate do to prepare
