This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
Podcast of the live TV interview with QATV journalist Joe Catalano. This interview is a follow-up to a previous discussion about the PolarTREC expedition.
Quincy Access Television interview: PolarTREC teacher Cara Pekarcik talks with Joe Catalano on the Currently in Quincy Program. The conversation includes descriptions of the PolarTREC program, a description of the research project and day-to-day activities as well as a discussion about student and community outreach.
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
Through activities, video observation, experimentation and the construction of a Remotely Operated Vehicle (ROV) students will learn about the chemical and physical properties of sea ice.
Objectives
Students will be able to answer main questions of where sea ice is, how it is formed, why the ice is important, how it is classified by indigenous people and scientists, how
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
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
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
Students will sort organisms found in the Bering Sea into food chains and gain an awareness of the flow of energy and nutrients in the Bering Sea Ecosystem.
Objective
Students learn about the different organisms that live in Alaskan waters by playing the Fabulous Food Chain Game. In playing the game, they become aware of the flow of energy
