Students will understand how the increasing levels of carbon-dioxide in oceans affect shelled marine animals. They will carry out a student-developed investigation on how increasing ocean acidification affects these animals.
Objectives
The objective of this lesson is for students to assess how increasing levels of atmospheric CO2 affect marine organisms. In addition, they will devise an experiment to test
Students will find an expedition within the PolarTREC archives and use the research to make a video explaining why studying polar science is important.
Overview
PolarTREC supports teachers on expeditions with real scientists to study in the field. Studying in the Arctic and Antarctic environments can be a harsh and rewarding experience. I participated in Operation IceBridge, an aerial study
Most students, regardless of their grade level, live “in the moment,” concerned only with factors and issues that have an immediate and direct impact on their lives. This is, to a large degree, understandable given the pressures, demands, responsibilities and constraints placed on students during their high school academic years. However, as teachers, we are required to not only
This lesson is intended to help students make connections to polar science while discovering how and why sea ice drives deep ocean currents. Students will also learn key terminology related to sea ice and using actual salinity content charts, will graph a typical sea ice core’s salinity as it relates to depth.
This lesson was created by 2017 PolarTREC teacher Steve Kirsche who took part in the Dynamic Observations of the Microstructural Evolution of Firn expedition. The lesson is intended to introduce students to the concepts of isostasy and postglacial rebound through a demonstration and related instruction. Students will then see how postglacial rebound is an important factor when assessing the
To begin the process of educating my students on my upcoming expedition to Antarctica, I introduced an activity entitled, “Questions about Antarctica…It’s What’s for Dinner.” In this assignment, small groups were asked to develop a list of 10 questions about anything - weather, clothing, wildlife, geography, geology, oceanography - related to Antarctica. Each question was worth up to 10 points
There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
Technology geared to the instruction and learning of science concepts, skills, and processes is instrumental to a deeper understanding of science phenomena and content.
Overview
This lesson is intended to introduce students to the concept of scientific exploration and investigation. Students will model the technology used in the Jellyfish in the Bering Sea expedition by using underwater cameras and tow
