This is a STEM-based lesson that can be taught in class or online. Students will analyze Weddell seal pup growth data, collected by the Growing Up on Ice, B-030, research team. To use this lesson virtually, include the data cards and have students either construct graphs and upload an image of their graph, or construct a graph and share
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
This lesson plan transports students to two field sites outside of Fairbanks, Alaska to investigate the interconnected relationships between climate change and permafrost. Students will use authentic field data from site photographs, soil temperature, and thaw depth measurements to draw inferences. An ESRI StoryMap, faux field journal, and 360 site images are used to engage students in the inquiry
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
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
Data collected from experimental manipulations of ecological processes can help us understand the natural world, and perhaps even help scientists predict how complex systems may change. At CiPEHR, (Carbon in Permafrost Heating Experimental Research) located near Denali National Park, scientists have collected and analyzed seven years of data to learn how increases in soil temperatures influence the carbon
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
When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
