The Dry Valleys Ecosystem project (a Long Term Ecological Research program - LTER) has been a continuous line of research since the inception of the McMurdo Dry Valley LTER since 1992. This project seeks to test hypotheses regarding the response of Antarctic biotic communities to changes in climatic conditions over time. I participated in the 30th
Teacher Bill Henske describes the science and fieldwork behind the Dry Valleys Ecosystem Study from McMurdo Field Station in Antarctica. This presentation took place on 24 January 2023.
Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
After spending 5 weeks in the Arctic learning about tundra vegetation and phenology, Alejandra Martinez wanted to have her students observe the growth of plants in their school. In this lesson, students will grow plants in multiple locations and track their growth to compare their phenology.
Objectives
Students will learn what phenology is and make observations about plant growth
South Texas is pretty far removed from the Arctic. When I mention climate change in my classroom, my students think of emaciated polar bears roaming the Arctic Ocean for a few minutes and then carry on with their day. I needed to find a way to connect what was happening in the Arctic to
Educator Ale Martinez and the team researching Phenology and Vegetation in the Warming Arctic live from Toolik Field Station in Alaska. This event was broadcasted on 25 June 2019.
Florida International University (FIU) Preeminent Program research team hunts for the drivers of global climate change in the Arctic. Video produced by Florida International University, May 2019.
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.
Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
