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
Exploration of the Antarctic continent did not occur until the late 1800’s, and the South Pole was first reached on December 14, 1911. Courage, planning, and technology have been the main components of Antarctic exploration from the earliest days. This classroom activity is designed to highlight the historical elements of the past 100 years of exploration in Antarctica and
Antarctica is the coldest, driest place on Earth with a fairly limited number of native species which have adapted to these extreme conditions over millions of years. As a result, it's not very likely that a non-native species would survive there . . . right? Actually ever since exploration and exploitation of the Antarctic region began in the 1800's
I, Elizabeth Eubanks PolarTREC teacher 2008 – Arctic Tundra Dynamics created this lesson to introduce my students to utilizing technology to document and share what they know, want to know and have learned about polar studies and environments.
Objective
The objective of this lesson is for students to utilize recording devices (audio with or without video) and
Elizabeth Eubanks PolarTREC teacher 2008 – Arctic Tundra Dynamics created this lesson to introduce her students to a wide variety of polar scientists and their research. Students will use the PolarTREC and other websites to learn about the various research projects that are going on at the poles. After students have tracked 10 polar scientists they are then
