This visualization shows static and animated images of changes in Arctic sea ice 1984-2016.
This article describes several traditional Inuit games and provides background information and resources for incorporating them into a lesson or unit on Inuit culture.
In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.
This issue of the free online magazine, Beyond Penguins and Polar Bears, explores the amazing birds that live in or migrate to the polar regions. The issue was co-produced with the Cornell Lab of Ornithology. In addition to content knowledge articles and lesson plans, the issue includes information about bird-themed citizen science programs from the Cornell Lab of Ornithology.
This article assembles free resources from the Arctic and Antarctic Birds issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.
This informational text introduces students to similarities and differences in the North and South Poles. The text is written at a grade one through two reading level. This is a PDF containing the informational text and a glossary.

In this video we show you how to connect Bit-zee's Arduino micro-controller to his frame. Created by Karl Wendt.
Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty County of the maintenance and lifespan concerns associated with its dam.
In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.
In this lesson, students investigate whether other parts of the world are changing and getting hotter just like Colorado.
The year is 2032 and your class has successfully achieved a manned mission to Mars! After several explorations of the Red Planet, one question is still being debated: "Is there life on Mars?" The class is challenged with the task of establishing criteria to help look for signs of life. Student explorers conduct a scientific experiment in which they evaluate three "Martian" soil samples and determine if any contain life.
This lesson explores the similarities between how a human being moves/walks and how a robot moves. This allows students to see the human body as a system, i.e., from the perspective of an engineer. It shows how movement results from (i) decision making, i.e., deciding to walk and move, and (ii) implementing the decision by conveying the decision to the muscle (human) or motor (robot).
In this lesson children will investigate 6 major pollutants in our world and how they can be eliminated or limited. This lesson is a continuation of the other Are We Our Own Worst Enemy ? lesson plans. It can stand on its own but if you haven't taught the others you may want to show the World Population Over Time video before starting this lesson. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
This two week assignment asks students to interpret and analyze the 1974 Arecibo Message sent by Drake and Sagan. Week 1 introduces the concepts behind the construction of the message and engages with a critical analysis of the architecture and the contents of the message. Week 2 asks students to develop software in a Jupyter Notebook (available for free from the Anaconda Python Distribution) to interpret messages that were similar to those produced by Drake and Sagan.
As an introduction to bioengineering, student teams are given the engineering challenge to design and build prototype artificial limbs using a simple syringe system and limited resources. As part of a NASA lunar mission scenario, they determine which substance, water (liquid) or air (gas), makes the appendages more efficient.
The bag itself was immediately recognizable in that the ALSJ long has had a page devoted to what the astronauts referred to as a McDivitt Purse.
