The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen. Students select a common and easily identifiable bird species in their region and observe when the bird species first arrives. Students use binoculars or telescopes to scan a study site and count how many they see. They continue to observe every other day until few or none of the selected species can be seen.

This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.

This animation shows the Arctic sea ice September (minimum) extents from 1979-2016. Accessible from http://nsidc.org/cryosphere/sotc/sea_ice.html

This visualization shows static and animated images of changes in Arctic sea ice 1984-2016.

This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.

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.

Students will complete this survey that determines their personal and household contributions to atmospheric Carbon dioxide by using information about their previous year's consumption. They will understand that Carbon dioxide is a greenhouse gas produced by the combustion of fossil fuels, and that its production can be minimized by taking personal steps to conserve.

This unit, in which students prepare to observe arthropods in their field site's different microhabitats, helps set the stage for a discussion on the ramifications of habitat loss. It's designed to be completed in four or more sessions and has comprehensive curriculum materials for teachers, including activity tips and an overview of the microhabitats in a temperate forest. The unit is designed to answer the following two target questions. What microhabitats exist at our site? Do different arthropods occur in different microhabitats?

Students improve their written observations by using their 5 senses and words that are relatable to others. Create statements that are based on observable facts in the natural world.

In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.

This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

The impact of natural disasters is made vivid in this video segment adapted from NOVA. A small town in Iceland, prepared for recurrent avalanches, is devastated when one takes a new and damaging path.

This lesson uses centers to reinforce the five senses incorporating backyard science in the wonderful world of nature.

In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

In the open ocean around the Bahamas, pods of wild Spotted Dolphins frolic in the sunshine. Sometimes, they get bored and approach boats. In this educational video, Jonathan joins dolphin expert Wayne Scott Smith to learn how dolphins interact with each other. Jonathan learns how to play the Bandana Game, a game of -keep away- that the dolphins invented and like to play with Scott. Please see the accompanying study guide for educational objectives and discussion points.

This video segment from the Nevada Department of Wildlife looks at various species of bats and how they impact the environment.

This Nature video segment focuses on the four foods most important to the grizzly bears' survival, and it describes the threats to the supply of each of them.
