Students calculate the cost of the energy used to operate a common three-bulb light fixture. They then compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs. Students also do a short laboratory activity to visualize why two bulbs, which give off the same amount of light, use different amounts of electrical energy.
In this lesson, students explore several facets of the impact of volcanic eruptions on the atmosphere. Students analyze three types of visual information: a graph of aerosol optical depth v. global temperature, a global map with temperature anomalies, and an ash plume photograph. In the hands-on activity, students use math to determine the rate and estimated time of arrival of an ash plume at an airfield.
This is the seventh of nine lessons in the 'Visualizing and Understanding the Science of Climate Change' website. This lesson addresses climate feedback loops and how these loops help drive and regulate Earth's unique climate system.
In this video segment, two students discuss the greenhouse effect and visit with research scientists at Biosphere 2 in Arizona, who research the effects of global climate change on organisms in a controlled facility. Their current research (as of 2002) focuses on the response to increased quantities of CO2 in a number of different model ecosystems.
This collection of photos from the NASA Climate website features images related to global change. Not all images show change caused directly by climate change and energy use, and descriptive captions indicate causes for change in most of the images.
One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.
This video is narrated by climate scientist Richard Alley. It examines studies US Air Force conducted over 50 years ago on the warming effects of CO2 in the atmosphere and how that could impact missile warfare. The video then focuses on the Franz Josef glacier in New Zealand; the glacier is used to demonstrate glaciers formation, depth of snow fall in the past, and understand atmospheric gases and composition during the last Ice Age. Supplemental resources are available through the website.
This hands-on activity is a kinesthetic game illustrating the dynamics of the carbon cycle. Acting as carbon atoms, students travel from one carbon reservoir to another; at each reservoir they determine, by rolling dice, how long they stay in the reservoir or how likely it is that they will move to another carbon reservoir.
The National Climate Assessment, released in May of 2014, summarizes the impacts of climate change on the United States, touching on many disciplines: earth science, biology, human health, engineering, technology, economics, and policy. Explore the document with a lead NCA author, then learn about related educator resources with Minda Berbeco from the National Center for Science Education. Discover how to bring these resources into classroom lessons, engage students in data collection and analysis, share visualizations and citizen science projects.
Focus this month will be on the Southwest region. Watch for additional regions to be featured in upcoming “Ask US” sessions.
The opportunities and pathways for careers in natural resources and sustainability areas are diverse and the conversation between employers and higher education is only just beginning. This workshop will focus on articulating the breadth of opportunities and identifying the knowledge and skills that are pathways to different types of employment.
