Contour Basics is an exercise designed to introduce students to contour plots. The Contour Activity is a great on-line resource that starts slowly and increases in difficulty. It teaches students basic techniques for generating contours, introduces students to the subtleties of generating contour plots with sparse data, provides many opportunities for students to assess their own progress and understanding and has complete on-line drawing capabilities. The exercise is geared toward atmospheric a
A German Way of War? Atrocities and Military Dictatorship
Description not set
This site from SERC describes ConcepTests, which are conceptual multiple-choice questions that were originally designed by Eric Mazur at Harvard University for students in large physics classes. ConcepTests are generally short, and as they are multiple-choice, they are useful for immediate quantitative assessment of student understanding. It may be useful to the instructor to know how many correct responses there are to a question both before and after peer instruction to better gauge student un
Climate Monitoring and Diagnostic Laboratory: Carbon Cycle Greenhouse Gases
The National Oceanic and Atmospheric Administration Climate Monitoring and Diagnostic Laboratory Carbon Cycle Greenhouse Gases group makes ongoing discrete measurements from land and sea surface sites and aircraft, and continuous measurements from baseline observatories and tall towers. These measurements document the spatial and temporal distributions of carbon-cycle gases and provide essential constraints to our understanding of the global carbon cycle. This website is an interactive atmospher
Climate Impact of Quadrupling Atmospheric CO2: An overview of GFDL Climate Model Results
In this report, the Global Fluid Dynamics Laboratory Climate Research Group examines the possible climate impacts of quadrupling atmospheric CO2. Several impacts are discussed, surface air temperature warming, sea level rise, thermohaline circulation changes, mid-latitude summer drying, heat index and temperature increases and possible changes in tropical storms and El Nino. This site provides a nice written overview and images regarding changes in climate and oceans due to increased CO2.
Calibrated Peer Review: Petroleum Geology of the Persian Gulf Region
In this assignment, students explore the origin and distribution of oil and gas in a region of global significance. Also included are the geologic history and the socio-political and environmental issues associated with hydrocarbon exploration and production. Students then walk through an online case study and write an essay addressing important points that they have learned. The Calibrated Peer Review interface is then used to give feedback on the essays. On this Starting Point page, users can
Training Educators to Design and Develop ODL Materials
Welcome to this facilitator’s guide. It contains exciting materials for conducting a workshop to train educators to develop Open and Distance Learning (ODL) resources. As you navigate through this document you will find materials needed for planning and conducting sessions for training educators in the development of ODL learning resources. These materials have been designed so that they can be used for professional development as well as for personal knowledge. This facilitator’s guide is
The Earth and Beyond: Distinguishing the most important groups of materials
Learners respond confidently to their desire to learn about natural phenomena; they investigate relationships and solve problems within the context of science, technology and the environment. In this activity, learners will show an understanding of the interrelationships between science and technology, society and the environment.
This activity is designed to help students gain a deeper understanding of cosmology. Students develop authentic models and gather evidence supporting the Big Bang theory. This lesson uses observation, interactive media, and scientific models.
Who Can Live Here? Life in Extreme Environments
Astrobiology in the Classroom leads students in the exploration of the limits of life on Earth to extend their beliefs about life to include its possibility on other worlds. In this four-part activity, students first explore the environments of several mammals and birds to better understand how living things and their environments interact and depend on each other. In the second part, students match bacterial types with their more extreme environments. Students discover that an environment's tem
EO Global Warming
Earth Expeditions: Global Warming has been designed to provide students with an interactive multimedia environment where they can learn about the causes and possible effects of the rise in concentrations of carbon dioxide in the atmosphere for more than a century. How will Earth’s environment be affected if this rise continues over the next century? The multimedia package provides background information about radiation from the Sun and Earth, the Earth’s energy balance, and the greenhouse ef
Earth Explorers Series
Who Are NASA's Earth Explorers? The elementary school student questioning if El Nino occurs anywhere besides the Pacific Ocean... The researcher investigating connections between Arctic ozone depletion and global climate change... The consumer comparing hydrocarbon versus hydrogen-powered cars... And the business person projecting future needs for harvest, delivery, and storage of crops... All of these people are Earth Explorers -- they are all connected by their curiosity about Earth system pro
Amazing Space consists of web-based educational presentations for young children about space, which were developed at the Space Telescope Science and Technology Institute. Teachers teamed up with scientists and engineers from the institute and staff members from the Office of Public Outreach to develop interactive lessons. All lessons include spectacular photographs taken by the Hubble Space Telescope and many high quality graphics, videos, and animation designed to enhance student understanding
The HPLC Doctor
This site provides HPLC troubleshooting tips. It covers common separation problems such as peak fronting or tailing and split peaks and suggests solutions. This site will be most useful for students and practitioners who already have some background knowledge of separation theory. It will be especially helpful for laboratory or research students who are developing a new separation method or are encountering problems with their chromatographic experiments.
This Web site provides comprehensive information, selected by medical doctors, about the common cold. The goal is to provide a framework for critical thinking which will allow informed decisions about medical care for the common cold. The section entitled Understanding Colds gives a detailed overview of how the cold virus invades the human body and how cold symptoms are caused. Information about preventing colds, and some of the complications that can occur are also included. The Special Feature
Middle School Portal: Math and Science Pathways (MSP2)
Now an annual event, National Engineers Week was founded by the National Society of Professional Engineers in 1951. In 1988, the National Engineers Week consortium expanded and now includes more than 100 engineering, scientific, and education societies and major corporations dedicated to enhancing the public understanding of the engineering profession and to promoting pre-college interest in math, science, and engineering as a career option. From this website, visitors can read suggestions for w
Introductory Tutorial to Mass Spectrometry
An introduction to GC-MS for beginning students in analytical or organic chemistry lab.
