NASA KSNN Why do magnets work?
Magnetism is an invisible force felt within the space around a magnet. This space, called the magnetic field, can either attract (pull) or repel (push away) other magnets and some types of metal
NASA CONNECT Mirror, Mirror on the Universe
In NASA CONNECT Mirror, Mirror on the Universe, students discover how algebra and telescopes are used in space exploration and why optics, which is the study of light, is important in astronomy. Students learn about the Hubble Space Telescope, Hubble Deep Field, and how NASA engineers use algebra in their work.
A blackwater river from sea to source: The White Oak River transect
A "virtual field trip" up the White Oak River in southeastern North Carolina, with discussion of how local ecology changes along the way due to decreasing salinity.
Cape Fear Estuaries: From River to Sea
A "virtual field trip" down the estuaries of the Cape Fear River from zero salinity to the ocean, with discussion of how local ecology changes along the way.
Clays of the Piedmont: Origins, recovery, and use
A "virtual field trip" through the North Carolina Piedmont and thousands of years of history explains the origin of Piedmont clays and how clay is made into pottery. With high-resolution photographs.
Elevations and forest types along the Blue Ridge Parkway
A Carolina Environmental Diversity Explorations "virtual field trip" that explores the great diversity of forests in North Carolina's Blue Ridge Mountains.
Evidence of rising sea level: Coastal erosion and plant community changes
A Carolina Environmental Diversity Explorations "virtual field trip" that examines the causes and effects of changes in sea level, both short-term (as a result of storms) and long-term (as a result of climate change).
Forests and fires: The longleaf pine savanna
This Carolina Environmental Diversity Explorations "virtual field trip" examines the role of fire in maintaining the longleaf pine savanna as well as other rare plant communities found in Camp Lejune, North Carolina.
Hurricanes on sandy shorelines: Lessons for development
A Carolina Environmental Diversity Explorations "virtual field trip" that examines the sand sharing system of sedimentary coastlines and the impact of hurricanes on those coastlines and on human development.
Jocassee Gorges: Temperate rain forests of the Blue Ridge
A Carolina Environmental Diversity Explorations "virtual field trip" that explores the geology and botanical diversity of the Jocassee Gorges region of North Carolina's mountains.
Large sand volume barrier islands: Environmental processes and development risks
This Carolina Environmental Diversity Explorations "virtual field trip" explores the nature and structure of barrier islands with large sand volume, on which built structures are relatively well insulated from hurricane damage.
Lonely mountains: The monadnocks of the inner Piedmont
This Carolina Environmental Diversity Explorations "virtual field trip" explores the geology of North Carolina's monadnocks, mountains that rise individually above the surrounding topography.
Natural and human impacts on the northern Outer Banks
This Carolina Environmental Diversity Explorations "virtual field trip" examines how coastal process continuously alter the structure of the Outer Banks, and how humans have adapted to and resisted these changes.
Small sand volume barrier islands: Environmental processes and development risks
This Carolina Environmental Diversity Explorations "virtual field trip" explores the nature and structure of barrier islands with small sand volume — only a few small dunes and no sandy ridges between the beach and the salt marsh. Built structures on these islands are highly susceptible to damage from hurricanes. This trip provides high-resolution photographs of two such islands, Masonboro (which has not been developed) and Topsail (which has been developed). Its companion field trip, Large Sa
Wetlands of the coastal plains
This Carolina Environmental Diversity Explorations "virtual field trip" explores the various wetlands of North Carolina's coastal plain, including the longleaf pine savanna, sandhill scrub, pocosin, pond pine woodland, coastal plain bottomland forest, tidal freshwater marsh, cypress gum swamp, and salt marsh. In each type of wetland, you'll learn about the various plant communities and their adaptations to their environment. You'll also learn how wetlands are formed and why North Carolina has so
Viewing the Periodic Table of the Elements with X-rays
X-rays and x-ray fluorescence are not new subjects to the field of physics. Wilhelm Röntgen discovered x-rays in 1895, and in 1901 he was awarded the very first Nobel Prize in physics for this discovery. Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum. He was awarded a Nobel Prize in physics for this discovery in 1917. Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete
Action Potential Experiments
Action Potential Experiments is a demonstration/simulation laboratory for neurophysiology based on the 'sodium theory' as originally formulated and tested by A. L. Hodgkin and his colleagues. The application includes simulations of the original experiments of Hodgkins and his colleagues, and of the classic voltage clamp and patch clamp experiments and an animated illustration of the 'sodium theory' explanation of Nernst potentials for potassium and sodium ions. The student can perform simple ion
Essential Physics I
Essential Physics 1, is an intensive introduction to classical and special relativity, Newtonian dynamics and gravitation, Einsteinian dynamics and gravitation, and wave motion. Mathematical methods are discussed, as needed; they include: elements of differential geometry, linear operators and matrices, ordinary differential equations, calculus of variations, orthogonal functions and Fourier series, and non-linear equations for chaotic systems. The contents of this book can be taught in one seme
Social Psychology - Spring 2008
Social Psychology - Spring 2007. The course will begin with a historical introduction to social psychology, focusing on the intellectual contribution of Kurt Lewin and the integration of evolutionary and cultural approaches to human nature. The course will then focus on the major topics of social psychology (group dynamics, social influence, attitudes and attitude change, social perception) as well as more specific areas of research (altruism, emotion, justice) and recent developments in the fie
Geography: Natural Resources and Population Spring 2008
Natural Resources and Population – Spring 2008. Ever since publication of Thomas Malthus’s Essay on the Principle of Population in 1798, the English-speaking world has equated population growth with apocalypse, even though Malthus’s theory was debunked well before his own demise in 1834. This course begins from the proposition that human-environment relations are always social relations: how natural resources are produced, distributed, valued, consumed, conserved and degraded are historica
