The PCR Song
"Scientists for Better PCR" produced this Bio-Rad Music video that is filmed in the style of a celebrity benefit. The music video is a commercial for a BioRad thermocycler, which is essentially a DNA copying machine. During the song, there are jokes about the particulars of reproducing the genetic material as well as terms students may need to become familiar. The value of the video is that the terms used provide insights into the uses of DNA and can provide students with an idea of how th
July 4 Fireworks: Behind the Scenes in the Nation's Capital
This four minute video would be good to show students before they watch the July 4th celebration from Washington DC. It explains where the fireworks come from, the planning, and shows how the shells are made, how large they are and how they are fired. (4:00}
Science Bulletins: The Moon's Fragile Oasis
A NASA lunar probe reveals that the Moon stores more ice at its poles than previously thought.
Science Bulletins: Super- Star of the Universe
A local star is the most massive ever detected.
Science Bulletins: In Hot Pursuit of Asteroids
Asteroids, the rocky remnants left over from the formation of planets in the Solar System, offer scientists a window into the dynamics of this early period. Scientists from around the world are currently exploring asteroids with a small fleet of unmanned spacecraft designed to collect images, samples, and other data.
Science Bulletins: Graphite Found in Moon Rocks
Scientists have discovered the first evidence of the mineral graphite on the Moon, detected in a rock collected in 1972 by astronauts on Apollo 17, the last manned mission to the Moon.
Science Bulletins: Cosmic Collisions Fuel Black Holes
Swift is a NASA satellite designed to spot gamma-ray bursts, the most powerful explosions in the Universe. They are named for the extremely energetic gamma rays they emit. Swift can also detect high-energy, or "hard" X-rays, which have nearly the energy of gamma rays. Swift's ongoing survey of hard X-rays in space is revealing details about what kinds of dynamic cosmic activity can release such high-energy wavelengths of light.
Science Bulletins: Star Bolts from Crowded Nebula
No star-forming region in our local Universe is as vigorous as 30 Doradus, also called the Tarantula Nebula. Now astronomers have used NASA's Hubble Space Telescope and ESO's 2.2-meter telescope at La Silla, Chile, to spot an outlier-a star destined to exit the nebula because of gravitational interactions among its throng of massive stars. This is the first direct observation of a stellar runaway in a dense, massive cluster.
Science Bulletins: New Evidence of Water on Asteroids
For the first time, researchers have detected water on an asteroid. Two research teams independently determined that the 24 Themis asteroid, which orbits between Mars and Jupiter, is completely covered in a thin layer of frost. The discovery indicates that comets and asteroids may be more similar than previously thought. Comets are traditionally defined as small lumps of rock and ice that form vapor tails when they venture close to the Sun. Asteroids are usually characterized as large dry rocks.
Science Bulletins: New Solar Satellite Delivers First Images
The Solar Dynamics Observatory (SDO) has been hailed as the "Hubble Space Telescope for heliophysics"—a state-of-the-art spacecraft that will observe our nearest star with unprecedented detail. Its first images reveal two solar events that burst into view just after SDO's telescope array, called the Atmospheric Image Assembly (AIA), readied for operations on March 30, 2010. In this Science Bulletins snapshot, watch a prominence and a solar flare like you've never seen them before, and learn ho
Vietnam Revolution 1945 Part 3
Fired by the dream of independence for his country, Ho Chi Minh spent a lifetime trying to find the right combination of forces necessary to get the French out of Vietnam. This is a great resource to use in conjunction with non-fiction texts and/or lessons on the Vietnam War. (4:25)
God Bless Cowboys on Vimeo
This is a digital postcard of a ghost town in Calico, California. This short video consists of footage of a town that looks like how old western towns looked during the Wild West era. This would be good to give students a visual of what these small towns looked like. (01:18)
Science Bulletins: Australia's Coral Growth Slows
Corals, like clams, lobster, and sea urchins, are marine calcifiers—they incorporate dissolved minerals from seawater to grow their hard parts. Calcifiers are considered at risk from our increased introduction of carbon dioxide into the atmosphere from the burning of fossil fuels. Carbon dioxide in the air increases the temperature of the ocean by ramping up the greenhouse effect, and the absorption of carbon dioxide into the ocean changes its chemistry so that minerals are less available for

Determine Coordinates of Transformations-Shooting Pool
Examine coordinates of images that have been rotated, reflected, translated or dilated. Connect the idea of transformations on a coordinate grid to the angles of shots in a game of pool. Answer questions and solve problems to advance through this lesson.
Science Nation - Orangutan Copycats
By: nsf How smart are copy cats? Maybe it depends on your species You know the saying "monkey see, monkey do?" How about "orangutan see, orangutan do?" If that holds true, the small orangutan peering over his mother's shoulder in an enclosure at Zoo Atlanta should learn how to get a tasty treat just by watching how she gets one.

Science Nation - Spray-On Solar
By: nsf Have you seen those big, bulky, breakable photovoltaic cells that now collect the sun's rays? Well, what if solar energy could be harnessed using tiny collectors that could be spray painted on a roof, a wall or even a window? Find out more on this episode of Science Nation.

Allied Invasion of Italy
In September, 1943, Italy surrendered unconditionally to the Allies, while German forces quickly occupied north and central Italy. Aided by the Germans, Mussolini escaped from prison and established a puppet republic in northern Italy. In this video clip, learn more about the invasion of Italy. (3:37)
