50 Awesome Chemistry Videos For The Busy Science Teacher. Though we don’t often recognize it, chemistry defines nearly every element of our everyday lives.
From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week. Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future.
You can get in the spirit of the event by checking out a few (or all) of these amazing chemistry videos online. Amazing Reactions and Experiments Brainiac: Thermite and Liquid Nitrogen: Think thermite reactions are super awesome? Lectures Courses Fun. Browse Interactives.

Physics.org. Big History Project. Threshold 1: The Big Bang. Two scientists with the best equipment available were getting nothing but interference.
Maybe the pigeons were to blame. A flock of pigeons had taken to perching atop the big metal “horn” of their radio antenna near Holmdel, New Jersey, in 1964. Shaped like a giant ear canal 20 feet wide and 50 feet deep, the horn's smooth interior was designed to receive extremely faint radio signals from far off. The two scientists figured the droppings had to be what was interfering with their readings.
They asked workers to clean out the pigeon droppings. Again they pointed the giant ear toward outer space and listened. By now they'd done everything they could think of to eliminate it. Nothing changed. The notion that the Universe might actually be expanding had been proposed at least since the 1920s but it was greeted by a great deal of skepticism from the very start. Einstein didn't agree. “Vos calculs sont corrects, mais votre physique est abominable,” he remarked in French to Lemaître.
Threshold 2: Stars Light Up. Light travels fast.
In one second it races around the Earth seven times. In 1.29 seconds, it reaches the Moon. Threshold 3: New Chemical Elements. Likewise, Aristotle's geocentric view of the Universe had a very long shelf life.
More than 400 years after Aristotle, Claudius Ptolemy was merely refining the great philosopher's cosmological theories, describing a model of a Universe that still showed the Earth at its center and, as one moved outward, a series of concentric spheres containing the Moon, the planets, the Sun, and finally the “sphere of fixed stars.” And centuries after that, Ptolemy's geocentric model and his Almagest – a treatise on the paths of planets and stars – still dominated the thinking at Europe's medieval universities. Where the Higgs. The Large Hadron Collider is located at CERN, the European Organization for Nuclear Research, near Geneva, Switzerland.
This is CERN's Globe of Science and Innovation, which hosts a small museum about particle physics inside. The ATLAS experiment is housed underground nearby. The Higgs boson, the elusive particle that scientists had hoped to find for decades, was detected by two general-purpose experiments at the Large Hadron Collider, as scientists announced in 2012. The Compact Muon Solenoid (CMS) experiment, pictured, is one of them. The ATLAS experiment, seen here in 2011, also detected the Higgs boson, a particle that helps explain why matter has mass. Much of three stories of electronics at CMS are involved in making split-second decisions about what data to keep and what to discard.

Green Chemistry Online Course for Educators Green Chemistry is the science of creating safe, energy efficient and non-toxic products and processes and offers a concrete path towards solving the environmental problems our society faces today.
This course begins with an introduction to the 12 principles of green chemistry and then concentrates on the exploration and creation of green chemistry lesson plan materials. Educational resources that are proven vehicles for bringing green chemistry concepts to high school students will be introduced. These lesson plans are designed to integrate into current curriculum and meet national education standards in science and connecting disciplines.
The materials are designed for high-tech, low-tech and no-tech implementation so that teachers withvarying resources have an avenue for implementation.
