Atoms are very weird. Wrapping your head around exactly how weird, is close to impossible – how can you describe something that is SO removed from the human experience? But then again, they kind of make up everything, so let us try anyways. (04:57)

Where does the weight go when we “lose weight”? What happens when iron rusts? Why are exploding stars able to turn other elements into gold when the alchemists were not? In this session, we will extend and refine the particle model by taking a closer look at the particles—atoms and molecules—and will discover how the law of conservation of matter applies to chemical changes.

Ionic bonding formed when one atom has sufficient strength of attraction to remove ion from the other atom. Covalent bonding occurs when neither atom has sufficient strength to remove the other atom's electron. They would instead share electrons to form stable configurations of electrons. Run time 01:56.

Powers of Ten is an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports viewers to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker- with ten times more magnification every ten seconds. The journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell. (09:01)

This song is about the formation of the two types of chemical bonds: IONIC BONDS and COVALENT BONDS. The tune is to "Dancing Queen" by Abba. Mr. Edmonds uses visuals as he sings. Some of the key words include the following: ionic bonds, covalent bonds, metal, non-metal, electrons, ions, charged atoms, positive, negative, and sodium chloride. This is a great resource to work in conjunction with a lesson/unit on chemical bonds. Students will enjoy this catchy tune. (3:32)

This video describes reaction between tetrahydrofuran and excess HBr. Bromine itself is a very large atom and it spreads the negative charge over that large area which pushes the hydrogen further away from it, making it more vulnerable to attack. Tetrahydrofuran is a very reactive molecule because you are forcing the oxygen into a crowded position with electrons. Those electrons are going to be looking to jump off onto anything they can to go into a lower energy state... Run time 01:44.

Surface science examines how surfaces react with each other at the molecular level. The atoms at the surface are different than those atoms in the center of an object, making the atoms much more reactive than those inside. This program explores a variety of real world applications of this particular property.

All across the immense reaches of time and space, pace, energy is being exchanged, transferred, released, in a great cosmic pinball game we call our universe. How does energy stitch the cosmos together, and how do we fit within it? We now climb the power scales of the universe, from atoms, nearly frozen to stillness, to Earth's largest explosions. From stars, colliding, exploding, to distant realms so strange and violent they challenge our imaginations. Where will we find the most powerful objects in the universe? (25:07)

Magnets have always instilled wonder in both children and adults alike with their seemingly magical properties. In this clip from the 2010 festival, Nobel Prize winning physicist William Phillips demonstrates how scientists utilize magnetic fields to perform otherwise impossible tasks, such as trapping atoms.
