Apr. 2008. Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project. [site] 14.56 min
Canadian Encyclopedia: Nuclear Energy - How does nuclear energy work? This article covers introductions to nuclear fusion and fission, radioactivity, the history of nuclear energy in Canada and the potential future of this energy source.
Educapoles.org: Nuclear energy: when atoms explode - "Nuclear energy, which is also called atomic energy, is the form of energy that binds together the constituents of the nucleus of an atom. This energy can be released, mainly in the form of heat, with the disintegration of unstable nuclei (Uranium 235 or Plutonium 239, for example).Uranium is a radioactive...
Nuclear Regulatory Commission: Students Corner - Students can find some great information, including diagrams on this U.S. site. What is nuclear energy? Learn about the types of nuclear reactors, emergency planning, and radioactive waste.
Nuclear Fusion - This brief video illustrates the process of fusion that takes place when an atom of Deuterium collides with an atom of Tritium resulting in the release of energy and the formation of a Helium atom.
Alpha Decay - This video is a brief description Alpha decay. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, and thereby transforms (or 'decays') into an atom with a mass number 4 less and atomic number 2 less.
Gamma Decay - Gamma decay is the radioactive decay of an atomic nucleus that is accompanied by the emission of a beta particle. This brief animation compares the energy released during alpha, beta and gamma particle decay.
Energy Kids: Uranium (Nuclear) - Get the basics about nuclear energy, nuclear power plants, types of nuclear reactors, and getting (producing) uranium, the fuel most widely used for nuclear plants. There are some diagrams and images included.
Radioactive Dating Game - "Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object." [site]
Quantum Wave Interference - "When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they...
Models of the Hydrogen Atom - "How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting photons and alpha particles at the atom. Check how the prediction of the model matches the experimental results." [site]
Atomic Interactions - "Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction." [site]
