Nuclear Chemistry – discussion of radiation, nuclear reactions, and half-life, with animated demonstrations of fission, fusion, and chain reactions.
(Main Idea: Radioactive decay leads to more stable nucleons; Half-life is the time for one half of an amount of radioactive nuclei to decay.)
ABC’s of Nuclear Science – introduction to nuclear science, including structure, radioactivity, decay, and more.
(Main Idea: An atom’s mass is less than the masses of its parts; Nuclear reactions affect the nucleus of an atom.)
Atom Builder – Interactive game in which you add protons, neutrons, and electrons to a hydrogen atom to build a carbon atom. Make sure to keep the charges balanced!
(Main Idea: An atom’s mass is less than the masses of its parts.)
Natural Radioactive Series – animated demonstration of your choice of radioactive decay series, showing the parent material and its change through decay over time.
(Main Idea: Radioactive decay leads to more stable nucleons.)
Radiocarbon dating feature, with discussion of carbon-12 and carbon-14 as they occur in nature, and how scientists work with these forms of carbon to carry out radiocarbon dating in the laboratory.
(Main Idea: Radioactivity has surprising applications.)
Nuclear Fission and Nuclear Fusion
Nuclear Fission – interactive activity in which you bombard uranium with neutrons and see the effects, including chain reactions, and take look inside a nuclear reactor!
(Main Idea: In fission, atoms split into nearly equal parts.)
Nuclear Fission and Nuclear Fusion – tutorial on nuclear fission and nuclear fusion.
(Main Idea: In fission, atoms split into nearly equal parts; Nuclei combine in nuclear fusion.)
