Three different game types included in this educational game. The base game comes with dozens of colored marbles to represent electrons, protons, neutrons, and photons. Also comes with a large board representing a the generic atomic structure of an element -- its nucleus and first five shell levels.Game 1: Atomic Challenge In this game players use the marbles to simulate electrons, protons, and neutrons as they build and identify different atoms. The objective is to be the first player to use all of your marbles.Game 2: Nuclear Reactions In this more advanced game, players score points by building neutral atoms, stable nuclei, and complete atoms that are both neutral and stable.Game 3: Photons and Lasers This game teaches players how light is emitted and absorbed by atoms. The object of the game is to score points by playing cards and moving electrons up and down energy shell levels. Pump cards build the atom up to excited states, ready for scoring. Laser cards allow players to strategically move electrons down, scoring points, and simulating the emission of light from a real atom.These games would work for grades 4-12 in an educational setting. - BoardGameGeek
