Spectroscopy (SAM) (an 8-page, 1-2 day activity)
This Activity Requires: Test your system to see if it meets the requirements Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page. Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions. |

 | Overview and Learning ObjectivesStudents explore the relationship between an atoms energy levels and its photon emissions. They explore the different ways an atom might be excited. Finally, students compare patterns of spectral emissions in order to identify the atomic constituents of matter. Students will be able to: • Determine that the frequency of a photon is determined by the difference of energy levels. • Add energy and excite atoms. • Analyze photon emissions and identify atoms that emit them. • Determine that atoms can absorb photons of specific frequencies. • Explore emissions spectrum, and identify atoms by their spectra. |

 | Central ConceptsKey Concept: An atom's spectrum is like its fingerprint -- unique to that particular kind of atom. Since every type of atom emits and absorbs only photons of particular frequencies, one can compare patterns of spectral emissions in order to identify the atomic constituents of matter.
