Paramagnetism: Compounds Vials of a number of compounds (NaCl, MnSO4, FeSO4, CoCl2, NiSO4, ZnSO4, K4Fe(CN)6, [Co(NH3)6]Cl3, [Ni(NH3)6]Cl2, and H2O) are hung from a thread. When a magnet is brought near, some of the vials are attracted.

Paramagnetism: Oxidation States of Manganese Manganese(III) oxide, with 4 unpaired electrons per Mn atom, is more strongly attracted to a magnet than is manganese(IV) oxide, with only 3 unpaired electrons per Mn atom. Potassium permanganate, a compound of Mn(VII), has no unpaired electrons and is not attracted to a magnet.
An incomplete concept map is shown below, which set of terms for A, B, C and D would result in a correct map based on the concept of wave mechanics applied to a hydrogen atom?
Guitar Strings as Standing Waves: A DemonstrationMichael Davis This demonstration uses an acoustic guitar to produce three unique harmonic vibrations, each of which is representative of a standing wave and illustrates the concept of quantization. Davis, Michael. J. Chem. Educ.2007, 84, 1287.

Flame Tests: Which Ion Causes the Color?Michael J. Sanger Students determine which of the ions in a series of ten commercially-available ionic compounds are responsible for the observed colors by performing flame test experiments using cotton swabs and a Bunsen burner. Sanger, Michael J. J. Chem. Educ.2004, 81, 1776A.

Student-Centered Learning
Getting Close with the Instructional Scanning Tunneling MicroscopeCarl Steven Rapp This state-of-the-art instrumentation is making it possible for students to actually view atoms in their own classroom. What is truly amazing, however, is that the ISTM can be set up and atomic resolution images obtained in about an hour. Rapp, Carl Steven. J. Chem. Educ.1997, 74, 1087.
