Magnetized Water: Science or Fraud?L. Lahuerta Zamora, G. M. Antón-Fos, P. A. Alemán López, and R. V. Martin Algarra Commercial water magnetizers provide a unique opportunity to help university and secondary students develop appropriate skepticism against extraordinary claims and use testing as the basis for their scientific evaluation. Lahuerta Zamora, L.; Antón-Fos, G. M.; Alemán López, P. A.; Martin Algarra, R. V. J. Chem. Educ.2008, 85, 1416.

Fog Machines, Vapors, and Phase DiagramsEd Vitz This series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles. Vitz, Ed. J. Chem. Educ.2008, 85, 1385.

Stilling Waves with Ordered Molecular MonolayersEd Vitz The amazing ability of a film of oil one molecule thick to dissipate the relatively large energy of water waves can be readily demonstrated, but an explanation of the effect has been elusive until recently. Vitz, Ed. J. Chem. Educ.2008, 85, 1064.

Water #1 (GCMP)David M. Whisnant Water #1: this is a resource in the collection "General Chemistry Multimedia Problems". Isotopes are forms of the same element composed of atoms that have different numbers of neutrons. In this problem we will begin by observing the properties of water containing two isotopes of hydrogen. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
