Students investigate 8 household white powders and classify them based on their physical and chemical properties. Using their findings, students then identify an unknown powder obtained from a crime scene to determine the suspect's guilt or innocence. Students gain experience in the identification of chemical and physical changes, careful organization of data, and writing chemical reactions.…
Students use household materials and a conductivity probe to explore factors that affect the conductivity of electrolytic solutions. Students gain experience in molarity and dilution calculations, solution preparation, nomenclature, statistical analysis, and graphical presentation of data. This hands-on activity is flexible and can be modified to accommodate both high school and undergraduate courses. Students can safely…
Hands-on learning in a remote laboratory environment.
This Journal of Chemical Education Article by Deon T. Miles and William G. Wells of the Department of Chemistry, Sewanee: The University of the South describes a homemade kit with at home, hands on laboratory experiments in spectroscopy and chromatography. The paper and supporting information describe both hands on…
This experiment was designed as an at-home lab experiment where students use a portable fluorescence spectrometer to quantitate riboflavin in energy drinks. This experiment can be adapted for a range of educational levels, depending on the background information given. This work is adapted from the work of others (see below).
The attached file provides general instructions,…
