Ozone: Absorbance of UV Light Ozone is produced. Exposure to a shortwave ultraviolet source causes the ozone to cast a shadow against a fluorescent yellow background.
Classifying Matter: A Physical Model Using Paper ClipsBob Blake, Lynn Hogue, and Jerry L. Sarquis By using colored paper clips, students can represent pure substances, mixtures, elements, and compounds and then discuss their similarities and differences. This model is advantageous for the beginning student who would not know enough about the detailed composition of simple materials like milk, brass, sand, and air to classify them properly. Blake, Bob; Hogue, Lynn; Sarquis, Jerry L. J. Chem. Educ.2006, 83, 1317.

Etymology as an Aid to Understanding Chemistry ConceptsNittala S. Sarma Recognition of word roots and the pattern of evolution of scientific terms can be helpful in understanding chemistry concepts (gaining knowledge of new concepts represented by related terms). The meaning and significance of various etymological roots, occurring as prefixes and suffixes in technical terms particularly of organic chemistry, are explained in a unified manner in order to show the connection of various concepts vis vis the terms in currency. The meanings of some special words and many examples are provided. Sarma, Nittala S. J. Chem. Educ.2004, 81, 1437.
