| Abstract |
|
In this classroom activity, students explore the chemistry of polar and nonpolar substances and surfactants while marbling paper with consumer products. Shaving cream, a soap lather, is used as a base for supporting food color marbling patterns. Once the shaving cream is tinted, the excitement and marbling action continue as a drop of water on tinted shaving cream makes a clean white surface. As beautiful colored patterns are created, students refine their understanding of the hydrophilic and hydrophobic nature of the different marbling materials. Students compare diffusion of a dye in different materials, observe the wetting action of soap solutions and surfactants, and investigate a colloid.

 Caution! | | Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations. |

| Chemistry Teacher Connection |
|
The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
|
| C&EN CLICs |
|
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
