Chemists add color to our lives by the synthesis of paints and dyes. This activity investigates paints and dyes and the chemical reactions involved in their synthesis and use. Students will learn the qualities of some common dyes and paints; learn the chemical reactions involved in the production of dyes and paints, and learn several methods of dyeing textiles. By experiment, students will separate white light into its major colors and separate black ink into its component colors; dye cotton with indigo blue and dye wool with a vegetable dye; and make four paint pigments and prepare an oil-based paint. A 58-page teacher's guide (with answers) and a reproducible 37-page student lab manual are provided. Requires about six class periods to complete.
