Synthesizing Pigment and Dyeing Cloth

Young scholars practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

In this chemistry worksheet, young scholars write the structures for the compounds listed at the top of the sheet. Then they name the compounds whose structures are illustrated. Students also write the mechanism for the reaction of...

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes....

Synthetic materials increase in popularity every year. Exploring Energy takes on the chemistry behind synthetic materials, including polyester. The resource opens with a video explaining the difference between natural and synthetic...

This site from Frostburg State University answers a dye relevant question and in doing so gives the structural formula of a common dye. It explains how lipstick color lasts, and what chemical produces the red color.

Many (if not most) experiments in the chemistry lab do not get significant results - or the expected results. In this Chemistry Now original video series, we highlight the curiosity, daring, and creativity of the best bench chemists by...

Pupils isolate and identify a dye, which represents a synthetic pesticide, from plants.

High schoolers separate food coloring using liquid chromatography. For this chemistry lesson, students explain the effects of different solvents on the rate of separation.

Students conduct various experiments on chromatography. In this chemistry lesson, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.
