The Inorganic Chemistry of Painting— Guided-Inquiry Kit
By: The Flinn Staff
Challenge your students to design the best paint by applying their knowledge of chemistry and experimental design. This lab begins with the synthesis of an inorganic mineral, malachite, from the reaction of copper(II) sulfate with sodium bicarbonate. Color changes, gas evolu- tion and formation are all products of the reaction. Once made the malachite is mixed with a binder like linseed oil, acacia powder or egg yolk that makes it adhere to the surface to be painted.
Students must combine all reactants in the appropriate proportions, based on stoichiometric calculations and experimentation, to produce the best possible paint, one that pops with color and has strong adherence to paper! This lab combines art and chemistry in a way that will develop your students’ scientific reasoning skills. Includes reproducible student hand-outs, Teacher Notes, and all necessary chemicals.
Complete for 30 students working in pairs.
Exploring Chemical Reactions with
Food Dyes—Student Laboratory Kit
By: The Flinn Staff
Dyes color our world and are found in everything from clothing to food. Yet only seven dyes are used to make all of the artificial colors seen in food made in the United States. Food processing is a rigorous undertaking—explore how these dyes may change color under differ- ent chemical conditions. Students test four out of the seven FD&C food dyes with a series of reactants, including acidic and basic solutions, simulated hard water and oxidizing and reducing agents to determine whether a chemical reaction takes place.
Complete for 30 students working in pairs. Fifteen reusable 24-well reaction plates are recommended and available separately.

Student Laboratory Kit
By: The Flinn Staff
Start with copper—end with copper! Students perform a series of chemical reactions to convert copper metal to its nitrate, hydroxide, oxide, chloride, phosphate, sulfate, and finally...back to copper metal. Students practice many standard laboratory techniques such as filtering, decanting, precipitating, and neutralizing as they perform this amazing chemical feat. For each reaction in the cycle, students write a balanced chemical equation, note physical states of products, learn reaction types, and calculate percent yield.
Complete for 30 students working in pairs. Perform this experiment in a fume hood or well-ventilated lab. Entire lab may take 3–5 labora- tory periods.
