‘Gold, sand, and string’ considers elements of the Periodic Table from which every material we use is built. It focuses on three materials—gold, sand, and string—that represent the metallic, inorganic, and organic resources on which we draw. The atomic structure of gold, silver, iron, and copper are described along with the important alloys that can be created from them: bronze, brass, and steel. Quartz (silica) and calcite are also important minerals used in glassmaking and cement manufacture, respectively. Cellulose, a polymer made up of a sugar-molecule chain, is the most abundant material in the biosphere. It is at the heart of cotton and the commodity materials of wood and paper.

Chapter 3 focuses on the concept of atoms, which dates back to the ancient Greek philosopher Leucippus, who claimed that everything consisted of them. This view began to be accepted among scientists when John Dalton championed it in the 1800s, although he was wrong in his atomic structure of molecules. That was corrected not long after by Jöns Berzelius. From then on the reality of atoms, and whether those of chemistry were the same as those of physics was a matter of debate. The theory of statistical mechanics, developed in the second half of the nineteenth century, helped establish their reality for most physicists, while many chemists were won over later, in part by the periodic table developed by the Russian Dimitri Mendeleev. Nearly every scientist was finally convinced by the explanation of Brownian motion by Albert Einstein and Marian Smoluchowski, whose formulas were verified by Jean Perrin in 1909.

In this work we present and analysis of the influence of workshop activities performed in our city regarding the dissemination of crystallographic science in all educational levels. The organized workshops in honor of the IYCr are aimed to introduce crystallography to elementary and high schools teachers. The main goal is to improve teachers' knowledge in crystal formation and its techniques. This will allow teachers to elaborate laboratory projects that include crystallography principles according to their own students' level and to encourage the participation in the national and international crystal growing competition. Topics: 1. Introduction to crystallography 2. Atomic structure, chemical bonds and periodic table 3. Types of crystalline solids: metallic, ionic and covalent 4. Crystalline systems 5. Introduction to structure determination using X-ray diffraction 6. Crystal growing
