Description
The meaning of its name is unknown, although its origins are Anglo-Saxon. Gold is a soft, shiny, yellow metal, and has been used and highly valued by humans for 4,500 years. It is the most malleable and ductile of any element and it can be beaten into a metallic film a few microns thick. Gold is also a good conductor of heat and electricity. It must be hardened with another metal to make it useful; pure gold is too soft for most uses. It is used as money and is the standard for monetary systems in many countries. It is also used in jewelry, dental work, electrical contacts and wires, photography, and as a colored coating for special types of glass. Gold is good at reflecting heat, and it is often used as a plating on spacecraft to keep them cool. A radioactive isotope of gold is used to treat cancer. A compound of gold is used to treat rheumatoid arthritis. The symbol for gold, Au, comes from the Latin word for gold, “aurum.”

New Monumental Minerals Poster

The new 24” x 36” two-sided MEC Monumental Minerals poster showcases monuments from across the United States and the mined rocks, minerals and metals used to create them. Highlighting well-known monuments points out the importance of mined materials to the public and makes a great tie-in to the country’s 250th anniversary celebration in 2026. The multidisciplinary content of this poster includes science, social studies, history, geography, and art.
The front of the poster has images of diverse U.S. monuments and describes the materials mined and processed to make the monuments.
The reverse side of the poster has several activities that teachers, parents, and grandparents can do with students. “Build Your Own Monument” and the “Building Stones: Your Local Gateway to STEM” activities encourage students to consider what monuments mean and to research types of building stones used in their region.
