[ILLUSTRATION OMITTED] Recycling metals is a major business in the United States. Copper, iron, aluminum, and other metals get recycled in various ways. Planned garbage pick-ups, random hauls by individuals to a scrap metal facility, and various organizational recycling of scrap metal (e.g., aluminum can)/clean-up drives are some of the ways metals get reused. This article describes a series of activities that incorporate multiple subjects, which focus on real-world experiences. Science, Technology, Engineering, and Mathematics (STEM) is an emphasis area, as students are actively involved in understanding some of the costs behind the processes of recycling various metal products. A final classroom-tested activity based on shipping Lincoln pennies for copper reclamation is described in detail. Activity 1: Building background knowledge Begin the activity by asking students a series of questions to determine their background knowledge concerning metallic elements. Some sample questions asked in the past are: * What is a metallic element? * What are examples of metallic elements? * How do you determine a metallic element's value? * Where are metallic elements found? * What are some by-products of metallic elements? (You may have to give students a specific example [e.g, an aluminum bat is a by-product of the metallic element aluminum] to gain an understanding of the word by-product. A more difficult concept would be by-products made from metallic alloys [e.g., a bronze statue].) Assign groups of three students to research background information on metallic elements such as aluminum, nickel, silver, gold, mercury, copper, zinc, tin, lead, and iron and do a presentation on them. To help lead discussions in Activity 3, one group should research copper and another group should research aluminum. Specific roles that should be matched with student interests are: * Lead computer researcher: a student who excels at using technology to research a topic. All group members should assist. * Lead writer/compiler/media developer: a student who is good at synthesizing information and putting it in a visually appealing format. All group members should assist. * Lead presenter: a student who tends to be gregarious, outgoing, and extroverted in nature. All group members should assist. Some of the information students should investigate and questions they should answer are: 1. What is the chemical symbol for the metallic element? 2. What are chemical and physical properties of your assigned metallic element? (e.g., melting point, state at room temperature, density, etc.). 3. What is the current price of the element on the commodities market (see Resources)? Students have noticed that these prices fluctuate and sometimes are priced based on unusual units of measurement (e.g., Troy ounces). 4. What are three common uses for the metallic element by itself? This is a tricky question in that most metal products are not a 100% pure Most students determine that a metallic element is mixed to form an alloy of some type. 5. What are three common uses for the metals when combined with other elements to form compounds? The word compound may be new for some students. Provide a few examples (e.g., all-metal compounds such as bronze, which is made of tin and copper, and carbon steel, which is made of iron and carbon, or other types of compounds, such as silver nitrate, which are made of the metal silver and a nonmetal nitrate (combination of nitrogen/oxygen), etc. 6. Where is the metallic element mined? Which state or country is the greatest producer of the metallic element? 7. Provide a timeline-based history of the metallic element. There should be a minimum of four important moments in history regarding the metallic element. 8. Develop a presentation using presentational software (e. …
