Outreach and Education Division

    The EDUCATION AND OUTREACH DIVISION supports chemistry education at all levels, including K-12, college, and adult/continuing education. It maintains liaisons to the Chicago Public Schools and the American Association of Chemistry Teachers (AACT). The Division engages the general public in chemistry-related educational activities, participates in ACS activities at the annual Illinois State Fair, and publicizes all events and news-related content. The division oversees the annual Project SEED program for the Section as well as the Project SEED scholarships. The Division also assists public officials and other community bodies concerning chemistry-related matters. The Education and Outreach Division includes the Education, Outreach, Project SEED, and Public Affairs Committees.

    The EDUCATION COMMITTEE provides chemistry-related educational programs and information to learners of all ages and actively engages with educators at the pre-K-12 and college levels. Subcommittees include:

    • AACT Liaison
    • College Education Subcommittee
    • Continuing Education Subcommittee
    • Chicago School Board Liaison
    • K - 12 Education Subcommittee


    The PUBLIC AFFAIRS COMMITTEE ensures that section members and public officials and bodies are informed of matters where the knowledge and practice of chemistry is of substantial public importance. These matters can include government issues, environmental issues and the social responsibility of chemists. The Public Affairs Committee gives the Public Affairs Award biennially.

    The OUTREACH COMMITTEE engages the general public, educators and children in chemistry-related educational activities and participates in many different types of events around the greater Chicago area.   Subcommittees include:

    • Community Activities Subcommittee
    • Illinois State Fair Subcommittee


    PROJECT SEED COMMITTEE identifies interested low-income and/or minority high school junior and senior students who are interested in participating in a paid summer research experience with  a college or university faculty member.  It supports financial and logistical concerns for the student/ faculty relationships and communicating  relevant program information to the national ACS organization.  The committee is also responsible for distributing Project SEED awards to support the internships. 

    Pencil Chemistry

    Kids, did you ever wonder why everyone calls that stuff in pencils "lead" when it isn't really lead at all? Instead, it is a nontoxic mixture of graphite and clay (more on that later). Way back in the days of the Roman Empire, actual lead rods were used to write on papyrus. But more recently, in the 1500's, a graphite mine was discovered and graphite was found to leave darker marks on paper. At the time, everyone thought that graphite was a type of lead. They called it black lead or plumbago. The chemical symbol for lead is Pb, which stands for the Latin word plumbum (check for a complete history of lead).

    Please note:  All chemicals and experiments can entail an element of risk, and no experiments should be performed without proper adult supervision.

    By nearly 1800, chemists finally proved that black lead was really a form of carbon. Carbon exists in the elemental form as either graphite or diamond (or, as we have recently discovered, nanotubes and buckyballs). Because graphite is so soft, it needs a holder to support the skinny sticks used for writing. Low quality graphites need to be further strengthened by mixing with clay and water (see the Nov. 1996 ChemShorts to learn more about clays). A slurry of these three ingredients is crushed, mixed for three days, extruded into the thin rods, and then heated to dry out the water. The ratio of clay to graphite affects the hardness of the "lead": the more clay, the harder the pencil lead. This means that less graphite is present to transfer to the paper, resulting in lighter lines. The higher the number, from 1 to 4, the harder the lead. Get a sampling of pencils of various hardnesses and check out their writing ability on different types of paper.

    Various woods have been used for the pencil casings, from red cedar to the now most commonly used incense cedar. This beautiful wood is then coated with five to eight coats of paint. The traditional yellow paint also has a history. When a very pure graphite mine was discovered in China in the 1800's, pencils made with this high quality Asian graphite (no clay necessary) were painted yellow to distinguish them from the rest. Erasers are added and various markings are then stamped onto the pencil shafts. Did you ever notice the word Ticonderoga stamped on many of them? Fort Ticonderoga, a Revolutionary War fort in upstate New York, is near one of the purest graphite deposits ever known at 99.9% pure carbon.

    We don't advocate that you try this, but a pencil will on average write about 45,000 words, or a line 35 miles long! It is claimed that such a line will in fact even conduct electricity because graphite is a known conductor. Colored pencils are made from chalk, clay, or wax mixed with binders and pigments; compare writing with some of these alongside your regular pencils. If it is possible for you to get a sample of a chunk of graphite (maybe at a store that sells gems, minerals, and fossils), take a close look at it and compare it to the stuff in your pencil.
