    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. 

    Lemon Battery

    Kids, how would you like to make electricity with a lemon? You'll need a lemon, a galvanometer, 2 stiff copper wires, a large paper clip, and scissors.

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

    If there is any insulation on the ends of the wire, have an adult strip it off. Untwist the paper clip and twist the end of one of wires around it. Squeeze and roll the lemon to loosen the pulp inside. Make two small cuts in the skin of the lemon an inch or so apart. Insert the bare wire and the paper clip through these cuts into the juicy part. The two wires should be close but not touching. Connect the free ends of the two wires to the terminals of the meter.

    Now watch the meter move! What's happening here? Electrochemistry causes the two different metals (the copper wire and the iron clip) in the acid (lemon juice) to draw electrons away from one wire towards the other. They flow out fo the lemon through one wire, go through the meter and then enter the lemon by the other wire.

    You can even try to make your own galvanometer (an instrument designed to detect electrical currents) if one isn't available to you. You'll need a compass, 15 feet of bell wire (hardware store), and a small rectangular cardboard tray. Place the compass in the cardboard tray. Scrape off 1/2" of insulation from each end of the bell wire. Starting 6" from one end, wind the wire tightly around the box, circling it at least two dozen times. Leave another 6" of wire free on the other end of the tray. Rest your homemade galvanometer on the table horizontally and turn it until the compass needle is parallel to the coil of wire. Use these bell wire ends to attach to your lemon and paper clip.
