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. 

    Lightening with Lemons

    Kids, how much do you know about lemons? Here is a very quick and easy test of the power of lemon juice. Have an adult partner make a mug of hot tea for you from a teabag. Use a white or clear mug so that you can easily see the color of the tea. Now take a fresh lemon wedge and squirt in a few drops of the juice. Upon stirring, certain kinds of tea will instantly lighten up considerably, "magically", right before your eyes. In some cases this works so well that you can make a magic trick out of it. Squirt the lemon juice into a spoon first, out of sight, and then stir it in the tea to watch the color change. Try different types of teabags to see which work best. I have found that the best are the so-called "black" teas (see "Chemistry in a Teabag" from this column in October 1998), such as: regular Lipton tea, Superior orange pekoe & pekoe cut black tea, and Pickwick English Blend traditional black tea.

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

    What appears to be happening is a type of mild bleaching process. In fact, the vitamin C (ascorbic acid) in lemons is known to be a bleach (see another one of our columns, "Clearly it's Vitamin C" from October 1999). Bleaching is the process of removing the natural color of something (cloth, paper, wood, food, etc.). Chemists call the processes either "oxidizing" or "reducing". Vitamin C is an organic compound, which means that it contains carbon, hydrogen, and oxygen (the formula is actually C6H8O6). It happens to oxidize very easily, which means that it is a good reducing agent. Tannins or other highly colored organic molecules in the tea are reduced when the ascorbic acid is oxidized.

    If you were to stain a white cotton rag with some black tea and let it dry, you could try to remove it by spotting with lemon juice and letting it dry in the sun before washing. This might also work if tea were to accidentally stain a t-shirt, tablecloth, or linen napkin.
