    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. 

    Dancing Worms

    November, 2015

    Kids, in a variation of Dancing Raisins (ChemShorts for Kids, Feb. 1992; http://chicagoacs.org/articles.php?id=30), let's make some colorful Dancing Worms!

    You'll need gummy worms, baking soda (sodium bicarbonate), water (H2O), vinegar (dilute acetic acid), 2 glasses, and scissors.

    With an adult partner's help, use the scissors to cut the gummy worms in half or into quarters lengthwise. You want long, thin strips of worm. Drop the worm strips in one glass. Add a couple of spoonfuls of baking soda and enough water to dissolve some of the baking soda. If all of the baking soda dissolves, add more until some undissolved powder remains. Let the worms soak in the baking soda solution for 15 minutes to half an hour.

    Pour vinegar into the other glass and drop a baking-soda-soaked worm into the vinegar. What happens? At first, nothing much. But after a while bubbles start to form on the surface of the worm. Then the worm starts to move. After some time, the reaction stops and the worm slows down and stops moving entirely.

    Why Do the Worms Move? The gummy worms wriggle because a chemical reaction between sodium bicarbonate and acetic acid produces carbon dioxide gas. The tiny gas bubbles released by the reaction stick to the body of the gummy worms, eventually merging into bubbles big enough to float part of the worm. If the gas bubble detaches, it floats to the surface while that part of the gummy worm sinks back down.

    Tips for Success

    If your worms never dance then have an adult partner cut them thinner. A thinner gummy worm is a lighter gummy worm and thus much easier to make move. Thin worms absorb baking soda better, too. Or you can try adding more baking soda to the soaking solution or soaking the worms longer. The baking soda needs to get into the gelatin that makes up the worms so that it can react with the vinegar to make bubbles.
