    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. 

    A Glowing Skull

    Kids, Halloween is the perfect time of year to try out spooky mad scientist projects. With some laundry detergent you can make a glow-in-the dark skull that you can put on your sidewalk or window that will be invisible during the day but will glow at night.

    Materials

    • liquid laundry detergent or powdered detergent mixed with a little water
    • sponge or paper towel
    • if you need help drawing a skull then find a stencil (see link below)
    • thick paper
    • black light 

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

    Make the Decoration

    1. Cut out the shape of a large printed skull on a piece of thick paper and then cut out the eyes, nose, and mouth.
    2. Dampen a sponge or paper towel with the liquid laundry detergent. You want it wet enough to deposit the color, but not dripping wet.
    3. Blot the paper with the detergent-coated sponge to fill in the shapes of the skull.
    4. Hang the skull with the wet side out. Shine the black light onto the skull when you want to see it. Turn the light off when you don't want to see it.
    5. This project works well using a sidewalk, wall, or windowpane instead of paper. In this case you’ll use a cut-out as a stencil. If you ‘paint’ on your porch you can switch out the normal light bulb with a black light bulb. Or you can use a black light on an extension cord and put the decoration anywhere. Wash away the picture when Halloween is over.

    How It Works

    Laundry detergents contain brightening agents that glow when exposed to light, especially ultraviolet light like in sunlight or under fluorescent lights. When you shine a black light on detergent you get a very bright glow. The glow is bright enough that you don't need total darkness to get a nice effect. One of the most common classes of molecules with this property is the stilbenes (see below for more information) which absorb energy in the UV portion of the spectrum and re-emit it in the blue portion of the visible spectrum.

    Stilbene: diarylethene, a hydrocarbon consisting of a cis-ethane double bond with a phenyl group on both carbon atoms; derived from the Greek word stilbos which means shining.
