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. 

    Sunscreen Savvy

    Kids, now that summer is upon us would you like a way to prove that a sunscreen works without using your own skin as the test? For this activity you will need a sheet of black & white newspaper or construction paper (red or dark blue work best), four zip-seal sandwich bags, two sunscreens (one lotion and one spray, both labeled “clear”, and both having the same sun protection factor - SPF), a piece of fabric, and a sunny outdoor location. 

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

    Cut four pieces from the newspaper or construction paper and the fabric, sized to perfectly fit inside the plastic bags (about 5” x 6”). Place one piece of paper in each plastic bag so that the paper lies flat. Treat the bags as follows:

    • Bag #1. Coat one side of the bag with a thin layer of sunscreen lotion.
    • Bag #2. Coat one side of the bag with a layer of spray sunscreen.
    • Bag #3. Place the fabric in the bag to cover the paper and lie flat.
    • Bag #4. Leave as the untreated control.

    Seal each bag. Place the four bags in a sunny location outdoors with the treated side up. You may need to anchor them so they remain flat and don’t blow away. After 1 or 2 sunny days, open the bags to observe the paper.

    The paper in the untreated bag should fade or turn yellow (newspaper) after sun exposure. But the paper samples underneath layers of sunscreen remain protected from the sun’s rays and should retain their original color. The paper under the fabric should be somewhat affected; the degree depends on the fabric used. For example the SPF of white cotton is much lower than that of denim.

    Sunscreens work either by absorbing or by scattering UV rays. Sunscreens that absorb UV rays contain organic molecules, usually octinoxate and/or avobenzone. Sunscreens that scatter UV rays contain inorganic compounds such as titanium dioxide (TiO2) or zinc oxide (ZnO). The smaller the inorganic particles are, the more transparent or “clear” is this type of sunscreen.
