    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. 

    Science of Soap Bubbles


    Kids, did you ever wonder what a turtle shell, a bee's honeycomb, a soccer ball, a chicken wire fence, and a bag full of bubbles have in common? All you will need to find out is a quart size zip-lock bag, a plastic straw, and a bubble solution. To make the bubble solution, mix 4 parts of water to 1 part of liquid detergent. For example, measure 1 cup of water and add 1/4 cup of detergent. Add the detergent to the water, and stir gently. Adding about 1/2 teaspoon of sugar makes longer lasting bubbles.

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

    Place 1 tablespoon of bubble solution in the plastic bag. Close the bag almost completely, leaving just enough room to slip the straw into the bag. Gently blow through the straw to fill the bag with bubbles. Now study the bubbles that formed. Are the sides of the bubbles curved or flat? How do their sizes and shapes compare? Do most of them have the same number of sides?
    You'll find that many of the bubbles inside your bag should have six-sides, which makes them hexagons. Many hexagon shapes can be found in nature. Spider webs, some insect's eyes, and certain plant stems are based on this shape.

    How thick is a soap bubble? The film is one of the thinnest things that we can see without using a magnifying glass. It is about 5000 times thinner than a human hair! What's inside the bubbles? It is always a gas, and most have ordinary air inside. The bubbles that you blow contain more carbon dioxide because this is a gas that we exhale. Bubbles in soda pop are filled with carbon dioxide, and those in boiling water are filled with vaporized water or steam.

    [Since different detergents have different bubble-making abilities, you may have to experiment by using different amounts of detergent, water, and sugar until you get the nicest, longest-lasting bubbles.]
