    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. 

    Bubble Trouble with Hard Water 

    Kids, you may have heard that the chemical element CALCIUM is very important for strong bones and teeth. Terrific sources of calcium in our diets include milk, broccoli, salmon and sardines. Along with bones and teeth, calcium is also a major part of things like cement, seashells, limestone, chalk, marble, eggshells, and de-icer for icy roads. Sometimes when water flows over limestone or other materials with a lot of calcium in them, the calcium gets into the water. Water that contains a lot of calcium or other minerals is called HARD WATER. One characteristic of hard water is that it makes a soap scum when mixed with soap. It also makes a soap solution much less bubbly. But don't just take our word for it, let's check it out!

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

    Cover a work area with paper towels. Label 3 clear 8 oz plastic cups as "water", "water and plaster", and "soapy water". Pour 1/2 cup warm water into each cup. Add about 1/4 teaspoon of plaster of paris powder to the cup labeled "water and plaster". Stir thoroughly with a plastic straw. Grate 1-2 tablespoons of soap from a bar of soap. Put about 1 tablespoon into the "soapy water" labeled cup. Stir thoroughly with a new straw. Add 1 tablespoon of your soapy water to the "water" and "water and plaster" cups. Do not stir right away, and observe what happens closely. Is there a difference? What do you see happening in one of the cups? Now stir each cup with a separate straw. Do they still look different? Next use a new clean straw to blow gently into each cup. Do you notice a difference in the bubbling? What do you think is the reason? It will help you to know that plaster of paris is a chemical compound called calcium sulfate (made from gypsum).

    [Safety Tip: Please be sure to blow into the liquids. Do not suck the liquid into the straws at all.]
