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 Medical Membrane Mimic

    Kids, have you ever heard of kidney dialysis? Kidneys are essential for keeping the proper chemical balance in our blood. They perform a wonderful balancing act of filtration and osmosis that is not only essential to life, but is extremely complicated. In very simple terms, the kidneys filter blood in order to pass some dissolved salts, any toxins, urea, and creatinine, along with a little water. When the body digests proteins, urea is formed. But if too many urea molecules build up due to faulty kidneys, they can cause serious diseases. So, doctors and chemists have worked together over the years to perfect a process called hemodialysis. Chemists have especially helped in creating the special artificial membranes now used (hollow polysulfone fibers), which filter out urea but leave all the other beneficial molecules behind (like red and white blood cells and essential nutrients).

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

    This is all hard to imagine, so here we describe an experiment testing a simple membrane model. In dialysis, small molecules pass through a membrane by diffusion. It¹s like dust blowing through a screen window while keeping bugs out. Diffusion also predicts which direction the molecules will move, which is from more concentrated to more dilute areas. Here a plastic bag will be the membrane. Iodine, starch, and water are the molecules. Starch and iodine combine to make a dark blue product and this will be the visual test of your model.

    Make a thick cornstarch mixture of 1 tsp (3 gm) cornstarch in 1/8 cup (20 ml) water. Put 3/4 cup (180 ml) hot water in a thick clear glass (like a clear coffee mug or a 250 ml beaker). Slowly stir in the cornstarch slurry. Have an adult partner put just under 3/4 cup (150 ml) water and 1 tsp (5 ml) tincture of iodine in another clear glass. Cut off the top (ziploc side) of a ziploc sandwich bag (not a freezer or storage bag). Pour about 1/4 cup of the cornstarch solution into the bag (cleanly!). Close the bag tightly with a twist tie. Gently set the bag in the iodine solution without letting the twisted top get wet. Observe every 3 min for 15 min. Check for color changes. Iodine molecules in the solution (orange) will flow by diffusion through the pores in the bag to the inside, where there is no iodine yet (flow is from concentrated to dilute). When iodine bumps into cornstarch molecules, they react to make the dark blue complex. Which molecules were able to travel through the pores of the bag, and which were not? What does this tell you about the size of the molecules, the size of the pores, and whether this is a good model of kidney dialysis?
