State Fair booth spotlights assistive technology Aug. 18

The Iowa State Fair is ongoing at the Iowa State Fairgrounds in Des Moines, and The University of Iowa will spend Aug. 18 hosting specialized exhibits on organic matter and assistive technology.

UI exhibits scheduled for Aug. 18:

  • Farming the Climate, Keeping the Carbon, presented by IIHR—Hydroscience & Engineering in the College of Engineering, 9 a.m.–2 p.m. Fairgoers will be able to add different amounts of water to small buckets with various crops and levels of organic matter. They will use a gas analyzer to measure the differing rates of carbon dioxide released from the soil. That information will be entered into a computer model showing statewide effects. Participants can then change the choices of land use in the computer model to see how that affects carbon release patterns.
  • Assistive Technology: Helping Iowans with Disabilities, presented by the Iowa Center for Assistive Technology Education and Research (ICATER) in the College of Education, 3–9 p.m. ICATER, the only center of its kind in the Big Ten Conference, will have several laptop computers, iPods, and iPads to demonstrate and provide hands-on experience with technology designed to help people with physical, visual, and learning disabilities.

The fair continues through Sunday, Aug. 21. Visit for more details about the Iowa State Fair.
