Visitor StudiesFront-End Studies

This front-end study was prepared for an October 1997 workshop held at the ASTC annual conference in St. Louis, Chemistry Exhibits That Work: What Visitors Know

Chemistry and the Periodic Table: Front-End Study for Chemistry Lab
Contributed by Becky Wynne, Oregon Museum of Science and Industry

The purpose of this study was to gather information about the public's interest in chemistry and their knowledge of the Periodic Table.

The data was collected between December 18 and 22, 1991, from OMSI's general visitor audience. The visitor's knowledge of the Periodic Table was specially highlighted and they were asked to determine which 20 of the 71 chemical products listed they were most interested in. Paula Baer was the project evaluator, and Amy Shreve assisted with data collection.

Method
One hundred OMSI visitors were randomly approached and asked to complete questions while a staff person waited nearby.

Conclusions

  • Our sample was predominantly (71%) from the Portland, Oreg. metropolitan area. Representation from other areas in Oregon was 153% and 11% from other states.
  • The 71 products were ranked, showing which were most popular to the visitors. This will be useful in determining which products are selected for the exhibit.
  • The survey showed that two-thirds of the respondents were interested in the historical background of the chemical products.
  • Most (71%) said that chemistry is very important to life, but 69% responded that they only occasionally came into contact with chemicals. This misconception would be addressed in the exhibit.
  • Most people correctly identified the Periodic Table and knew what the letters/symbols stood for, but more than half did not know why it is organized the way it is.

    20 products visitors are most interested in (and number of visitor responses):
    (Selected from list of 72 products)
