The Science Museum of Minnesota surveyed 16 museum visitors after they participated in the Exploring Measurement: Ruler Activity at NanoDays. This formative testing of the activity assessed the activity’s ability to convey the size of a nanometer, and that scientists need to use special tools when working at the nanoscale.
The Science Museum of Minnesota conducted the StretchAbility program on January 25th, and February 1st, 2010, and the Children’s Museum of Houston conducted the program on November 10th, 14th, and 25th, 2009. A total of 20 paired adult and child groups provided feedback through a survey designed to measure their engagement with and comprehension of the activity. After the activity, evaluators targeted participating children 8 or younger who were verbal for the interview, and gave a survey to the child’s parent to complete. Paired surveys were used due to the lower verbal nature of the younger
A series of interview studies was conducted to determine how museum visitors interpret scale ladders that focus on the nanoscale. These studies look at different versions of an example scale ladder in order to: a.) Iteratively develop a scale ladder that may be used by other informal science institutions. b.) Formulate guidelines to inform the design and use of other scale ladders. Interview questions used for studies 1-3 are included in the appendix of this report.
