OBJECTIVES AND OUTCOMES

  • Design and conduct experiments, using a broad variety of experimental techniques, and interpret the data obtained to draw conclusions about whether the results do or do not support a hypothesis being tested and whether the experimental design was appropriate.
  • Work collaboratively with other students and with faculty, understanding that most scientific knowledge/conclusions draw(s) on multiple sources of data and multiple experimental approaches.
  • Learn “best approaches” for conducting experiments including laboratory safety, data replication and quality control, record keeping, and other aspects of “responsible conduct of research”.
  • Gain familiarity with an area of science such that the students can present their work to a professional audience and also discuss their work with a general audience.
  • Develop problem solving skills and analytical thinking skills.
