The geosciences utilize a wide array of instrumental and analytical tools and technology to identify, quantify and explore Earth materials, and test hypotheses using their physical and chemical properties. The laboratory setting can thus provide a rich environment for student learning. This round table discussion will facilitate conversations about the knowledge, skills, and habits of mind that are particularly pursued and strengthened while teaching in the laboratory setting or with laboratory-derived data. Desired outcomes are the exploration of our shared experiences, as well as an inclusive prospectus of 'analytical thinking,' as steps toward codifying the best practices for achieving learning goals 'in the laboratory.'
