Lab Report 8 (Intermolecular Forces & Polarity) was submitted today.
We began Lab 9: Types of Solids (A Qualitative Analysis Guided Inquiry Activity) today by examining the prelab exercises and working on characterizing solids of different bonding types (ionic, nonpolar covalent, polar covalent and metallic) by running various chemical and physical tests. Today we visited Lock Haven University to attend their Nanoscience Open House program. Students learned about what nanoscience and nanotechnology is, how it applies to our everyday lives through demonstrations run by students and faculty, and learned about the learning opportunities in nanoscience offered by both Lock Haven University and their partnership with Penn State University. We wrapped up discussion of Lab 8 - Intermolecular forces and polarity with a discussion of how intermolecular forces play a role in physical properties of liquids like surface tension, vapor pressure and boiling point. Students then used the Types of Solids POGIL activity to investigate the relationship between the type of solid (ionic, molecular, network covalent, or metallic) and the properties (fundamental unit makeup, melting point, enthalpy of fusion, solubility and conductivity) it exhibits. This activity will serve as a good resource for students as they develop a procedure for identifying an unknown solid based on its observed properties in Lab 9.
HW: Watch the 2 videos on EDpuzzle about nanoscience and review Sect. 12.9 in the textbook in preparation for tomorrow's field trip to Lock Haven University for the Nanoscience Open House. |
