This activity is intended for use in a college-level second term general chemistry course, and is designed to engage students in a guided concept development exercise that will help them construct conceptual understanding of how non-volatile solutes impact the boiling point and freezing point of aqueous solvent.
This is an in-class activity that introduces students to the concepts of ionization of strong and weak acids in aqueous solutions and equilibrium constants for acid ionization using two of the domains in Johnstone's triangle of chemistry knowledge, submicroscopic particle level illustrations and symbolic representations.
This POGIL based activity is intended to review general chemistry concepts of atomic structure and to further those concepts with additional attention to d orbitals and radial distribution graphs. The primary model in the activity is The Orbitron website (https://winter.group.shef.ac.uk/orbitron/) with students examining the isosurface and radial distributions for a variety of orbitals.
These slides were originally developed as a part of an Earth Week presentation for a general audience, but can also be used as part of a general chemistry course or any course with electrochemistry. They provide a modern context and relevance to how lithium-ion batteries are produced and function.
The second cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
This is an in class activity to provide students the opportunity to practice:
Our CHEM145 is offered once every two years: TR 75 min synchronous lectures, F 4 h in-person lab.
This worksheet was designed as an in-class, group activity in a flipped classroom. It relies on an understanding of the octet rule and common charges of various elements, as well as basic nomenclature of ionic compounds. The worksheet teaches students to balance simple redox reactions (in which only the oxidized and reduced atoms are present) by identifying half-reactions, counting electrons transferred, and multiplying half-reactions to "cancel" electrons.
This is a worksheet designed for a flipped-classroom, in-class activity during the first course in our chemistry sequence. It teaches the basics of Molecular Orbital Theory from a semi-qualitative standpoint, by showing the constructive and destructive overlap of s-orbital "wavefunctions." The activity illustrates the formation of the bonding and antibonding molecular orbitals in H2, shows its molecular orbital diagram, and introduces the concept of bond order.
Professors Kari Stone and Dan Kissel fro Lewis University describe the transition to a remote general chemistry course through a flipped curriculum using mastery-based grading. In particular, the development and implementation of a element project is discussed as part of the 17th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable) on 3/4/2021
