Chemical Information Available on the Web

Submitted by Matthew Riehl / Minnesota State University, Mankato on Thu, 06/30/2016 - 22:21
Description

This exercise introduces students to many chemical resources found on the internet.  Rather than being geared for upper-division chemistry majors, much of the material introduced is appropriate for freshmen and sophomore level students (although more advanced students will also benefit from the exercise).  The “web guide” contains links to many search engines and resources with brief descriptions of each while the “web report” has a number of exercises that asks students to search for chemical information.  The assignment is self-guided; students are encouraged to choose topic of interest t

Fischer-Schrock Personality profile

Submitted by Adam Johnson / Harvey Mudd College on Wed, 06/29/2016 - 14:16
Description

This is a powerpoint presentation that was developed for and used at the 2016 VIPEr workshop on Organometallic chemistry at the University of Michigan. Organometallic chemistry is a broad field, and we have divided ourselves into different classes based on what we study. For example, the reactivity of the third row metals is often quite different from that of the fourth/fifth rows. Early (high oxidation state with anionic ligands typically) and Late (low oxidation state with neutral ligands typically) metal complexes have different properties and d electron counts.

"Flipped Laboratory": A Discussion-based Electrochemistry Experiment for General Chemistry

Submitted by Samuel Esarey / University of Michigan on Mon, 06/27/2016 - 16:43
Description

This learning object is aimed at getting students to think critically about the data they collect in lab as they collect the data similar to how chemists typically conduct research.  They will be given a pre-lab video and a procedure prior to lab, conduct the experiment, and then upload their data to an Excel spreadsheet.  Students will then stay in their group to discuss the questions given to them on the worksheet in class with the instructor, and are allowed to continue working on them as a group up until the due date.

Reaction Report

Submitted by RSwails / Lafayette College on Mon, 06/27/2016 - 15:24
Description

Students are asked to choose a type of reaction from a set list (included), determine appropriate starting materials and the resulting product and present the reaction as though they accomplished it in the laboratory setting (5 min oral presentation with a 1 page paper).  I asked the students to perform both a rough draft presentation (to me) and final draft presentation (to all students in laboratory).

Writing Lab Reports

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 03/02/2016 - 14:14
Description

Each spring semester I take on the task of teaching and grading full lab reports for my senior advanced inorganic chemistry class. For most this is their first experience writing a document of this magnitude as most other labs they have previously taken require either lab report sheets or the occasional abbreviated lab memo. As I read their lab reports each year I am reminded both how challenging it is to teach writing (more specifically scientific writing) and to grade the reports objectively.

Iron Cross-Coupling Catalysis

Submitted by Laurel Goj Habgood / Rollins College on Wed, 09/16/2015 - 13:08
Description

In this experiment, students will synthesize and characterize an iron complex followed by completion of two series of catalytic cross-coupling reactions mimicking the methodology utilized by organometallic chemists to balance catalyst efficacy and substrate scope.  Initially the complex Fe(acac)3 [acac =  acetylacetone] is prepared.  Two sets of catalytic reactions are completed: one comparing different iron catalysts (Fe(acac)3, FeCl2, FeCl3) while the other compares substrates (4-chlorotoluene, 4-chlorobenzonitrile, 4-chlorotrifluorotoluene).

Antibacterial Reactivity of Ag(I) Cyanoximate Complexes

Submitted by Kari Young / Centre College on Sat, 08/22/2015 - 14:09
Description

In this experiment, students will synthesize and characterize one of three Ag(I) cyanoximate complexes as potential antimicrobial agents for use in dental implants. This experiment combines simple ligand synthesis, metalation and characterization, and a biomedical application. The complexes are both air and light stable.

Kayaking to Lake Washington

Submitted by Fabiola BL / The Cooper Union for the Advancement of Science and Art on Fri, 07/03/2015 - 00:51
Description

Leisure activity after days of hard work at the IONiC VIPEr workshop in Seattle, WA.

Participants rented kayaks and paddled around the lake for about 90 minutes.

Pre-requisites: Application of a generous amount of sunscreen.

The original plan was to paddle to Lake Washington, but no directions or map was provided. So given the lack of navigation skills and familiarity with the area it is no surprise that only one kayak made it all the way to lake Washington (Go team FBL & KMH!).

Peer Review - How does it work?: A literature discussion with a focus on scientific communication

Submitted by Mike Norris / University of Richmond on Thu, 07/02/2015 - 20:21
Description

This learning object is based on discussion of the literature, but it follows a paper through the peer review process.  Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots.  There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.
