Materials chemistry

Evaluation Methods: 

assessment of students will be preformed by grading their answers to the questions in the activity.

Description: 

This is a 1 Figure lit discussion (1FLO) based on a Figure from a 2015 JACarticle on synthesizing conductive MOFs. This LO introduces students to Metal-Organic Frameworks and focuses on characterization techniques and spectroscopy. 

Prerequisites: 
Corequisites: 
Course Level: 
Learning Goals: 

As a result of completing this activity, students will be able to...

  • define what metal-organic Frameworks and Post-synthetic Modifications are
  • understand MOF terminology and notation
  • discover how mass transport and electron mobility effect conductivity
  • calculate energies of electronic transitions in electron volts
  • make connections betweeen diagrams and material sturctures
  • compare optical and microscopy techniques
  • discover the concept of photocurrect and how it could be used in different applications
Implementation Notes: 

Students should be able to complete the activity without any prior knowledge of MOFs, although some introduction to MOFs and UV-vis absorption spectroscopy would be nice.

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner, James Madison University

During our first fellows workshop, the first 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.

Venn Diagram activity- What is inorganic Chemistry?

Submitted by Sheila Smith, University of Michigan- Dearborn
Evaluation Methods: 

I did not assess this piece, except by participation in the discussion

Evaluation Results: 

I asked my students to write an open ended essay to answer the question (asked in that first day exercise): What is Inorganic Chemistry.

Interestingly, 2 of my 15 students drew a version of this Venn Diagram to accompany their essays.

Description: 

This Learning Object came to being sort of (In-)organically on the first day of my sophomore level intro to inorganic course. As I always do, I started the course with the IC Top 10 First Day Activity. (https://www.ionicviper.org/classactivity/ic-top-10-first-day-activity).  One of the pieces of that In class activity asks students- novices at Inorganic Chemistry- to sort the articles from the Most Read Articles from Inorganic Chemistry into bins of the various subdisciplines of Inorganic Chemistry.  As the discussion unfolded, I just sort of started spontaneously drawing a Venn Diagram on the board.  

I think Venn diagrams are an excellent logic tool, one that is too little applied these days for anything other than internet memes.  This is a nice little add-on activity to the first day.
 

Your Venn diagram will likely look different from mine.  You're right.

 

Learning Goals: 

The successful student should be able to:

  • identify the various sub-disciplines of inorganic chemistry.  
  • apply the rules of logic diagrams to construct overlapping fields of an Venn diagram.

 

Prerequisites: 
Corequisites: 
Equipment needs: 

colored chalk may be handy but not required.

Implementation Notes: 

I used this activity in conjuction with a first day activity LO (also published on VIPEr).

I shared a clean copy (this one) with the students after the class where we discussed this.

 

Time Required: 
10-15 minutes
