A Manipulative Paper Tool for Teaching Organic Nomenclature: Part 3- Common Names of Major Classes of Organic Compounds

This is the third in a series of classroom activities using paper tools to teach organic nomenclature. This post covers the two common naming systems used for carboxylic acids and derivatives, and second for alcohols, thiols, ethers, amines, and ketones.

A Manipulative Paper Tool for Teaching Simple Organic Nomenclature: Part 2, IUPAC Naming of Major Classes of Organic Compounds

To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.

Energizer Lab with Virtual Options

In this lab, students connect the workings of an electrochemical cell in the lab with the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process. Although this lab was previously highlighted on ChemEd X, there are now virtual options offered!

Organic Chemistry and Tree Fruit: The Control of Ethylene-Induced Ripening of Fruit in Cold Storage Warehouses

Ethylene, C2H4, a volatile plant hormone stimulates fruit ripening and is also released during ripening. This post explains the role of ethylene in ripening and presents how the chemical identity of the ethylene scavenger used to suppress premature ripening during storage was determined.

An Upcycled Teaching Aid for Ionic Formulas

Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.

Creating Interactive Particle Diagram Activities for Online Instruction

Many teachers have students draw models and diagrams to help them illustrate how matter behaves. Teachers can uncover and address possible misconceptions quickly using this strategy. The author describes how to create interactive particle diagram activities that are easy for students to use online. This strategy is applicable to almost any particle diagram and should be useful for teachers during virtual lessons.
