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.

Coordination Compounds: Independent Study

An independent study on the chemistry topic of coordination compounds and complex ions suitable for AP Chemistry and first-year college chemistry students is presented. This student activity accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions" and is suitable for use by the student to guide their activity.

Complex Ions Lab

This laboratory exercise accompanies the article "". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions. The entire lesson as described in the article also exposes students to how chemical research is conducted and the conflicts and uncertainties that lead to new theories and discoveries.
