This post focuses on the virtual chemistry laboratory activities created for students pursuing a bachelor of science degree in Primary Teacher Education at the University of Bologna.

The classic classroom or lab activity using coin flips to illustrate the first order kinetics of radioactive decay is connected to the tragedy of radiation exposure of workers at facilities using radium-containing luminescent paint. Some of the chemistry related to the contamination of these “radium girls” is explored, with connections being made to the Principles of Green Chemistry and the United Nations Sustainable Development Goals.

There are some simple ways to break chemical bonds with microscale techniques.

A new lesson that uses PES evidence to drive the instruction that would allow the students to identify the limitations of the Bohr model and introduce the Quantum Mechanical Model .

Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)₂ in milk of magnesia.
