Chemical Reactions is a topic that unites a number of skills from formula writing, balancing equations, predicting products and solubility to name a few. On January 13th, 2022, Sarah English shared her unit covering chemical reactions in this ChemBasics Talk. You can view a recording of her presentation and access materials she has suggested.
This blog post includes short descriptions of demonstrations and props that Dean Campbell has used while teaching his collegiate General Chemistry I course.
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
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.
Gas Laws are an essential and easily accessible area of chemistry to understand. They can be an excellent foothold into the inner workings of chemistry. On December 9th, 2021, Daniel Radoff shared his unit covering gas laws in this ChemBasics Talk. You can view a recording of his presentation and access materials he has suggested.
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 .
