Lesson to determine the relationships between acid strength, Ka, pH, Molarity, and percent ionization

After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.

Whiteboarding in a Virtual Classroom with Melissa Hemling

On January 26, 2021, Melissa Hemling presented a ChemEd X Talk about “whiteboarding” in a hybrid or virtual classroom. Students collaborate in small groups on to digitally analyze data, create and modify models, and/or complete practice problems. Melissa shares how she uses the digital whiteboards to gauge student understanding and pinpoint misconceptions like she did pre-COVID. You can watch the edited recording of Melissa's Talk and access the document she shared during the presentation here.

Chemistry in General Biology: Is it necessary?

Is it necessary for biology faculty colleagues to spend a month or so covering foundational chemistry in general biology courses then for the remainder of the semester require students to only know a small fraction of chemistry covered? This post briefly looks at what chemistry is needed for general biology.
