Recently as I was mowing my lawn, I noticed that some of the florets on white clover have a slight pink or purple color (Figure 1). Because anthocyanins often impart red, blue, and purple color to plants, fruits, and flowers,^1,2 I wondered if these tiny pink florets in white clover contained anthocyanins.

When the COVID pandemic of 2020/2021is eventually eradicated and more colleges resume in-person laboratory instruction again, many instructors will face the daunting reality that students entering upper-level chemistry classes may have little or no actual hands-on college lab experience having completed their general chemistry laboratory sequence throug

The most common examples of freezing point depression referenced in GChem 1 or Introductory Chemistry (a survey course for non-majors or requirement/recommendation for allied health students such as nursing or radiology) are liquid automobile antifreeze, or road salting during winter.

As a follow-up to the first two activities (Part 1 and Part 2) using paper tools to introduce

In the main museum (the former barracks) an interpretive timeline display summarizing the history of (dishonored and broken) treaties and chronic conflict between the US government and western Native Americans captivated me.

Easy access to the internet has helped to enable many individuals to gather data to serve a collective purpose.

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.

I have always been fascinated by chemical reactions that form shiny, metallic mirrors.
