This study outlines the effect on the colour of anthocyanin-containing solutions when mixed with caffeine. Given the diversity of anthocyanin structures available from other vegetables, fruits or flowers, there is great potential for series of open-ended experiments for students in classes or science clubs to investigate.

The Diet Coke and Mentos reaction is used as the basis for this hands on experiment. Students work in groups to research, test, and adapt as needed with the goal to get the highest possible geyser!

Interested in expanding your instructional portfolio? What about getting involved with CUREs (Course-based Undergraduate Research Experiences)? If so, check it out some more.
I’d like to report on one of the end-of-year research projects that two of my general chemistry students completed during class this year. If you’d like read more about these end-of year research projects in general, click here.
You may have read Sarah Kong's recent blog post on inquiry on this site. I thought I would give a description of one way I incorporate inquiry learning into one of the chemistry courses I teach.
