While students usually do well with naming binary ionic compounds of fixed charge, many students struggle with naming ionic compounds that contain ions of variable charge. This activity uses a technique often found in humanities classes, a gallery walk, as a guided inquiry experience harnessing real-life applications of several sets of related compounds to address many common misconceptions and lead students to discover the meaning of the Roman numerals when naming and writing formulas for these compounds.

Teaching during COVID was challenging; however, a few positive results surprisingly emerged. For one, Josh Kenney filmed a small library of chemistry lab videos for use in virtual chemistry labs after his school switched to remote learning. At first, he wasn't sure if he would continue to use those videos when his district returned to in-person instruction until he discovered that they would make excellent pre-lab assignments.

When introducing acid-base theory, the concept of indicators and their pH color changes is usually discussed. To illustrate some color transitions to students, a classroom demonstration has been devised based on a memorable scene from Disney’s 1964 movie Mary Poppins.
