The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
A simple, but tricky experiment is displayed. Can you figure out how the trick was done?
This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.

The unit of acids and bases is difficult for most students in Advanced Placement Chemistry. The variety of various calculations can be overwhelming. The Acid Base Speed Dating Activity engages students in completing a series of problems. Each student is assigned a specific solution and then determines their individual pH to complete their personal “Solution Biography.” Then the speed dating begins! For each date, the students need to find a specific match and determine their combined pH value.
Do you require your students to learn all the element names and symbols? Do your students struggle with chemical nomenclature, chemical equations, or stoichiometry? You may want to consider getting them back to the basics.
“You sank my battleship!” Do you remember this line from a classic commercial featuring the board game Battleship? It sat in my family’s game closet when I was a kid, but it’s popping up again recently, with chemistry twists.
In my high school chemistry class, a unit we cover is that of atomic structure. In particular, given an elements symbol, mass number, atomic number, and charge, the objective would be for the student to determine the atoms number of protons, neutrons, and electrons. I have several apps/program suggestions that can be useful for this purpose.
Over the past two years, I have immersed myself in designing mobile games for organic chemistry: founding a company called Alchemie and building a team to develop these games. The first of our games is called Chairs! (The exclamation point comes from the fact that an app called Chairs already existed in the AppStore.) The game Chairs! is what we call our proof-of-concept. Folks were a bit incredulous when we told them we design games that make learning organic chemistry intuitive and fun.
During our “Periodic Table and Periodicity" unit, we take about 3 days to learn the content and another 3-4 days to practice the content (more for Chemistry 1, less for Honors). One way that I have my students review the content is by playing a board game that I recreated from an NSTA conference a few years ago.
