They also thought the “airline tickets” I printed for the country for the correctly solved puzzles were an exciting touch.

During one of my classes, one group of students was so excited to complete the puzzles before other groups that they cheered and jumped for joy as if they really had just saved the world.

My students forgot that they were reviewing for a chemistry test because they were having fun trying to solve the puzzles. 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. 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. This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. Therefore, I had to determine the names of countries that could be spelled using the periodic table and whose names could be made out as a result of five puzzles. I decided to create five puzzles to fit within my class time of fifty minutes. I thought it would be fun to solve a mystery whose clues could be used to spell out the name of a country. I personally enjoy Escape the Classroom activities, but I could not find one that fit with my Chemistry class content. Last year, I wanted to create a fun way to review Periodic Table concepts with my students instead of using the same review worksheet I had students complete in the past.
