Teacher Notes

• This activity was chosen as the ChemFun section of the November 2024 issue of Chemistry Solutions.
• This activity was designed to be a fun overview or review activity for students to test their knowledge of chemical measurement. The topics included as part of the questions in this activity would be covered in a typical high school chemistry course.
• This activity could be used as a warm-up/bell-ringer activity near the end of the school year, or shared with students who finish an assignment earlier than others.
• Note that not all of the letters are needed to solve the riddles, some additional letters are included as distractions in an effort to limit a student’s ability to solve the riddles without actually answering the chemistry questions.
• An Answer Key document has been provided for teacher reference.
