Looking for a fun, no-prep way to review the basics of cellular respiration? This Introduction to Cellular Respiration Cipher Puzzle gives students an engaging way to practice key vocabulary and concepts related to how cells release energy from food.

Students read each clue, identify the correct cellular respiration term or concept, use the cipher key to find the matching number, and convert each number to a letter. Once all 20 questions are complete, students write the letters in order and add spaces to reveal the hidden message.

Please have a look at the preview to see how it works.
