Respiratory System Summary Cryptogram Puzzle

This fun cryptogram puzzle is about the respiratory system for a human anatomy and physiology or biology course. A cryptogram is a type of puzzle with the encrypted text. In this cryptogram, students will decipher a number code to reveal the letters to form the text of the summary statement about respiratory system.

The header on both student pages has a horizontal letter-number assignment table. Students start the activity knowing the number assignments for six letters. The entire message appears as a series of blank lines grouped into what will become words. There are numbers located under half the letter lines. Students will use their insight to fill in the letters to complete the terms of the puzzle with the help of a word bank table on the third page. Students can keep track of their number-letter assignment findings on the tables on each page.

This cryptogram features the following key terms – alveoli, bloodstream, bronchi, lung capacities, lung volumes, involuntary, nervous mechanism, chemical mechanism, normal breathing, chemoreceptors, diffuse, diaphragm, cartilaginous, negative pulmonic pressure, rhythmic, pleural membrane, pulmonologists, trachea, gases, and homeostasis.

This forty-five minute engaging activity is easy to grade and comes with a full-page key. It reinforces a lengthy summary statement about the respiratory system. This full-period exercise also serves as an ideal lesson plan for a substitute teacher.
