🫁One breath travels a long way before it does any work, and these notes let students trace every step of that trip. With sketch notes, a breathing rate lab and a lung model to build, the system stops being a diagram to memorize and becomes a process students can follow, measure and explain.

These Respiratory System Notes give grades 6-9 a clear, sketch-note route through the human respiratory system in a 37-page black and white PDF. The notes follow a breath from the nose to the alveoli, so students meet each structure in the order air meets it, not as a list to memorize.
The sketch notes come in four versions to fit different students. Level 1 offers guided notes with a word bank, Level 2 offers guided notes without it, an open version leaves room for students to write in their own words, and a color-coded complete version shows the finished notes. Every version uses the same twelve labels, from the nose and nasal cavity through the pharynx, epiglottis, larynx and trachea to the bronchi, bronchioles, lungs, alveoli, capillaries and diaphragm.
Visual notes carry the ideas that are hardest to picture: how breathing works, gas exchange in the alveoli, how the respiratory and circulatory systems work together, and keeping lungs healthy. Three pages of ready-to-teach lesson scripts, a classroom demonstration, a lung health discussion and discussion questions support the lessons.
Practice keeps the learning active. Students label the respiratory system, follow the pathway of air, put air flow in sequence, match vocabulary, answer a 10-question check and short-answer questions, complete a show what you know activity and finish with exit tickets.
The hands-on work gives students something to measure and build. A breathing rate mini lab includes a data collection table and a results graph, and a build-a-lung model activity lets students see a lung model in action. A 5-day lesson plan, teacher notes, color-coding guide, printing suggestions, classroom uses and safety notes round out the set, and answer keys cover the notes, labeling, vocabulary, checks, exit tickets, lab and model, with sample student responses.
📖 Teaching guide · 13 min readTeaching the Respiratory System in Five Days: Pathway of Air, Breathing and Gas Exchange for Grades 6–9Read the guide →The notes follow one breath in order, so students learn the pathway before they meet gas exchange or the connection to the circulatory system. Four sketch-note versions, a lab with data to graph and a model to build give the same ideas in words, pictures and hands-on work, which helps the sequence stick.
It is written for grades 6–9 and fits biology, life science and health units on the respiratory system, human body systems and gas exchange.
There are four versions of the sketch notes: Level 1 guided notes with a word bank, Level 2 guided notes, an open notes version, and color-coded complete notes.
A breathing rate mini lab with a data collection table and a results graph, plus a build-a-lung model activity.
The set includes a labeling page, a pathway of air activity, an air flow sequence activity, a vocabulary match, a 10-question check for understanding, short-answer questions, a show what you know activity and exit tickets, all with answer keys.
