Take a deep breath and dive into science with the Big Breath Respiratory System Model! This hands-on activity brings anatomy to life as children explore how the lungs work through an interactive demonstration. Perfect for classrooms, homeschooling, or STEM lessons, it combines creativity and science in one exciting project.
Students start by coloring the pre-punched lung cards to learn the parts of the respiratory system. Then, they insert the heavy-duty straw and attach the included lung bags. As they blow into the straw, the anatomically correct model inflates and deflates—visually showing how air moves in and out of the lungs.
The Big Breath Respiratory System Model helps children understand the science of breathing while strengthening fine motor skills and sparking curiosity about the human body. It’s durable, educational, and fun—ideal for visual learners and budding scientists alike.
Watch the power of air in action and make science unforgettable with this engaging, hands-on model!
