Smoke-free and Smoker’s Lung Display

Simple but effective way of showing how smoking damages the lungs. Comparing the air sacs of the lungs to bubble wrap, this 3-D model of two lungs shows the bronchial air passages of two bubble wrap lungs. The smoke-free lung is pink and healthy, with all the air sacs intact. The smoker’s lung is black from tar, has holes burned into the air sacs to represent emphysema, and has cancerous growth and a pool of phlegm. The background chart explains the differences between the smoke-free and smoker’s lungs. Also includes a handout. Display is protected with acrylic cover and can be wall-mounted. Grade 2 and up.
