What reading level is Graded Lessons in Hygiene book?
To quickly assess the difficulty of the text, read a short excerpt:
One of the bronchi, or large air tubes, goes to each lung. Below this main division the air tubes divide again and again, many times, until we have the finest possible air tubes, like the little, fine, netted veins of a maple leaf. At the end of each of these little tubes is a tiny air sac. There are thousands upon thousands of these air sacs, and together they make up the two lungs. A lung is a soft, spongy piece of flesh made up of a collection of air sacs. Each air sac of the lung is like a ...little toy balloon, filled with air each time we inhale. You feel and see your chest expand as each one of these thousands of air sacs is filled. When the breath rushes out as we exhale, the chest falls again. Take a tape line and see how many inches you measure around your chest when you inhale and fill the lungs every air sac with all the 128 GRADED LESSONS IN HYGIENE.
air they can contain. Now exhale every particle of air that you can, and measure your chest to see how much smaller it is.
The lungs fill the upper part, jof the body just below the Voice-box FIGURE 46.
