What reading level is Elementary Biology Plant Animal Human book?
To quickly assess the difficulty of the text, read a short excerpt:
To determine the breathing capacity of the lungs.
Laboratory demonstration.
Fill a large tray half full of water. Mark on a gallon bottle the level of 1, 2, 3, and 4 quarts; completely fill the bottle with water, and invert it in the tray, just as was done in collecting oxygen and other gases (P. B. , 10). Beneath the mouth of the bottle insert one end of a glass or rubber tube. Now take in a deep inspiration, filling all parts of the 132 HUMAN BIOLOGY lungs as completely as possible, then slow...ly exhale, blowing the breath through the tube. Make sure that only one complete expiration is carried on, and take care that all the expired air is collected in the bottle.
1. Describe the way the experiment was carried on.
2. Note the number of quarts occupied by the expired air in the bottle, and record this in your notebook.
3. What do you conclude, therefore, as to the amount of air that may be forced out of the two lungs of the individual who performed the experiment?
4. (Optional. ) Ask the pupil who has the highest record of differ- ence in chest measurement before and after inspiration (187) and also the student who has the least difference in the two figures, to try the experiment.
