VI. TASTING AND SMELLING. 1. If anyone asked you how a lemon tastes, what would you say? What would you say about sugar? Salt? Pepper? Pickles? Strawberries? Cheese? Onions? Radishes? How did you learn about each of these? 2. What does your tongue do besides receiving tastes? Note in the picture (p. 86) how strongly your tongue is rooted; point to the tip of it in the picture. 3. How does your nose help your throat and your lungs? How else may it help you? 4. Draw a picture to show how air reaches the lungs. 5. What are _adenoids_? How may you know if you have adenoids? If you have, what ought you to do? Why? 6. Where do the men who want to smoke in the open trolley car have to sit? Why? If children breathe tobacco smoke, what effect will it have on them? Why is smoking a foolish habit? How is it often harmful? VII. TALKING AND RECITING. 1. When you are reciting in class, do you think how your voice and the words sound to the other people in the room? Show the class how you can make your speech sound just as you want it to. 2. Give three ways in which you can take care of your throat and voice. Put your hand on the place where your voice is made. How is it made? 3. On your own picture of the throat, show where those little folds of skin are (the picture on p. 86 shows, of course, only the fold of skin, or _vocal cord_, on the right half of the windpipe). VIII. THINKING AND ANSWERING. 1. With two or three of your classmates, play telephone;--one must be "Central" and one "Information" at the central office, and one must receive your message and answer it. A number of the other children may join hands to make a long "wire" on each side of "Central"; they will repeat the message softly from one to another all down their "wire." 2. Now, suppose that you all represent the telephone system in the body. Could you act out this "Body-Telephone" call:--The eye sees a burning match on the floor, and sends the message to its center in the brain; this center consults the memory ("Information") as to what to do. Memory recalls that burning matches are likely to set fire to other things and ought to be put out. So the brain sends a message to the muscles of the foot to get to work and stamp out the flame. In this play, what will you each call yourselves? 3. Make up some other "Body-Telephone" plays. 4. What are some of the messages that are being carried by your nerves, that you know nothing about? 5. Think how many messages a baby stores away before he is ready to answer them; what are some of these? Why can he not answer them at once? What makes his brain and nerves and muscles grow? How can you take the best care of yours? 6. In the picture on p. 96, point to the brain; to the spinal cord. How near the surface of your back is your spinal cord? What keeps it from being easily injured? "ABSENT TO-DAY?"
