ees 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?"
I. KEEPING WELL. 1. Why do our bodies need "housecleaning"? How do we
get rid of the waste part that is a gas? Of the part that is water?
What carries the carbon dioxid to the lungs? What carries the waste
water to the sweat tubes and the kidneys? What other waste is there to
be gotten rid of? 2. Suppose that you and your chum each have an equal
chance to take a bad cold from someone else; your chum catches it, and
you don't. What might be one reason why you don't? Place your hand
over your liver. How can you keep it in good working order? 3. What is
the bladder? Why is it so very necessary to empty the bladder
regularly? When you perspire freely, how does that help the kidneys?
II. SOME FOES TO FIGHT. 1. You have seen moldy bread? What is, the
mold? What makes it spread? 2. Suppose you take some pieces of moldy
bread or potato and turn a glass jar or bowl over them. Catch a few
flies and put them under the glass, and leave them to crawl over the
moldy food. After a day, put the flies under another glass with some
pieces of fresh bread or potato. If you find that the fresh food
quickly becomes moldy, how will you think that the mold germs came to
it? (If you keep the jars in a warm place, the germs will grow faster,
and you won't have so long to wait before you can see the mold.) 3.
What other kinds of germs do flies carry? How do they carry them? 4. A
Board of Health caused a liveryman to be fined because he allowed a
manure pile to remain behind his stable. Why was his act
