THE ORANGE 
Material 
One orange for each pupil may be made to answer, provided alternate 
pupils cut cross aud vertical sections and exchange. Small, cheap oranges 
will do as well as large ones. 
If the children are to take the segments out of their own oranges, they 
should be told the day before to bring towels, the ends of which should be 
wet before the lesson. 
Laboratory Work 
1. Examine the orange and notice its color and shape. 
2. Is there any difference in the two ends? Do you 
find either a small brown or green button, or a small 
round hole at one end? Is there anything like 
this in the lemon? 
3. If there is a button in the buttonhole, take it out 
and look into the buttonhole. You will find on 
one a ring of small dots, on the other a ring of 
small holes which exactly correspond. On which 
are the dots? 
4. Has the orange a smell? Rub the skin hard on one 
hand and see if the smell is plainer. 
5. Has the orange a pinch-sound? Guess why it has 
not. 
G. Press the orange to your cheek or forehead. Put it
