THE PEA 
Material 
Five or six fresh green pea pods per pupil. Pins. (Peas can be obtained 
in the New York markets at almost any time in the year, but in winter a 
good many are apt to be damaged. Allow from two to three quarts for fifty 
pupils, according to condition.) 
Laboratory Work 
1. Lay the pea pods in a row; look at them, and then 
pick out one that seems to you medium sized and 
a good one. Take this in your hand and examine 
it, noticing — 
Color. 
Shape. 
Stem. 
Small leaves at stem end. 
The point opposite the stem end, or “nose.” 
f. The lines running from stem to “nose.” 
2. Notice that one line running from stem to “ nose”’ is 
almost straight. Do you see the groove in this? 
One line running from stem to nose is very much 
curved at the nose end. There is a ridge on this. 
Run your finger along each of these lines; which 
seeins the sharper? Can you tell the two edges 
apart when you feel them with your eyes shut?
