THE RADISH 
Material 
Three or four scarlet radishes per pupil. Knives; small pieces of black 
paper. At least one radish in full leaf should be given to each pupil, but 
for the study of the root itself the quality of the leafage is of no conse- 
quence. Two grades of radishes are usually to be found at the green- 
grocer’s, the cheaper being the stale radishes, with wilted and damaged 
leaves. As part of the object of this lesson is to give the pupils an idea 
of a whole plant, it is necessary that some of the radishes should be quite 
fresh. 
Laboratory Work 
l. Take a radish in your hand and notice the co/ov and 
shape; the green leaves; the long, pointed, taillihe 
root below the round part of the radish. 
2. Is the radish the same color all over? Describe 
this. 
3. Examine the radish carefully. Do you find any 
small hairlike roots growing from it? Where are 
these, on the round part, or on the long, white 
root? 
4. Has the radish a sme/7? Describe it. 
5. Pinch the radish with your thumb. Has it a pinch- 
sound? Is the pinch-sound sharp and clear, or 
rather dull? 
6. Select your best radish. Hold this with the leaves
