234 THE NATURE-STUDY REVIEW U: 7 -oct., 1908 



Fourth experiment: To show whether plants as well as 

 animals breathe, giving out carbonic acid gas. Lime water 

 was poured into a glass, and upon blowing through a glass tube 

 the lime water became milky. Now, would plants have the 

 same effect upon lime water? Peas were soaked over night and 

 a glass quart jar was half filled with them. On the top of peas 

 was placed a small glass containing lime water and the cover of 

 the glass jar was screwed on. In less than an hour the lime 

 water presented a milky appearance. Plants breathe the same 

 as human beings, giving out carbonic acid gas. 



Each pupil kept a record of the experiments performed, one 

 of which reports is given below. 



Report on Experiments, by Elsie M. Long, VI grade 



We put soil in a glass and turned it upside down in a saucer of water and 

 left it there for a week. When we took it up, the water was all through 

 the soil; this proves that water rises in soil. In one glass we put sand and 

 moistened it and in the other glass soil. They each weighed one pound. 

 When we took and weighed them the next week the soil weighed more so 

 it shows water evaporates quicker in sand than in soil. 



We put water in a glass of soil and kept it loosened for three-fourths of 

 an inch. The other one we did not loosen at all. The one we loosened, 

 weighed more so it proves the soil keeps water longer when it is loosened 

 than when it is kept hard. 



A farmer should keep his soil loose as it keeps it much nicer looking. It 

 keeps more moisture and keeps it much longer.
