GENERAL WEATHER RECORD 1 



1. As assigned by the teacher, collect and tabulate the 

 data called for below : 



2. From the data gathered above, and from the tabulated 

 averages and totals, seek to discover : - 



( (a) The prevailing wind characteristic of any season. 



(6) The relative amount of precipitation by months and 

 by seasons. 



(c) Any seasonal round of clear and stormy weather. 



(d) The temperature ranges and averages for the differ- 

 ent seasons. 



1 See footnote of lesson on Temperature Records. 



2 By use of a circle (O), a clear, partly cloudy, or overcast sky may be 

 shown by the degree of shading; an inclosed R = rain, and an S = snow. 



Note 1. Some one in the community may have a barometer from which 

 readings can be taken in case the school does not possess its own instrument. 

 If necessary, omit the pressure readings, as well as (/) and (h). 



Note 2. A sufficiently good weather vane may be made and mounted on 

 the schoolhouse by any local mechanic, or by one of the older pupils. 



Note 3. Where a rain-gauge (gaj) is not available, a tin can with straight 

 sides (such as a large-size baking-powder can) may be set into a light frame- 

 work to keep it from being blown away. Put the can out in the open away 

 from trees and buildings. Using a foot rule graduated to 16ths of an inch, 

 measure the depth of water in the can, always holding the rule vertical.
