SECOND GRADE SPRING WORK in 



LESSON XXXIV 

 WEATHER CHANGES 



What did Jack Frost do last winter ? What traces has he 

 left behind him? What did he do to the soil? to plants? 

 to seeds? Is the ground as hard to plow now as it was in 

 the fall? Has he injured man in any way? Has he aided 

 man in any way? Notice if the trees, fruit buds, fall grain, 

 or stored vegetables were injured by frost. 



What has driven Jack Frost away ? Compare the average 

 weekly temperature for the past month; also the length of 

 the shadow on the shadow-stick. Find the change in the 

 sun's path, and account in a general way for the change in 

 temperature. 



When it storms now, does it rain or snow ? Do you notice 

 any effect of the weather upon plant life? Are any seeds 

 germinating? Have any flowers bloomed? When do the 

 butterflies appear? Watch for the return of the birds. 

 Which appear first ? What influence has the change in the 

 weather upon man and his work ? 



LESSON XXXV 

 KINDS OF PRECIPITATION 



How can we tell when a storm is approaching? Discuss 

 the winds, the clouds, the temperature, and other meteorologi- 

 cal conditions. What kind of clouds always cover the sky 

 when it storms ? What determines whether the precipitation 

 will be rain or snow ? Under what condition is hail formed ?
