 MINERALS. 



Fossil animals, teeth, shells, plants, leaves, etc. Identify 

 fossil animals and plants with living things. Conditions of 

 fossilization. Change in earth conditions. Account for fos- 

 sil coral in Michigan. 



ELEMENTARY GEOGRAPHY. 



Variation of temperature before, during and after a 

 storm ; variation of barometer and thermometer. 



Effect of sun's position on temperature. When do shad- 

 ows correspond and differ most? 



NOTE. — Relate fossil animals and plants to Itind and quantity 

 of life extant in remote ages. Compare similar life of tlie present 

 day. 



Pupils should be encouraged to make collections of fossil 

 plants and animals and to look for them in limestone used for 

 building purposes. At first it is sufficient to be able to distin- 

 guish them by sight. 



FEBRUAEY. 



PLANTS.

 strong feet, small wings; aquatic birds — boat-shaped 

 bodies, short legs, webbed feet, or long legs, long neck, long

MINERALS. 



Continue study of fossil animals. Change of structure 

 in earth's crust; erosion, sedimentation, upheaval, denuda- 

 tion. Relate coral and limestone to rock in Michigan.
