NATURE-STUDY WITH ASTRONOMY 



In childhood we should be taught something of the wonders 

 of the Universe. 



The Sun — What it is — how it looks — its explosiveness — its 

 corona — its size — its weight. 



Sun Spots — their .movements — the rotation of the sun. 



The Sun's family — the plane of their rotation — what is a 

 year? 



The size and year length of Mercury — Venus — Earth — 

 Mars — Jupiter — Saturn — Uranus — Neptune — The moons of 

 the planets. 



The relation of the sun to the earth : What the heat of the 

 sun does for us. How the atmosphere tempers the heat. 



Variation in time of rising and setting sun — why? 



The longest and shortest day of the year — why? 



The shadow stick and what it demonstrates : 



The seasons, the equinox, solstice. What an eclipse is. 



How to make a sun dial. 



Uncle John's story. 



Comets, meteors, or shooting stars. 



The Moon — What it is. Shines by reflected light. 



If the whole firmament were packed with full moons we 

 should receive from them all less than one-eighth the sun's 

 light. 



What a moon is. The reasons for the difference in time 

 of the rising and setting of the moon. 



The reasons for the moon's phases. 



The length of the moon; days and night. 



The topography of the moon : High jagged mountains, 

 30,000 ft. high. The craters — 33,000 discovered and map- 

 ped. Plains and chasms. The colors of the rocks. The 

 force of gravity — one-sixth that of the earth. 



The effect upon the moon of lack of atmosphere: no life, 

 no water, no clouds, sky black, stars invisible always, shadows 

 black, temperature of day and night, effect on rocks, no 

 sound, no protection from meteorites. 



The value of a study of the moon's condition in teaching 

 physical geography.
