CHAPTER II 



THE MAKING OF A SUNDIAL OBSERVATIONS UPON CLOUDS 

 NAKED EYE ASTRONOMY 



THE MAKING OF A SUN-DIAL 



SHADOWS cast by the sun under various conditions may be 

 considered still further. Observations of the kind suggested have a 

 bearing upon everyday matters and a connection with geography 

 which should not be overlooked. 



We would suggest the practical construction of a sun- 

 dial as one piece of such work.^ For this it is necessary 

 to find a level surface, and to devise a means of supporting 

 a small rod so that it can be moved at will. A log of wood 

 stood on end (see figure 28) may provide the first, 

 while an empty chip match box and a wooden skewer 

 form convenient material in the 

 second case. 



Pierce a hole with the point of the 

 skewer in the top of the box, near 

 one end, and insert its broader end. 

 If necessary the box may be filled with 

 sand in order to make it more steady. 

 Put the arrangement where the

length of the shadow thrown by your skewer at different times 



*At Queenswood School, Clapham Park, where this observational work has been 

 carried out for some years by Miss Nellie Sweeney, a retort stand is used to form the upright.
