Nature-study consists of simple, truthful observations that may, like beads on a string, finally be threaded upon the understanding and thus held together as a logical and harmonious whole. Therefore, the object of the nature-study teacher should be to cultivate in the children powers of accurate observation and to build up within them understanding.
WHAT NATURE-STUDY SHOULD DO FOR THE CHILD
First, but not most important, nature-study gives the child practical and helpful knowledge. It makes him familiar with nature’s ways and forces, so that he is not so helpless in the presence of natural misfortune and disasters.
Nature-study cultivates the child’s imagination, since there are so many wonderful and true stories that he may read with his own eyes, which affect his imagination as much as does fairy lore; at the same time nature-study cultivates in him a perception and a regard for what is true, and the power to express it…. Nature-study aids both in discernment and in expression of things as they are.
Nature study cultivates appreciation for beauty and design.
But, more than all, nature-study gives the child a sense of companionship with life out-of-doors and an abiding love of nature. Let this latter be the teacher’s criterion for judging his or her work. If nature-study as taught does not make the child love nature and the out-of-doors,
then it should cease. Let us not inflict permanent injury on the child by turning him away from nature instead of toward it. However, if the love of nature is in the teacher’s heart, there is no danger; such a teacher, no matter by what method, takes the child gently by the hand and walks with him in paths that lead to the seeing and comprehending of what he
may find beneath his feet or above his head. And these paths, whether they lead among the lowliest plants, or whether to the stars, finally converge and bring the wanderer to that serene peace and hopeful faith that is the sure inheritance of all those who realize fully that they are working units of this wonderful universe.
NATURE-STUDY AS A HELP TO HEALTH
Perhaps the most valuable practical lesson the child gets from nature-study is a personal knowledge that nature’s laws are not to be evaded. Wherever he looks, he discovers that attempts at such evasion result in suffering and death. A knowledge thus naturally attained of the immutability of nature’s “must” and “shall not” is in itself a moral education. The realization that the fool as well as the transgressor fares ill in breaking natural laws makes for wisdom in morals as well as in hygiene.
Out-of-door life takes the child afield and keeps him in the open air, which not only helps him physically and occupies his mind with sane subjects, but keeps him out of mischief. It is not only during
childhood that this is true, for love of nature counts much for sanity in later life.
This is an age of nerve tension, and the relaxation which comes from the comforting companionship found in woods and fields is, without doubt, the best remedy for this condition. )there is plenty of research available toay showing that time in nature reduces stress, clears the mind, etc).
