Tadpole and Fish Fable of Comprehension
Michael Dickmann: Here's what the story is. There was this little tadpole and a fish that grew up in a pond, and they were always intensely curious about life outside the pond.

the birdwatcher, the attention to minute detail of the
entomologist, the courage of the herpetologist wading
into swamps full of poisonous snakes. But some “field
skills” are nearly ubiquitous. Perhaps the most

one rare gull on a pond among seven hundred
common ones may have to watch for hours in bi...Without them the naturalist would miss the rarities in nature.

Teaching Children Science by Drawing Nature
The British and Irish emphasis on drawing from nature (which has lessened in those places, too) helped develop powers of observation and reinforced curiosity about the natural world. A child who has watched whirligigs and water striders on the surface of a stream will appreciate the importance of clean water. A child who has observed the clouds, their heapings and tumblings, their dark massings and silver linings, will be better prepared to understand the relationship between cloud cover and ...American schoolchildren aren't pushed to draw and immerse themselves in nature; therefore, they don't get the appreciation for it and desire for biodiversity.
