When I was a child, my friends and I used to spend hours chatting and absent-mindedly picking up a handful of soil and letting it filter through our fingers and back to the ground. Over and over again, we allowed ourselves the idle sensuality of feeling loam flow over our fingers. It was a beautiful rich sensation, as if velvet has been crumbled.
Now I know that there was a universe of life, hundreds and thousands of tiny creatures in each handful. It has been estimated that the number of creatures in a single acre of healthy soil exceeds that of all the people living today so, more than 6 billion. In an acre! Some of those microscopic creatures we hardly know anything about and there are some that we understand quite well. Perhaps my scooping hand went near one of the many larger creatures that make their home underground, such as a toad or a mole or a snake.
In truth, most of those millions who live in the earth live between the soils, in tunnels and air pockets, burrows and dens. Even the smallest creatures live in tiny spaces between the soils. All of them, even those deep down, have their responses to the seasons. They will rise toward warmth, go back down to cooler regions when the surface is too hot, rise for for food, go back down again when the surface freezes and it is comparatively warmer below. When the rains come, they may drown by the millions, as their tunnels and pockets are filled with water. If the soil is covered with concrete or tarmac, seasons, water and air are cut off and they all die.
In some parts of the northern hemisphere, farmers refer to the soil as "sleeping" during the winter, when it seems less alive. They speak of the earth "awakening" in the spring, when it warms and the life comes closer to the surface. When every creature in it has been killed and nothing can grow in it, they say the soil has "died". Children need to know this feeling of soil that is healthy and alive, soil that is sleeping or awakening. If you have a place where they can garden, allow them the extra time to play with the soil, to learn its feel. Help them to try to find some of the creatures that live in it.
Soil on the Nature Table
For the hyperactive in your group, by all means, invest in an ant farm to sit on the nature table. From the garden supply shop, get a small amount of composting worms to keep on the table and feed and discuss. Even the squirmiest child will stop his or her own squirming to watch these creatures' movements.
For a Craft activity - have the children draw worms and cut them out. Place a bit of brown felt shaped into mounds like the earth on the nature table and place the children's worms under the mounds. Move the insects toward the surface on warmer days.
Some books about the soil and its creatures:
Life in the SoilThis is a serious read, and a bit heavy in places, but excellent for a full understanding of the latest knowledge about what creatures live in the ground.
Living Earth
This is an older book, and an easier read. It is still quite useful as a basic starter on the subject.
Life in a Bucket of SoilThis is a Dover book, clean, simple and clear, with good drawings. An older child could read it on his or her own.
A children's non-fiction book, with photographs of microscopic animals, drawings, and a lively layout.
Let's Look at Animals Underground
A gimmicky book that actually works very, very well. Illustrations and text on white pages explain the animals that live underground. See-through pages backed by black allow for a child to use a special "torch" to see the underground world.
This is a book from the 1960s, and its geography is North American, but it has clear explanations and some very fun experiments.
