How easy it is to become mesmerized by modern technology – perhaps by a 3D TV set, or the surround sound of a home theatre system or by the amazing graphics of the latest computer game. We feel life is more complete when we are “plugged in!” We tend to forget that nature has endowed us with a marvelous sensory apparatus – one which technology simply cannot replicate.
Take our eyes for example. Humans have the sight of a predator – stereoscopic vision able perceive objects in three dimensions, gauging both depth and position. With help of special “cones” in the back of our eyes, we are able to discern over 10 million colours! Our ears placed on either side of our head help us to pick up sound vibrations, channeling them through a funnel to the inner ear full of fluid. When the fluid moves, special hairs trigger neural impulses and we perceive sound. We hear frequencies between sixteen and 20,000 cycles per second – sensitive enough to be able detect wind gently moving through grasses and bold enough to be able to take in the roar of a lion. We hear sounds from different locations simultaneously – one could say we hear in 3 dimensions. With every breath in and out, we pick up odours – over 10,000 of them and they are evocative enough to bring back distant childhood memories of a freshly baked pie or the smell of fresh rain. We are enveloped in skin – the barrier between us and the world – and special receptors called Meissner’s corpuscles (in some locations like the finger tips, we have over 9,000 of these per square inch) respond to the slightest pressure, a gentle caress or the sweep of a cool breeze. Crammed in our mouth, like tiny volcanoes our 10,000 taste buds help us to detect the faintest of flavours – for example our tongue can help us detect bitterness in as little as one part per 2 million.
It is our hope that you can encourage your children to occasionally unplug technology and “plug in” to the natural world through the wonder of your senses. In a way – this is our green conduit – the most fundamental and arguably most powerful way to connect our children to nature. To drink the world in through our senses takes practice. Steve Van Matre, a well-known Outdoor Educator, calls activities that promote sensory awareness “acclimatization activities.”
Outdoor Activity
Here are a few ideas to help your kids enhance their senses. Practice at least one of these every time you go outside!
Hearing
Focused Hearing: Take your two hands, squeeze your fingers together and then cup your hands behind your ears. If you can, push your ears out. This simple gesture enhances your hearing by up to 10 times. Try this: Listen to a natural sound in the distance without your hands. Then slip your hands behind your ears as described. You’ll hear a noticeable difference! In a way, your ears have become “deer ears” – large parabolic dishes that capture sound waves. With your “deer ears” on, listen to the wind through the trees, the gurgling of water along a stream, the squelch of mud underfoot. Your hands have focused sound right into your ear. This is a perfect way to begin learning the language of birds and frogs.
Smell
The Nose Knows: Next time you go for a walk, take a long a wet sponge (it may help to cut this up into cubes about 3 cm x 3cm) and several empty cups. Dab a sponge under everyone’s nose. Just a little moisture on the upper lip will suffice. The wetness under your nose helps you to distinguish more odours. Try a little “scratch and sniff.” Gently rub cedar leaves between your hands, or along bark, or among grasses. The act of rubbing releases chemicals that your nose will quickly register as a series of distinctive smells. As you hike, encourage your kids to selectively harvest tiny “bits” of the forest: a small pinch of soil, a part of a leaf, a pedal of a wildflower, a flake of bark. Place these carefully into your cup. Add a small stick as a swivel stick. This is your smell cocktail! Give each creation a name, perhaps “leafatopia” or “forest fragrance.” Can you identify the smells?
Vision
Splatter Vision: When we walk in a natural setting, chances are our eyes are cast down. Makes sense, for our inclination is not to stumble. However, by focusing only on our feet as we move through nature; we are missing so much of what is going on behind, above and to the sides of us. Practice being an “all around watcher” and use what naturalists call “splatter vision.” This means not keeping your eyes in one place for too long. As you walk, glance up, glance to the sides, glance in the distance, glance up close. By continuously sweeping your eyes around, you are more likely to pick up movement in the landscape – perhaps a cotton tail rabbit huddled under a bush, an owl perched in a tree or a deer frozen on a hill side. Some of my most amazing discoveries have been out of the corner of my eye. Walk in silence and practice splatter vision. Take the time to recount your discoveries!
Taste
Forest Tea: The healthiest food, argues Wendell Berry, is the shortest distance from the earth to your mouth. Introduce kids to the edible wild and the wonder of tasting gifts from the landscape. You need to be careful however. Please make the point that kids should only eat what an adult knows for certain is safe to eat. Stay away from berries. As you walk, harvest a handful of eastern white cedar (the needles look a bit like feathers) and white pine (long soft needles in bunches of 5). When you get home, toss these in boiling water and let steep for at least 10 minutes. The resulting tea will be bitter but refreshing and your tongue will dance with a pungent but evocative taste of the forest!
Touch
My Personal Friend: This is a wonderful activity connecting touch with sight. It works best in open park land or school yard with lots of trees. You’ll need one blindfold for every two people. To demonstrate the activity, blindfold one volunteer. Tell them that you are going to introduce them to a special friend. Gently walk with them, avoiding bumping into obstacles (they are blindfolded!) in a circuitous route, avoiding a straight line. Select a tree. Preferably one that isn’t too big. Have them feel the texture of the bark, the arrangement of branches on the limbs, the shape of the leaves, the veining pattern on the underside of leaves, the girth of trunk, the proximity of neighbours. The more tactile clues you offer, the better. Now take them back (but not the same way!). Gently spin them once or twice and then remove the blindfold. Can they find their tree? Often this is easier said than done. Switch partners.
