Geddes view of technology and natural education and CIVICS

"In Nature's infinite book of mystery I can a little read."

Patrick Geddes, Outlook tower guide

Man lives by deeds not knowledge. His knowledge is to help him to act: he does not live to know but knows to enable him to live a richer and fuller life.

Comments written on Outlook tower guidebook

‘Vivendo Discimus’ by living we learn inscribed on Riddlers Court Archway, Edinburgh.

Dates back to 1889 when Geddes started Edinburgh university summer schools.

Geddes Evolution of Education:

education was not to be seen as one of his manifold activities, because for Geddes education was “the activity” that would move forward the Ascent of Man towards a better future.

Geddes was sure that human potential could be improved through education, therefore education was the key to rise quality of life in the future.

Geddes saw that new technology would bring about rapid development.

He was not anti-technology as such, but he foresaw that technology would give us the means to kill and pollute our natural environment on an ever greater scale than before.

In order to avoid the inevitable doom, he devoted his life to try to see a way forward to a new cultural era. He had to go on hoping that the environment could be controlled by conscious and well informed choices made by informed individuals.

His quest for a new kind of evolutionary education and the nature of knowledge therefore became first priority.

He went back to first principles about how people learn(how do people learn?) and about what methods are most appropriate. His motto “Vivendo Discimus” or “By Living We Learn” was meant to be a spur for action, there was no end to this search.

The main reason for organising his famous Summer Meetings in Edinburgh, indeed some of them inRiddle’s Court, was to test his ideas and methods on real people hoping to

help participants understand more about themselves and their environment.

because of his objectivity and creativity, he tried to

create a new subject which he called “Civics”.

This was a discipline directed both towards reclaiming human individual creativity and the improvement of the environment.

In some of his thinking machines he tried to plot the interaction between the structure and the process in a system of education. In his model he included the feelings, the thoughts and the experience of individuals because it is

feelings

and sense

and thought

which are important in realising creativity.

It was as far away from any formal school than you can ever imagine.

The objective was not to train in some skill or other and get a piece of paper or certificate at the end of it.

This was education where the students could choose their own courses and preferences freely, or change them every day if they so desired. This kind of freedom would be unthinkable for the rigid programmes of formal education.

Geddes, in his Summer meetings, prepared a magnificent banquet of lectures, visits excursions, concerts and practical work and invited people to tuck in and enjoy it. After all this was holiday time.

Model for new Patrick Geddes Centre for evolutionary education

Produced by Sofia G.Leonard

(very similar to my work!!)

The vision is to establish in Riddles Court a world class learning Centre to contribute to the creation of a learning society promoting active, critical citizenship informed by a twenty-first century dialogue around the principles of the Geddes’ evolutionary education.

Hollow Globe (Episcope) sold at outlook tower

Hollow Globe sold at the Outlook Tower and intended for the teaching of geography.

The brilliant principle of this concave globe was to make cartographic and perspective projection coincide. The geometric construction of the globe was stereographic, i.e. the projection was centred on the surface of the globe. The point chosen was Edinburgh, coinciding exactly with the location where the map was to be seen, so the Episcope presented visitors with what they would have seen if their vision had been capable of stretching across the surface of the earth to countries and continents hidden beyond the horizon. In short, it was a kind of panoramic mappa mundi.

Wyld's Great Globe(giant hollow globe)

an attraction situated in London'sLeicester Square between 1851 and 1862, constructed byJames Wyld (1812–1887), a distinguished mapmaker and former Member of Parliament for Bodmin.

At the centre of a purpose-built hall was a giant globe, 60 feet 4 inches (18.39 m) in diameter. The globe was hollow and contained a staircase and elevated platforms which members of the public could climb in order to view the surface of the earth on its interior surface, which was modelled in plaster of Paris, complete with mountain ranges and rivers all to scale.Punch described the attraction as "a geographical globule which the mind can take in at one swallow."^[1] In the surrounding galleries were displays of Wyld's maps, globes and surveying equipment.

Krstyna Pojerova terrarium and pendant lamp

hanging terrarium also doubles as a pendant lamp, adding both light and life to any room.

The terrarium lamp is made from an onion shaped glass orb. Rather than just an access hole to change the light bulb, the bottom of the glass inverts inside, forming a protective lip around the opening. This holds all the goodies inside, and provides the perfect amount of space to support a new mini garden! Through the opening, you can cultivate your fresh herbs, pick small flowers, or simply water the little green plants.

The lamp portion shines down on your little garden, supporting photosynthesis even in dim spaces, and the excess heat produced by the bulb incubates your fresh herbs, keeping them happy and healthy. There’s also plenty of room to water your plants, and also room for soil. Holes on the top of the orb allow healthy plants to sprout through — but they may need a little guidance.

The Glasshouse was created to foster the urban kitchen, and let city dwellers with no outdoor or window space grow their own fare in a unique way. Aside from adding life to a room, the hanging lamp adds a punch of color and a beautiful design.

The Glasshouse can be ordered from the Czech site Art-Light.

Examining sprouting in a jar

Plant seeds can easily be grown outside of soil so that they can be examined while sprouting. Line a glass jar with a piece of paper towel so that the edge of the towel touches the bottom of the jar. Dampen the towel and put a little water in the bottom of the jar. Put a few beans or corn seeds between the paper and the glass, about halfway down. The paper should hold them in place. Keep the paper moist but not soggy. Place the jar in a sunny location. In a few days the seeds will sprout, first sending roots downward, followed by stems above. The beans are dicots, meaning they will sprout with two little seed leaves. The corn is a monocot and sprouts with a single blade. Early in their growth, the seedlings use the food stored in the seed. Eventually, they will need to be planted in soil so that they will have minerals for growth.

You can also do this by layering a piece of paper towel between two small pieces of glass. The towel, which is the same size as the glass, is placed on the first piece of glass. It is then dampened and a few small seeds, such as radish seeds, are placed on it. The second sheet is placed on top and the whole thing is secured with string or rubber bands. It is then placed in a shallow pan and held upright by lashing it with pieces of string. Add a little water to the pan, which will keep the paper towel moist. Eventually the seeds will sprout. If the glass is turned a quarter of the way around after the roots are somewhat established, they will bend to grow towards the water. No matter how you turn the glass, the roots will grow downward.

Growing plants from food seeds and tubers

Many fruit and vegetable seeds, such as orange, grapefruit, apple, lemon or tomato seeds, can easily be sprouted indoors. Plant them in small pots filled with good garden soil. The seeds should be planted about twice as deep as they are wide. They will sprout at different rates depending on the seed, the citrus fruits usually taking the longest. Avocado pits can be sprouted by sticking toothpicks in the side to form a support that will hold it in the top of a glass or jar filled with water. The wide end of the seed should be just submerged in the water - this is the end where the root will emerge. Keep the glass filled with water and before too long you will have a plant that can be transplanted to a flowerpot. Cuttings from potatoes and sweet potatoes can be grown in a similar way. Make sure your cutting has at least one "eye", which is where the potato vine will grow. The eye needs to be out of the water. Carrot tops will also grow this way if the root end is kept submerged. All of these plants need to be transplanted to soil eventually, as water alone will not supply nutrients for the plant to continue to grow.

Moss terrarium

Mosses can be grown in terrariums fairly easily. Collect moss from an area where it is okay to do so and transport in plastic sandwich bags. Sprinkle with water and seal the bag if you won't be setting up the terrarium right away. Use a large, clean glass jar with a tight fitting lid. Lay it on its side in a shallow box or on a stand so that it will not roll. Place sand and pebbles about ½ inch thick in the bottom of the jar. On top of this place some of the soil from the same place where the moss will be collected, or mix a soil of charcoal, light gravel, leaf mold and garden soil. The soil should be level with the opening of the jar. A little sulfur scattered on the soil will help to prevent mold from growing. Plant the moss by pressing it into the soil. Water the terrarium, screw the cover on, and place it in a shady place. If it seems too wet, leave the lid off for a few hours to allow some of the water vapor to escape. Eventually you will get the balance of water just right, and the moss should thrive. The terrarium should sustain itself for several weeks or months without needing additional water if the lid is kept tightly on. If conditions are just right, the moss may eventually send up little stalks. Some of these stalks form spores that will fall to the soil and germinate into new plants.

Lichens

Lichens grow on rocks, in poor soil, and other places where many plants cannot grow. They are a symbiotic combination of two organisms: a fungus, which anchors the plant and collects water, and an algae, which is a green plant that provides food. They often grow on rocks and are part of the erosion process, slowly breaking the rock down into soil. Lichens can be collected for terrariums. Keep in mind that some species of lichen are endangered and protected by law, so be sure it is okay to harvest a particular species from wherever you have found it. Once collected, place in a terrarium with a soil of 1 part loam, 1 part sand, and 2 parts humus. Add a few twigs and small rocks. Water, but don't over water or mold may form. Seal with a tight fitting lid and place in a sunny but cool location. Usually, even dry lichens that appear dead will soon thrive in the humid terrarium.

Mold garden

Mold is a fungus and relies on whatever it is growing on for nutrients. It grows from spores, which float through the air and begin to grow when they land on a good source of food in a warm, damp place. You easily grow certain varieties for study on a piece of bread. Sprinkle a piece of bread with water, and let it stand for about an hour. Place it in a jar and screw the lid on tightly. Put the jar in a warm, dark place. In two or three days the bread should be covered with white cottony material and small black dots. This is common bread mold. Any other colors seen are from other varieties of mold. If you look at it under a magnifying glass or low power microscope, you will see that the white material is actually threadlike. This is the mycelium, and is the same structure as the "root" of a mushroom (not a true root). Some of the mycelium branches upward, ending in sporangia, or spore cases, containing many spores that will eventually burst free and float away to form new plants. Discard the bread after examining.

Yeast is also a fungus, and gives off carbon dioxide as it grows. This carbon dioxide is what gives lightness to yeast breads and bubbles (and alcohol) to beer. If you put a little baking yeast into a cup of sugar water and let stand in a warm place for a few minutes, you should be able to see the yeast plants budding to from new plants.

Plant lore

The colored water and celery trick

Water normally enters a plant through its roots. It is carried upwards to all parts of the plant by means by capillary action. You can make the tubes that carry water through a plant easier to see with a class of water that has been dyed with food coloring. Set a whole carrot (without its green top) in a glass of water dyes with food coloring - red works the best. Let the carrot sit overnight. Remove it from the glass, and slice off a section from the top. Slice the bottom part lengthwise and you can easily see where the water has flowed. The tubes that carry the water, by the way, are called xylem.

This is much more dramatic with a celery stalk. Place the stalk (with leaves) in the dyed water for three hours or so. The water will be carried up through the stalk and out to the leaves, which will be dyed. If another stalk is partly split in half from the bottom, and each half is placed in a different color of water (red and blue, perhaps), then each half will be colored a different shade. The same thing can be done with a white carnation.

Chlorophyll

Green plants are green because of chlorophyll, which is the chemical responsible for photosynthesis of the plant's food. During the daylight, the plant takes in carbon dioxide, water, and minerals from the ground and air. The chlorophyll, housed in individual cells within tiny bodies called chloroplasts, enables the plant to make sugar (glucose) with the raw materials it takes in, using sunlight as energy. The byproduct is oxygen, which is expelled through tiny openings called stomata, located in the bottoms of the leaves. You can see this oxygen bubbling off water plants in an aquarium. The glucose is stored in the leaves as starch.

If a plant, or part of a plant, is grown totally without sunlight, chlorophyll will not develop. Cover half of a leaf (still attached to the plant) with black paper (geraniums work well for this). Put the plant in sunlight for 48 hours. Remove the black paper and one half of the leaf should be yellowish. Chlorophyll will break down if it does not receive sunlight for an extended period of time. The base color of many leaves is yellow, which is why some leaves turn yellow in the autumn; the other fall colors are due to chemical changes within the leaves. Remove the leaf from the plant and soak it in warm alcohol until the chlorophyll has been removed from it. If the leaf is now dipped in iodine solution, the part that has received sunlight will turn blue, as iodine turns blue in the presence of starch.

Bleaching flowers to show chlorophyll

Tie several different colored flowers together at the stems. Place a little ammonia in the bottom of a large jar. Suspend the flowers from the top of the jar either by passing the string through a plastic lid that fits the jar or by attaching a strip of wood, wire, etc. across the mouth of the jar that the flowers can be hung from and sealing with plastic wrap. The flowers should not touch the ammonia. In a few minutes, the colors will fade from some of the flowers, especially any reds, purples, or pinks (not so much with white or yellow). The petals of some of the flowers will appear greenish due to the chlorophyll within.

Preserving plants

Pressed plants

Leaves, stems and flowers that are not too thick are best for pressing. Always make certain that you are not picking leaves or flowers from species that are protected. To make a press, start with two thin but sturdy pieces of wood that are larger than the plants you will be pressing. On the bottom of one, nail two leather straps or old belts. Or you can simply use two pieces of light rope to bind the press together. Layer sheets of cardboard and newspaper between the wooden boards. Place the plants between the newspaper sheets, binding the whole thing together each time you do so. Whenever known, make a note of the type of plant when it is collected. If you only have a few plants to press, you can do so simply by placing them between sheets of newspaper and weighting them for a few days. It is best to change the newspapers each day until the plant is thoroughly dry. You can display the dried and labeled plants on a sheet of heavy paper by gluing or taping them down (spots of rubber cement work well), or you can laminate them between plastic, which will keep insects away from them.

Preserving leaves with glycerin

Some of the more stout leaves, such as holly, magnolia, and some of the maples, can be preserved without flattening them by using glycerin, which is still readily available in many pharmacies. By trial and error you can determine which types of leaves work best by this method. The leaves used should be very fresh. Add 2 parts boiling water to 1 part glycerin. Place the leaf in the warm glycerin solution so that its petiole (stem) is submerged 3-4 inches (7-10 cm). How long the process takes depends on the type of leaf, but you will know enough has been absorbed when drops of glycerin appear on the surface of the leaf. Remove the leaf from the solution and wipe to remove any excess. Drain on thick stacks of newspaper for a few days, then wash (not too rough!) with a little soap and water. Hang on a line (wooden clothespins are useful here) to dry.

You can capture fall colors in leaves fairly well using this method. Pick the leaves just as they are turning. If they have completely turned or have fallen from the tree they probably won't absorb much of the glycerin solution. You can also preserve branches (twiglets and leaves) fairly well, but it will require quite a bit of glycerin, so it may be cost prohibitive. If you do want to try a small branch, the entire thing needs to be immersed in a warm solution of 1 part glycerin to 1 part water. Leave it in for at least double the time that it takes for one leaf from the same plant to complete using the single leaf method.

Drying flowers

To preserve the shape of flowers, pour an inch or so of borax into the bottom of a small cardboard box. Sturdy flowers work best for this. Set the cut flowers, stem side down, into the borax. Slowly and carefully cover the flowers with more borax, and set the box in a sunny place for 2 or 3 weeks (delicate flowers dry faster - a week or so). Carefully pour off the borax and save for the next drying. The flowers will be fragile, but the shape and much of the color should be preserved. Fine white sand can be substituted if borax can't be found.

Leaf prints

Leaf prints are a good way of making a record of the size and shapes of leaves of various trees. First, collect a leaf or two from a specific tree. Identify the tree whenever possible and not this with the leaves. The leaves chosen should be as free from holes and tears as possible. It is better (for the tree anyway) if you can find good leaves that have fallen from the tree. Place the leaves in a press (several thickness of newspapers topped with a weight) to flatten. This should only take a day or two, depending on the thickness of the leaf. Prepare a workspace by covering a table with newspapers. Pour some colored ink into a small dish, and dip an old toothbrush into the ink. Practice making spatters by scraping a short stick toward you (not away) through the bristles. This causes the ink to spatter away from you. You can also run the toothbrush over a fine mesh screen held over the leaf. Practice until you can get a fine, controlled spatter. Place the leaf onto a piece of art paper and spatter around the edges of the leaf.

Smoke prints

Cover the side of a smooth, round bottle with a thin layer of grease or Vaseline. Fill it with cold water and cap tightly. Hold it over a candle flame, spinning it, until it is covered with an even layer of soot. Place a leaf, vein side up, on a piece of newspaper. Roll the soot-covered bottle over the leaf, then move the leaf to a clean newspaper, soot side up. Cover it with a sheet of white paper and roll with a clean bottle or rubber roller. You can make the print smudge resistant by spraying it with an artist's fixative coating.

Leaf skeletons

You can "skeletonize" a fresh leaf, green to expose the lacy pattern of veins it uses to transport food. Make a beating board by tacking an old piece of carpet or a thick rag to a board. Use an old shoe brush or hairbrush. The type of brush chosen is very important. It should be fairly fine but not stiff. Most synthetic brushes are too harsh. Once an appropriate brush has been located, place the leaf, top side up, on the beating board. Hold the leaf firmly in place and tap lightly until all of the fleshy part is gone. Occasionally, you will need to turn the leaf to the back side to tap it with the brush. Once the leaf has been skeletonized, you can display it in a scrapbook by gluing it to a piece of paper with a few small dabs of glue. Cover with cellophane. A nicer display can be made by sandwiching the leaf "skeleton" between two same-size pieces of glass sealed at the edges with adhesive tape.

Spore prints

Mushrooms are a fungus and have no chlorophyll. They must get their food from whatever they are growing on. They also have no seeds, and reproduce by means of spores. The spores of a mushroom are located in the gills under the cap. You can make a print of the mushroom using its spores. Each print will be unique to the species of mushroom. Remember when handling mushrooms that many of them are poisonous and some can make you very sick or even kill you if you eat even a tiny bit. Unless you are an expert never eat any mushrooms you find in the wild. Wash your hands after handling any wild mushroom. To make a print, first choose a mushroom with an open cap and exposed gills. Ordinary grocery store variety mushrooms work fine. It should be fairly fresh. Identify the mushroom using a field guide if you are able so that you can label the print later. Remove the cap from the stem. Choose an appropriate piece of paper; dark paper if the spores are light, and light paper they are dark. Place the cap on the paper, gills down. Cover it with a dish so that the spores will not be carried away by air currents and leave it overnight. When the cap is removed, there will be a spore print on the paper.

To make the print more permanent, The paper will need to be covered with a thin coating of gum arabic, which is available from most art supply stores. Spread this thinly over the paper. Three toothpicks will need to be pushed through the mushroom cap so that it sits, tripod style, just barely above the paper. Mucilage can be substituted for the gum arabic if it is allowed to nearly dry, but it does not work quite as well. Egg whites will also work if spread thinly.

Making your own fake shrunken head

There are several ways to model a shrunken head. For example, you can craft a nice little replica if you are handy with papier-mache. Or you can do it the classic way, using an apple. This isn't the most realistic version, but it will make a nice little gnarled head, and has the advantage of actually shrinking in the process, adding a random factor to the creation. In the 1960's, there was a kit sold, featuring actor Vincent Price, that provided hair, beads, feathers, etc. to use with apples to make shrunken heads.
