The document describes several experiments with light and color. It explains that when a spinning color wheel or disk is viewed, the individual colors cannot be seen and it appears white or gray due to the mixing of the light. Another experiment shows that white light can be split using a prism into the colors of the rainbow. When the rainbow colors pass through a magnifying glass, they converge again and appear as white light.

The document discusses the current state of crops and plants in Marina di Carrara, Italy, noting that olives, plums and cherries are now ripe on the plants, and that potatoes, lavender, rosemary and sage will soon be harvested, while corn is already high and popcorn will be prepared in September, and tomatoes and zucchini are currently growing in the greenhouse.
The document describes establishing an eco-garden in Marina di Carrara, Italy. In the fall, the group decided on a location for the garden and began working the soil and planting potatoes. They also transplanted aromatic herbs like lavender, sage, rosemary and thyme from pots into the ground. The volunteers enjoyed working outside in the garden and learning how to use gardening tools like shovels and rakes, watering the plants at the end of their work.
The school is starting an eco-garden project by fencing off and preparing three plots of land near the greenhouse in the school garden. Over the coming months they will till the soil, plow the ground, seed maize and potatoes, and transplant aromatic plants from the greenhouse to the garden plots.

3. I BUCHI NELL’ ACQUA
Interazione borotalco-sapone
VERSARE DEL BOROTALCO IN UNA BACCINELLA PIENA DI ACQUA
Il borotalco “rimane in superficie” e “non si bagna ”
Le dita rimangono asciutte
Muovendo l ’acqua si muove anche il borotalco
Incredibile!! Le mani restano asciutte!
“ BUCHI NELL’ACQUA”
Adesso le e dita si bagnano
Bagnamo le dite con gocce di sapone
Il borotalco si raggruppa e lascia spazio all’acqua
Togliere con setaccio il borotalco : E ’ rimasto asciutto
Materiale: bacinella – detersivo per piatti – borotalco. Procedimento: Versare
della polvere di borotalco in una bacinella d ’acqua. Versare poi qualche goccia
di sapone nella bacinella. Osservazioni: Dopo aver messo un po' di borotalco
sulla superficie dell'acqua lo si osserva galleggiare. Aggiungendo poi una goccia
di sapone sulla superficie dell'acqua si potrà osservare che il borotalco comincia
ad affondare e, dopo qualche minuto è completamente scomparso dalla superficie
dell'acqua. VARIAZIONE ESPERIMENTO.
HOLES IN WATER
Soap and talcum powder interaction
POUR SOME TALCUM POWDER INTO A BASIN FULL OF WATER
The talcum powder “stays on the surface” and " doesn’t get wet"
Your fingers remain dry
Move water into the basin and you will see the talcum powder moving too!
Incredible!! Your hands are dry!
"HOLES IN THE WATER"
Now get your fingers wet with drops of soap.
The talcum powder will group together and leave space for water
Remove the talcum powder with a sieve: it is dry!
Materials: basin – washing-up liquid - talcum powder. Method: Pour some
talcum powder in a basin full of water. Pour a few drops of soap in the basin.
Observations: after putting a bit of talcum powder on the water surface you can
see it floating Adding a drop of soap on the water surface you can see that the
talcum powder begins to sink and, after a few minutes it will completely
disappear from the water surface. EXPERIMENT VARIATION.

4. L’ARCOBALENO NEL PIATTINO
Seguendo queste istruzioni potrete scoprire gli effetti della tensione superficiale
impiegando del latte colorato.
Materiale necessario
un piattino
latte
colorante alimentare (quattro diversi colori)
detergente
Procedimento
Riempire il piattino con il latte.
Aggiungere una goccia di ciascun colorante alimentare nel latte intorno al bordo
del piattino.
Aggiungere una goccia di detersivo nel centro del piattino.
Cosa succede
I colori si mescolano e si distribuiscono attorno al piattino.
Il latte è tenuto insieme, come tutti i liquidi, a causa della tensione superficiale.
Questa agisce come una membrana e mantiene il latte in una bolla. Quando si
aggiunge il detergente, la membrana si spezza in un unico punto a causa della
diminuzione della tensione superficiale.
La forza di attrazione dovuta alla tensione superficiale del latte a bordo del
piattino fa sì che il latte nel centro si sposti verso l'esterno, assumendo i colori
con essa.
I colori si mantengono in movimento fino a quando il detergente si distrubisce su
tutto il latte
RAINBOW IN A SAUCER
By following these instructions you can discover the effect of the surface
tension.
You need:
-a saucer
-milk
-food colourings (four different colours)
-detergent
Procedure:
1. Fill the saucer with milk.
2. Add a drop of each food coloring in the milk around the side of the saucer.
3. Add a drop of soap in the middle of the saucer.
What happens:
Colours mix together and spread around the saucer.
The milk is kept together, like all other liquids, due to the superficial
tension. This works as a membrane and keeps the milk in a bubble. When you
add the detergent, the membrane breaks in a single point due to the decreased
surface tension.
1
5. The force of attraction, because of the milk surface tension on the rim of saucer,
creates the movement of the milk from the center of the dish outwards, taking
colours with it. Colours keep moving until the detergent spreads all over the
milk.
LE BARCHETTE SULL’ACQUA
Cosa occorre
Alcuni piatti di plastica, forbici, una bacinella rettangolare, acqua pulita, pezzetti
di sapone o sapone liquido.
Come procedere
Ricavare dalla base di un piatto una forma affusolata e praticare un piccolo
incavo nella sua parte terminale.
Disporre la forma nella bacinella piena d’acqua e in corrispondenza dell’incavo
posizionare un pezzo di sapone (oppure lasciare cadere una goccia di sapone
liquido).
La vostra piccola zattera comincerà a muoversi sotto la spinta della tensione
superficiale.
La velocità della zattera dipende fortemente dalla geometria della forma
utilizzata, per verificarlo basta organizzare gare di velocità fra forme diverse, un
rettangolo, una circonferenza, un triangolo.
Ricordare sempre di cambiare l’acqua dopo ogni prova.

6. RAFTS IN WATER
You need:
Some plastic plates, scissors, a rectangular basin, clean water, pieces of soap or
some drops of liquid soap.
Cut off the rim and from the flat part of your plate cut out a tapered shape, then
cut a small slit in its back.
Put the shape into the water-filled basin and place a small piece of soap (or some
drops of liquid soap) in the slit.
Your small raft will begin to sail because of the push of the surface tension.
The speed of your raft depends on the geometry of the shape you chose: if you
want to test that, try a competition between rafts with different shapes
( rectangles, triangles, circles...).
But … remember to change the water in the basin after each
“race”.

7. IL DIAVOLETTO CARTESIO
Materiale per l’esperimento:
- un recipiente piuttosto stretto pieno d’acqua (per esempio una bottiglia di plastica tagliata a ¾);
- una bottiglietta di vetro vuota (vanno benissimo quelle delle essenze o dei medicinali);
- un palloncino;
- un elastico.
Procedimento:
Riempite d’acqua il recipiente per tre quarti. Dopodiché, riempite per metà la bottiglietta e, trattenendo l’acqua con un dito,
immergetela capovolta nel recipiente, la vedrete galleggiare (sarà sufficiente attendere, è essenziale che nella bottiglietta
resti dell’aria e che il collo della bottiglietta sia rivolto verso il basso). Ora sigillate il recipiente con il palloncino (apritelo
con le forbici, se necessario) e con l’elastico, creando una sorta di tappo di gomma.
Adesso premete la superficie del vostro "tappo": vedrete la bottiglietta (il diavoletto) all’interno del recipiente muoversi
verso il basso. Non appena smetterete di applicare pressione, la bottiglietta risalirà in superficie come per magia.
Spiegazione:
il movimento della bottiglietta è strettamente correlato all'aumento di pressione, che determina una variazione del volume
dell’aria all’interno del recipiente. Se si applica pressione, l’aria resta compressa, il suo volume diminuisce e quindi un po’di
acqua può penetrare all'interno della bottiglietta, provocandone l'affondamento. Al contrario, se non si applica pressione, il
volume dell'aria torna quello di partenza, l'acqua "in eccesso" nella bottiglietta defluisce e la bottiglietta torna a galla.
THE LITTLE DESCARTES’ DEVIL
Materials for the experiment:
a narrow container filled with water (if you cut off the top ¼ of a plastic bottle it
would make a good container),
an empty small glass bottle (the ones for perfume or medicine)
a balloon and an elastic band.
Fill your container with water till its ¾ full , then half fill the glass bottle and
close its hole with your finger, dip it upside down into the container ( it is
important that some air remains inside the bottle and that the bottleneck is facing
down).
Now tightly close the container with the balloon (open it using scissors if
necessary ) and with the elastic band making something like a rubber cap.
Now press the surface of the rubber cap: you'll see the small glass bottle (the
small devil!) move downwards inside the container.
As soon as you stop your pressure the glass bottle will come to the surface again
as if by magic!
Explanation:
1
8. The movement of the glass bottle is closely related to the increase of the pressure
which causes a variation in the volume of the air inside the container.
If you apply pressure, the air is compressed and its volume decreases, so a little
bit of water can seep into the glass bottle causing it to sink.
While, if you don't apply a pressure, the volume of the air becomes the same as at
the begining of the experiment, the excess water inside the bottle flows and it
starts to float again.
UN SOMMERGIBILE AD ARIA
You need:
a plastic bottle, plasticine, a plastic tube, a basin filled with water, some coins,
sellotape.
WHAT YOU HAVE TO DO.
•Make 3 or 4 holes on one side of the bottle. Then use some sello tape to fix 3 or
4 coins on the same side ( this is the weight that will let the submarine submerge)
•insert the tube into the upper part of the bottle after having made a hole
•put the submarine inside the basin
•blow into the tube to push some air inside the submarine. While you do that, the
water will be pushed outside through the holes
•when the submarine begins to fill with air, it rises slowly towards the surface.
You can let it surface or go to the bottom by varying the quantity of air inside it
HOW DOES IT WORK?
The weight of air is less than that of water. When you fill your submarine with
air, it becomes lighter than water and it surfaces.
