Float a test tube filled with water on a piece of foam in a big bowl of water. Bring strong neodymium magnets near the vertical tube. Do not touch the tube. Water is diamagnetic in nature and will be repelled by the strong magnets. The test tube will move to one side. This simple experiment demonstrates the diamagnetic nature of water.

जब "टीचर" पहली बार 1963 में छपी तो उसे बहुत सराहा गया. सिल्विया एश्टन वार्नर ने "भावनात्मक शब्दों" की पहली बार बात की. छोटे बच्चों की पढ़ाई में उनके पहले शब्द ऐसे हों जिनका उनकी ज़िंदगी से गहरा भावनात्मक लगाव या रिश्ता हो. सिल्विया के अनुसार जो कुछ भी हम पाठ्यक्रम के नाम पर बच्चों पर ऊपर से थोपते हैं उस प्लास्टर की पपड़ियां बहुत जल्दी निकल जाती हैं. उनके एक गरीब आदिवासी स्कूल में छह महीनों में बच्चों ने खुद अपने जीवन के प्रसंगों पर आधारित 60 सचित्र पुस्तकें लिखीं - जो उनकी ज़िंदगी का ताना-बाना थीं. और क्योकि बच्चों ने वो किताबें लिखीं थीं इसलिए वो उन्हें तेज़ी से पढ़ सकते थे. सिल्विया की पद्दति का बाद में ब्राज़ील के क्रांतिकारी शिक्षक पाउलो फ्रेरे ने उपयोग किया. उन्होंने इस तरीके का उपयोग करके किसानों, मज़दूरों और अशिक्षित नवयुवकों को 45 दिनों में लिखना पढ़ना सिखाया.
First published in 1963, TEACHER was immediately acclaimed as a seminal work, one which radically altered the way in which we transmit knowledge to the young. Sylvia Ashton-Warner’s exhilarating and simple concept of Organic Teaching” based on over twenty years of experience, uses a “Key Vocabulary” in which the teacher enters the children’s own experience to help them read and write. Sylvia’s methods were later used extensively by many educators namely the revolutionary educator Paulo Friere from Brazil to teach the landless laborers, unschooled workers, jobless youth to read and write in just 45 days!
The story is about a school TOMOE run by a visionary principal Kobayashi. The school was made of 9 disused railway wagons.

DIVASWAPNA (meaning DAY DREAMING) is the story of an imaginary teacher Laxmishankar who despite the rigid and bureaucratic structure of the school tries to imbue life in it. He soon realizes that Stories went straight to children’s hearts. He does away with boring state text books and with the money thus saved he starts a classroom library. The dream is NOT THE WORD, BUT THE WORLD.
DIVASWAPNA was originally written in Gujarati in 1931. It took almost 60 years to get this iconic book into English. The translation from the original Gujarati was done by Chitranjan Pathak – Gijubhai’s son-in-law after he retired as a principal of a school in Mumbai. The foreword was written by Prof. Krishna Kumar – ex Director of the NCERT.
The National Book Trust (NBT) India has brought out DIVASWAPNA into 11 Indian languages. Here is the link to this book in English.

This wonderful pump is called as a Motor-Pump because it is operated by a small toy motor. You will need a toy motor, battery pack, a film can, flexi-pipes, double sided sticky tape etc. First make three holes in the film can - on the base, lid and the cylindrical surface. Stick double sided sticky tape on the base hole in press fit a flexible pipe in it. This will be the INLET tube. Stick another tape on the cylindrical surface and stick a piece of foam on it. Press fit the OUTLET plastic tube in it. Take a thin aluminum strip and fold it to make a 4-blade star shaped fan. Cut a stiff plastic refill and glue it inside the fan. The refill will be like the bearing. This fan will spin inside the film can and push the water out. Stick another double tape on the hole of the can lid. Then stick a 3-volt toy motor to the tape. You can see the axle of the motor. Press fit the refill of the vane in the motor axle. Attach the motor to a 3-volt battery pack. On switching ON the fan will spin at a high speed. We are slowly getting the elements of the pump in place. Insert the fan in the film can and close the lid. This is the whole assembly of the motor pump. The fan spins when power is switched ON. Finally open the pump and fill the bottle with water. Once the pump is primed insert the fan and shut the lid. On switching the motor the pump will throw large quantities of water. This resembles a real life pump!
This is a very exciting science model using very simple materials. You will need two plastic bottle, stiff straws, rubber glue and cello-tape. Stick two bottle lids back-to-back with rubber glue. Tape the joints to make it strong. Make two small holes in the twin-lids. Insert stiff fruit juice straws 5-cm long in the holes. Fill one bottle to the top with Kerosene. In India Kerosene is colored blue. Fill the other bottle with ordinary tap water. Screw the twin-lid tightly on the Kerosene bottle. Upturn the Kerosene bottle and screw it on the water bottle.
Now invert the bottles so with the Kerosene bottle below and the Water bottle above. See what happens? Kerosene being lighter than water its drops will rise above. Water being heavier than Kerosene its drops will fall below. Slowly you will see a small layer of Kerosene on the top bottle and a layer of water in the lower bottle. It’s a wonderful sight to behold.
Repeat this experiment with cooking oil and water. Cooking oil being lighter its drops will rise up and water drops being heavier will fall below.
This Solar Boat has been designed by LG / Korea and made available to us through the Dept. of Physics, Pune University, India. This is a pre-made kit. The heart is a solar panel attached to a toy motor with a worm gear. The motor spins when the sun shines on the solar panel. Place the motor in its casing. Then assemble the boat body which is made of Styrofoam. These two mounts have a hole where the main axle will come. In the front is the pilot. And this is the mount for the solar panel. This mount enables the solar panel to be tilted so as to catch the sun. Place the motor along the worm gear in place. Also place the solar panel on its mount. Place the axle with the gear in the middle and with two paddles on its ends. This is the entire assembly of the solar boat. The worm gear of the motor rotates the gear on the axle and which spins the paddles. The solar panel angle can be adjusted to face the sun. On placing in the sun the solar panel will provide the current to run the motor which in turn will spin the paddles. When the solar panel is in a shadow no electricity is produced and the motor. Place the solar boat in a big tub of water. In sunlight the boat will go forwards, but in shadow it will stop because the solar panel will not produce any electricity.
You can tie four strings to the top loop of the slinky. Then two children can have a go at it at the same time. They place the thread loops on their index finger and then put them in their ears. On rocking the slinky they will hear the most amazing sounds! The same game can be played by several children at one go.
Now all the children can join hands and you will see that electricity flows through all of them – completing the circuit and making the stick Buzz!
It has many beautiful things in store.
We just need to observe carefully.
Here are the dried pods of the Tattle tree also called the Jungli Badam.
Each pod is a work of art in its own right.
We have simply put our signatures.
Make a baby cone and affix it like a beak to make a ROCKING BIRD.
This bird will easily peck at the seeds on the ground.
Now fix the beak on the tail end to make a different bird.
To make a PARADISE FLYCATCHER simply affix eyes and paint the beak.
With two pods make TWIN TWITTERS.
Fix two tusks and glue eyes to make the Elephant God - LORD GANESHA!

Gift this BOX to a dear friend.
The Peepal Tree is also called as the Bodhi Tree.
It has heart shaped leaves.
Take one leaf and tear it in the middle along the mid-riff.
You can do it with your bare hands without the use of scissors.
This will make the BODY of the cat.
Take another leaf.
Tear along two veins of the leaf and remove a small section on the top.
This will make the two ears of the cat.
Remove the stem at the bottom to complete the FACE of the cat.
Place the FACE and the BODY to make a wonderful cat.
Take more leaves and make the whole cat family.
Make millions and billions and trillions of cats.
Hold the straw in one hand and start cutting a spiral with the other hand.
For this you will need to keep rotating the straw with one hand and cutting with the other.
Keep cutting until you cut the spiral on half the straw.
Now stretch to see the spring like spiral.
Now flatten and cut a pencil point on the other end to make a REED.
Take a spiral straw without the reed.
On blowing the spring will flagellate and vibrate like a baby elephant’s trunk.
Now blow the one with the REED.
This is a two-in-one. You will see the vibrating straw as well hear the flute!
You will need a slipper, sticks, nuts and other odd material.
First fix pivot to the round rubber face.
Attach long sticks as arms to the face.
Fix steel nuts as weights at the end of the arms.
Now place the pivot on a bottle cap.

Then wind insulated copper wire on a sewing machine bobbin. Later scrape the COMPLETE insulation from both the ends. Both arms will be shining copper. When current will flow through the wire the bobbin will become an electromagnet.
Stretch a 1-cm wide rubber band from an old cycle tube on a 1.5-volt torch battery. Insert two long Safety Pins to the Plus and Minus of the battery. Now place the bobbin on the battery and tie its leads to the two pins. Current would start flowing through the bobbin and it will become an electromagnet.
Finally place the coil in the eyes of the Safety Pins. Give the coil a little nudge and it will start to spin. This is a No-magnet motor. Both the spinning coil and the bobbin become electromagnets and their interaction makes the motor work.
If you bring a Ferrite magnet on top, the spinning coil will slow down or Speed up depending upon the polarity of the magnet.
