Inauguration of clay room

Roof:

The Roof was built with slabs that were attached together with bindings, and sealed off with some material that had become torn and corroded. Thus making rain water seep in. The solution was covering the cracks with tar sheets. Naveen had got the excess sheets from the repair works at Aura Auro Design’s Lab. He also got a Flame thrower that was antique 😉 (We along with the children had a time figuring out how to light it up) It was a manual tool we had to compress air and it would send out a mixture of kerosene and air that would burn. eventually 🙂 . The children started to measure and cut out the tar sheets from a roll. Naveen  and the children placed the sheets and heated them to stick on the roof with the flame thrower.

We hope this will prevent rain water from seeping in. The roof was then painted with a bright yellow oil paint. We bought 6 liters of oil paint. Children started painting during their sleepover. It took two evenings to paint 2 coat of painting on the roof.

Inside:

The room was now ready to be inaugurated on Sri Aurobindo’s birthday. We had as our chief guest, Swami Sarvasahananda from Ramakrishna Mission, Chengalpattu. He graced our space with his blessings, talk and music. That morning the school was abuzz with activity. Children had stayed over the previous night to participate in the dawnfire meditation. When we came from there, we were working on decorating the clay room. Garlands were made, photos of Sri Aurobindo, Mother, Sri Ramakrishna, Sarada Devi and Swami Vivekananda were decorated. Lamps were kept ready for the opening. Children with help from their teachers got the PA system ready. The harmonium and tabla were arranged. Gopal from Mantra pottery joined us that morning to do clay work. It was a session that children and adults enjoyed. The Swamiji lit the lamp and invited the teachers to do the same. Once the lamps were lit, we all connected with the Divine Mother through songs that the Swamiji and children sang. For those who could remember how forlorn the room had been, it was touching to see how the same little room was shining with all of us invoking the Divine.

As one of the facilitators in creating our clay room, I witnessed the transformation of a space we had neglected over the years into a bright space that we look at every day. That we can transform our environment with one-pointed concentration, team-work, openness to learn, consecration of our work to the Divine are learnings that will stay with us and reveal themselves to us as and when we are ready to understand them.

When I was working with the children in the clay room I learnt to be patient. Involved all the children and gave equal opportunities to all the children. Learnt team work from the children. I saw sharing and caring from the children while working as a team for my self and for others.

(x + y + z)^3 Visualisation

Naveen and I were trying to visualise (x + y + z)^3 with Lavanya a 9th grader in Udavi using the Montessori Cube.

We are able to formulate (x + y + z)^3 = x^3 + y^3 +z^3 + 3x^2y + 3x^2z + 3y^2x + 3y^2z + 3z^2x + 3z^2y + 6xyz

Quadcopter Quadcopter

In STEM Land 9th std children were very eager to do the Quad copter. They wanted to do something different which inspires themselves as well others. We are building an i-smart class room and the 9th std children wanted to paint the room themselves so they stayed the night at the school and painted the room. After the painting they saw a Movie called October sky. By seeing the Movie children got inspired and first thought of building a rocket, but then settled down to build the quadcopter. They felt that since they are in 9th std and would be busy next year with the board examinations they should make full use of STEM Land this year and do something interesting. They thought of it and came up with an idea of making a Quadcopter. They started researching online and looking at videos and worked out the parts they needed to build a quadcopter.They took a DVD and carefully cut it with equal sides and placed the RF control receiver board, four motors and their propellers on it and soldered them. Children used the Big shot camera battery from STEM Land and connected it to the receiver. While connecting the battery and the receiver a pin broke.They traced the pins and soldered connectors and fixed the problem. They figured out to connect the transmitter with the receiver by keeping the transmitter and the receiver so close to each other and pressed the button and waited for few seconds and connected it. They were so happy and eager to finish it and were working on it even during their break. They have almost completed assembling the Quadcopter and now they are working on it to make it fly. Currently it hovers a few cm from the ground before loosing contact with the transmitter. The 8th and 7th children were also looking at it enthusiastically and enjoyed.

Clay room

Painting Outside:

Third graders took responsibility to paint outside. This being a room for clay and woodwork, we wanted to paint it with a natural brownish red-soil color. We inquired with a few painters and once they understood our idea, they all suggested extracting the color from red-soil and binding it with Fevicol. Children in 5,6 and 7 stay over in school on Wednesdays. One Thursday morning, we went with pands and mumpties and collected red soil.

Once the soil was on hand, the third graders sieved it. Water was added to the soil and mixed well. This had to be filtered to extract the color. For the filter, we used some of the cloth bags we receive in grocery stores that don’t use plastic any more. We tool 4 liters of the red-soil water and mixed it with 2 liter of Fevicol. Fevicol made the paint thick. We painted the wall and as it dried up, the wall looked beautiful with hues of orange, red and yellow. We wanted a darker shade since we planned to paint patterns on the wall inspired by Warli art. So for the next coat, we added some brown water color that was on hand. A lovely dark shade was the result. The room is hexagonal giving us six panels to paint on. Over a few evenings after school, teachers and students painted patterns on the wall. We have a panel with a tree and a deer on a full moon night. One more with the Matrimandir, Banyan tree and children visiting there. Some of the paintings did not come well and we painted over them to create a fresh new wall to paint over.

Wooden Torch in Isai STEM land

In Isai Ambalam school children waned to make different types of lights to use it during sleep over. It took 2 to 3 weeks  to build a nice wooden torch. So they started cutting the bamboo during STEM land period. Once they cut the bamboo they  started to build the circuit on a bread board and then started soldering  with wires. Then they made hole in the bamboo with a drill to fix a switch. Then for the front part they really wanted to use some cone shape and to fix the LED. At first they use a waste water bottle. They cut the bottle and took the cone shape but it didn’t last for long time. It also didn’t look good. Then they were struggling with chart paper to make a head for the torch. Then students got some ideas like that what all can be made with bamboo. Some wanted to build a study lamp. These things were made  4th and 5th grades. Three girls thought it is very difficult to build a torch. When some students started to build a study lamp these girls got inspired and they also started to build a torch. When they finish making the torch Monica came to visit STEM land they presented this torch to her. Monica gave a beautiful words for those kids. I also added a image with the words from Monica.                                         

Multiplication with the 5th graders

We started the Vaughn cube Videos, after completing a few lessons the children took up specific multiplication tables and drew all the objects that they could remember. Multiplication become easier for Pranav who could link objects to sounds and then to numbers.

Rain maker

In Udavi, Students have activity class once in a week and some of the children choose STEM land as an activity class. Last Friday we had activity class with 7th and 8th graders. Children wanted to do very interesting project so they thought of a problem that they face in the school. They have gardens in the school and they water the garden daily. But during the holidays one of them had to come the school and water their garden. So they came up with an idea of watering the garden automatically came up with an idea of making a rain maker for their gardens. We learned how a relay works and also about the water solenoid valve. We tested the valves that we had in STEM Land by connecting it to a 12V battery and connected the valve to a water pipe and tested it. Luckily all three valves worked. Then we connected it to the Arduino and programmed a simple blinking program and tested by changing its delay. This Friday we learned to charge the 12V battery using the solar panel and we measured the current that we get from the solar panel. when there was bright sun we got around 0.41 A. Next week children will solder the circuit on the PCB and will implement it on the garden.

Automating the bore well motor.

We had a serious  water problem in isai Ambalam school. We built a pond as a EBD project with the children. Then we realized that water is very precious. From that day we are aware of water. Then one day children noticed that the tank was over flowing. They came and asked how to turn off the motor automatically. I told them that I don’t know how to do that. Then they asked me that I studied Electronics  and  became an engineer couldn’t solve this problem. Then finally I wanted it to be automated. Through this process I learnt about relay. I was afraid to work with 230 volts and it was the first time for me to work with direct 230 volt.

Soldering and Tinkering

Children of Isaimbalam were very much interested in Soldering and making simple circuits. We got many Vega kits were the circuits are already printed in a PCB. Children study the datasheet of a particular circuit and solder. Children from 6th and 7th soldered few kits. They were very happy when some of them worked.

Since they are young and new they made mistakes by flipping few components here and then but they tinkered with my help.

Circuits like Disco light, Light sensor and water level indicator worked.

Bala was so happy when we were testing the water level indicator and the light one by one lighted up. Auyush also connected a buzzer to indicate low light.
