Along with the 6th graders from Udavi school, the children wanted to build something to show to their parents. Initially a few weeks back we had build cubes from chart paper. Then I remembered once Ravi A who had come to Isaiambalam to show his work, had introduced some kirigami and one thing that really got me amazed was an infinity cube he had built. This idea struck me and we along with the children decided to convert their cubes to an infinity cube.
Raman Young Science Innovator Award is a contest for students studying from III to X standards grouped into three. Students from IIIto IV, V to VIII and IX to X. We heard about this contest and started registering for it on 31st January. The registered students got their login credentials through their mail after 31st January. We submitted their projects on the last date on 10th February (extended to 12th February). Eight students submitted their innovation projects from Isai ambalam School. They are Ayush Jena, Suresh and Vasanth Kumar from class VII. Balamurugan, Kaviya, Sabari anandh and Yuvasri from class VI and Sharani from class V.
Ayush Jena (Class VII)
Ayush chose the topic buoyancy. He made an animation using scratch which explains the buoyancy of ships.
Suresh (Class VII)
He made his project on conductors and non-conductors.His main objective of the project is to find if the material is a conductor or non-conductor.He made a circuit and placed in inside a box.If the material is a conductor then the light will glow. If the light doesn’t glow then the material is not a conductor(non-conductor).The materials he used to make this project are wires, bulb, battery, box and iron.
Vasanth Kumar (Class IX)
Vasanth Kumar chose the topic Plant Kingdom. He took banana and he made an animation using scratch.In his animation he explained the benefits of bananas, scientific names and different things about it.
Balamurugan (Class VI)
He chose the topic density. He took a bowl of water and filled water upto 100 ml. Then he put some stones in the bowl until the water level rises to 110 ml. Then he took the stones in the bowl and weighed them with a weighing machine. It was 100 gm, which is equal to the rise in the water level.
Kaviya (Class VI)
Kaviya made her project in convection. She experimented by using coloured ice cubes. She was able to see the colour of the ice cubes get sink in the water. She observed that the speed of the speed of the ice cubes dissolving in water.
Sabari Anandh (Class VI)
Sabari chose the topic Plant Kingdom.He made his project using scratch. He selected neem, squirel, mamgo and described their important characteristics. Then he explained what is the connection between them using scratch.
Yuvasri (Class VI)
Yuvasri chose the topic melting point. She tested the melting point of ice cubes. She understood why the ice cubes melts when heated and what happens when heated.
Sharani (Class V)
Sharani chose the topic density. She took honey, vegetable oil, soup oil, coloured water and syrup. She poured all the liquid one by one glass bottle. Honey settles down because it has density greater than one. Similarly she formed five layers in the bottle.
Raman Young Science Innovator Award is a contest for students studying from III to X standards grouped into three. Students from III to IV, V to VIII and IX to X. We heard about this contest and started registering for it on 31st January. The registered students got their login credentials through their mail after 31st January. We submitted their projects on the last date on 10th February (extended to 12th February). 11 students from Udavi School chose their topics and submitted their Innovation projects. They are Abitha, Amsavalli, Hariharan, Kabilan, Punidhavel, Suriya and Vignesh from IX standard. Baranidharan from VIII and Arvindh, Pranav and Vishal from VII standard. The topics were based on their standards.
Abitha (Class IX)
Abitha chose the topic refraction. She studied about refraction in her academic books, so she thought of making it in practical. She made her project using GeoGebra. GeoGebra is a Dynamic Mathematics Software (DMS) for teaching and learning mathematics. She used two mediums. Both of them are air. The incident ray and the refracted ray has the same angle. The refraction index of the second medium increases then the angle decreases.
2.Amsavalli (class IX)
Amsavalli did a project on reflection. She did her project using GeoGebra.When the incident ray falls on the mirror and the ray gets reflected. This is the reflected ray. She showed the angles of the reflection in an animated form.
3.Hariharan (Class IX)
Hariharan chose the topic frequency. He made his project using Arduino. He used an ultrasonic sensor which will detect the object. He wrote his program in Arduino. When any object is placed in front of the ultra sonic sensor it makes beep sound. When the object is far from the sensor the volume becomes low. Based upon the distance of the object to the sensor, the sound will differ.
4.Kabilan (Class IX)
Kabilan made a microscope using a mobile phone and lens of laser light. He placed the object on the lense and it shows the enlarged image of it in the mobile. He made this microscope, because when he was using a microscope the light hurt him. So he wanted to make a microscope which does’t hurt. He tested the microscope by seeing the microscopic view of leaves and insects.
5.Punidhavel (Class IX)
Punidhavel made a piano using resistors, basar and battery. He made his connections in a breadboard. He used resistors and buzzors to make sound. After completing the project he made the sa re ga ma tune.
6.Suriya (Class IX)
Suriya made a pie chart using GeoGebra about the natural gases in the atmosphere.
7.Vignesh (CLass IX)
Vignesh chose the topic frequency. The materials which Vignesh used are ocilloscope, microphone and 341 tuning fork. He measured the frequency of tuning fork with the help of microphone and oscilloscope. By using this we can also measure the heart beat frequency.
8.Bharanidharan (Class VIII)
He made an inverter using Arduino. The materials he used are Arduino, Breadboard, voltage regulator, resistor(10 k ohm), 9V battery, transformer, wires and laptop. He made a program to blink the Led at 50Hz. Then he dumped the program in the Arduino. He connected it to a CRO and saw the square waveform. Then he connected the remaining circuits on the breadboard. He used the voltage source from which nine volt DC input is fed to the transformer. The output of the transformer is 230 volt AC. After that he connected a 5 Watts bulb to the ouput. Eventually the bulb glowed.
9.Arvindh (Class VII)
He made his project on slow combution explaining the ignition temperature.
10.Pranav (Class VII)
Pranav made a steam engine.He took two wooden pieces and on each edge he made a hole and put a screw. He placed a tin above the wooden pieces and stuck it with glue. He made a hole on top and one side of the tin. He broke the pen into two and inserted each piece in the two holes. Then he kept a motor which was connected to another wooden piece. A Led was also connected to this wooden piece. When fire is lit up, it goes through the tin and it makes the turbine to rotate.
11.Vishal (Class VII)
Vishal made a project on combution. He made a small stove using two tins. First he took the small tin and made holes then the bigger tin and made holes in it. The smaller tin is placed inside the bigger tin. A vessel is placed on the tin. Using small wooden pieces he made fire. He poured water in the vessel, which got heated quickly.
Students made their project with their full involvement and felt happy after submitting their innovation project.
How to make a concrete structure using cement, jelly and sand. Children wanted to make a beam around the pond. To make a beam they wanted to they need a iron rods. We bought the iron rods and the tools to bend the rod into a rectangular structure. First time when I made a TMT Ring it didn’t come in proper way. 5th time I got it correctly. Children were excited and they were watching me seriously. They found the patterns and how to bent the iron rod. One child from 4th standard took effort to draw the actual ring size using a on the surface where I was making the rings. Then Children started to do and they found the pattern how to bend the rings. They told the that they need to bend it 90 degree. All the children used the ring structure that the boy drew which was very useful to bend the ring at the right size.
In Isai Ambalam School I was introducing multiplication as area to the 4th graders. Children were having difficulty to do two digit multiplications. So we started using graph sheet to solve multiplication. We started with single digit and then we build on it. I found that using graph sheet children could only see the area and couldn’t build on it. Then children started to use Denies block. Children who were having difficulty started with the Dines block. Children who felt confident started to use scale and measuring tape to measure the object. In STEM land children started to measure the entire object which were in rectangle and square shape. They kept the Dines block on each object that they wanted to measure. They started with a note book and ended measuring the white board. Children also understood that they need to know the length and width to find the area. Children were able to calculate and checked how many 1cm² (centimetre) cube can fit in that area. I also introduced the unit convention to the children I told cm square. One child wrote cm and drew a square on top of cm. Then I explained him that what he wrote was correct and for writing convention we write it as cm².
On Monday, 29th January we had the second session of the workshop – stewardsip for new emergence. In this workshop we discussed about four profiles namely wisdom, social personality, and professional From the four profiles the one that I could connect the most was my professional profile. I am now working on a digital clock, I haven’t completed it yet but the insight of being a professional reminded me to try and complete the work that I am doing. Initially I had no idea of where to start and what to do. Now I have learnt about the counters and decoders which is used in the digital clock that I am creating. I was also able to recall the Karnaugh Map which I had studied in my college days.
The 6th grade wanted to build name boards for their class. We started by learning how a multi-meter works in order to check for the connections in the bread board and to test the SSD’s
Now the batteries were low and the children started by opening the meters and replacing the batteries.
Once the multi-meter were functional, we started to hack and learn the connections in the bread board by testing for connectivity..Then children were given each and CA(common anode) SSD and asked to bias them to find out the corresponding light settings for each segment. With the available information they gathered they had begun to build the name boards.
A person called Sri.M has been invited to Auroville. He is considered to be a living yogi who has apprenticed with Babaji in the Himalayas. He is a spiritual guide and runs Satsang foundation that runs schools, health care facilities and a Walk of Hope that spans 7500 km over 11 months. Before he came to school teacher made small kolam at the entrance and decoration with flowers. When he came to Aurovill he came to Isai Ambalam School. Many visitors came along with him to the school. He came and sat and spent about 20 minutes interacting with the children. He asked the children to sing a song. Children sang a song about Mother. Then children presented a bamboo torch and a STEM land brochure. Then Sanjeev Ranganathan gave a brief introduction about the school. The visitors started interacting with the children in small groups. Along with him children started to walk for some kilometre and came back to school.
Children in Isai Ambalam made a garden inside their school campus. On Saturdays children come to school and cleaned the place.They formed mother bed and planted some vegetables. This Monday they harvested their garden and brought some broad beens.
They went around the school to every classes showing their beens to their friends and teachers. They were so proud to say that they got it from their garden. They have also brought a tiny potato from their garden. It was their first experience and were so happy to see natures gift for their hard work and their compassion towards nature.
