Sir C.V. Raman Young Science Innovator Award

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). 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 made her project using GeoGebra. 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)

She did a project on reflection using GeoGebra. 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 ultrasonic sensor to detect the object. When any object is placed in front of the ultra sonic sensor it makes sound. 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.

5.Punidhavel (Class IX)

Punidhavel made a piano using resistors, basar and battery. He made the sa re ga ma tune in his project.

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. 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. He tested it with five watts bulb.

9.Arvindh (Class VII)

He made his project on slow combution explaining the ignition temperature.

10.Pranav (Class VII)

Pranav made a steam engine

11.Vishal (Class VII)

Vishal made a project on combution. A stove using a big tin with holes and one small tin with holes. The smaller tin was placed inside the bigger tin.

Students made their project with their full involvement and felt happy after submitting their innovation project.

Second workshop on Stewardship for new Emergence with the children

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.

My first Blog about what I learnt in STEM Land

This is my first blog and I am going to share what I learnt in STEMLand. I learnt the basic connections in a breadboard and about seven segment display. There are two types of seven segment displays, they are Common Anode(CA) and Common Cathode(CC). I figured out the differences I was able to display my name with the use of wires, resistors, battery and breadboard. It was a new experience for me and I learnt a lot..

After displaying the name, I learnt how to turn on off a LED bulb by building an oscillator. Then  connected both the circuits and made my name blink. I was able to find the voltage across a resistor by using a multimeter.


In the Learning Festival held at Indira Gandhi Government Higher Secondary School in Pondicherry, I learnt more about the SSD’s. We We held a session for the students and the goal was to write their names on the SSD’s. It was a good and happy experience working with students. I visited other sessions where different people from various background had come They made handmade soap, art using coconut shell, naturally made tooth powder, clay works and many more.

I learnt how to interact with students in many different ways, for solving problems in maths, I also got the opportunity to interact with Swati: she introduced us the chocolate plate method for solving questions in division which was new and interesting to solve.
