Sky Map


I learned about constellation and sky map:


Constellation means group of stars or collection of stars. Yesterday I learned about different type of constellations. Totally 88 constellations are there but in our country they found and named only for 12. Through my experience it was very interesting and I am able to connect the star according to the constellation palan. And I learned about Arunthathi star, usually in our Indian culture  marriage they used to see Arunthathi star after that only they will get marry. After few minutes he introduced sky map. Because we could’t see stars properly.

Sky Map:

Sky map is an application which is used to see stars in the sky. I have experienced with the sky map. I am able see  constellation through the sky map. It was showing all the stars.It was fun and interesting. Here I have attached some snapshot about sky map.








These pictures will show about some of the stars and constellations. Use this application and this will help our children to know about sky and stars etc..

Vipassana Experience


Vipassana Technique was so good for me. It is good to practice for me everyday in life. When I went for Vipaasana I found the first three days difficult after that I realized and understood the universal truth of Dhamma. I learned to live in present moment. This made me to feel better and brighter. I noticed my monkey mind is always jumping thinking about my past and future, but not knowing how to live in present. I am practicing Vipassana everyday it helps me be concentrated, present and peaceful.

They have some ground rules, that is we should not talk to anyone, touch anyone, etc and maintain this noble silence for 9 days. These ground rules support the following the three principal ideas in Vipassana technique – Sila, Samadhi and Panya. Poovizhi has already described these and the theory in her blog and you can read this if you want to learn more.

I enjoyed the real peace and harmony. I understood through my own experience the meaning of Dhamma, it means universal flow of nature and of impermanence. Whatever sensation I feel in my body I was able to accept it and not react to it with either craving or aversion. That helped me train the habit pattern of my unconscious mind and come out of my misery. First day to 10th day I followed the rules and regulation and it helped immensely. In the final day I shared my peace and harmony to others with Metta. Whoever is reading my blog please give a trial for 10 days Vipassana course that makes you feel better and brighter and I am sure you will also come out of all your miseries.

Steps for perfection


Everyone wants to be a perfection on their work. We worked through material provided by Aparajita Foundation (that we plan to use with children) and arrived at the following steps that I found useful:

  1. Clarity of what we are doing.
  2. Collect resource materials, organize and execute.
  3. Keen observation and attention to details.
  4. Be conscious.
  5. Time frame.
  6. Check for completion and correction whatever and whenever necessary.
  7. Clean up.
  8. Trust my work but correct if necessary.

One of the volunteers Sahana put the workshop together with the other teachers at Isai Ambalam School.

Introduction to Analog Layout


There are many things mater in analog passes for success (I.e noise,bandwidth,amplitude and frequency). I learnt few difference between analog layout and digital layout. Compare to digital layout it occupies less space and looks neat. We started doing step by step orthogonality, fourier series, exponential & expansion as sequence, laplace transform. First we did theoretical part that is Rc (Resistor and Capacitor) circuit with the input of sine wave and unit step function. By using exponential and laplace transform we found the output of unit step and sine wave in RC circuit. Now I have started calculating sheet resistance of each component (poly,metal,contact,etc..) that we will use it in magic tool.

Linear Equation with story


We have started with the story of linear equation. Linear equation is nothing but a straight line and choice. For an example we have taken x+y=10. The story of the linear equation is, I and my brother likes chocolates if I get more chocolate obviously he is going to get less chocolate that is the story of the linear equation. After that we have entered into the problem. We started drawing the line for that equation.First I have drawn wrongly for that equation x+y=10. What I have Thought is when the x increases y also get increase equally so the point is (10,10) that is why I have drawn like that.  After that I have understood the function of linear equation. In that linear equation it will get increases by 10 on both the axis.

When I learned how to draw a linear equation. I have made my own question that is x+y=20. Then I have checked my equation using geogebra.

Sinthanai Sangamam with around 600 teachers(Azim Premji Foundation)


Sinthanai Sangamam is happened on 21/02/2018. It is a new kind of experience with around 600 teachers from different places. I have presented a paper about STEM land. The great thing is I got an opportunity to share about, my journey with the children in STEM land.The wonderful thing is that I am in STEM land. Why I came to STEM land is, I want to learn more about electronics that is why I came to STEM. I have learned about electronics what I have learnt that came as a few product that is inverter, display my name using 7-segment display, mobile charger, solar powered charger etc..Then I learned some of the programming from students that is scratch and geo gebra these program will be used in mathematics. These things I have explained in very shortly. In Sinthanai Sangamam everyone shared their experience with the children. How they interact with the children, what method they are following in their school, what kind of projects their students done and how we can connect to science and maths in our real life. The one main thing what I learnt is there should not a gap between children and teacher.

VLSI Layout

In VLSI layout course I learned to design a gates using NAND. Then I have checked the NAND gate truth table with the help of bread board, battery and multimeter. I learned to use magic tool, how to extract and how to simulate the layout.

I learned the cross section of CMOS and what colour coding we have to use for the each components.

Geogebra, EBD & Goanimate

– Saranya

I learned to use Geogebra and have used it to solve a linear equation. This worked for me and it was new to me. It is increasing my interest in mathematics.Now I am eager to solve many equations. Whatever we enter an equation the tool puts the waveform for it. For example, I have taken 3x+2y=0 is a linear equation. From that diagram we can easily identify that is linear equation. This was surprising for me.

I worked on EDB (Education by Design) with students at Isai Ambalam school.The pond which they have built before was cracked by roots of old trees .So because of that students want to reinforce the pond.Now they are in process of adding iron rod and concrete item so that the pond won’t get break again.It was wonderful experience with them.Is very good to see like that students they were full of energy.

I also made a small animated video with it was great idea. It gave an idea of how I can convey something that feels more interactive. It was fun and awesome because whatever we want convey to the students we can convey by making an animation video. It was my first experience with goanimate.I made a video about multiplication story.
Saranya Multiplication Story by SanjeevRanganathan on GoAnimate

Here are some snapshots in case you cannot see the flash content above.

(I.e) there are 3 children, if I gave 4 bananas to each of them how many bananas did I give in all? The answer also I have shown.The answer is 12(add there number of bananas each have and we will get the answer easily).

Different kind of experience with children


RYSI (Raman Young Science Innovator) When we got the circular about Raman award. Students were so excited to do many things in different ways.I have supported few of them.It was different experienced with each children. One of the student is from 9th grade, he wants to measure the frequency.We have connected one micro phone with an Oscilloscope.With the help of an Oscilloscope we measured our heart beat frequency.

I learned about Density(formula). In water, if we place a stone in water, it will sink because the density of the stone is greater than 1. If the density of an object is in less than 1 it will float in the water. Sharani from 5th grade she did density project for Raman award. I just supported her. That was nice experienced with her.

In scratch, I learned to give input from the keyboard using sensing(tool). I have drawn a circle using scratch. Inside the program no need to give radius value I have given radius value from the keyboard.That was new for me.

My first experience with scratch


This is an amazing idea .When I heard the word scratch, I did not know what it is? .After that students taught me how to use it? What kind of thing we can learn by using scratch.It is like an Object Oriented Programming.Here we have to give only command like move,turn like this. We have to understand the logic. whatever the command is given by us It will draw accordingly. We can draw different shapes by using scratch.It is increasing my interest level towards mathematics. The below picture shows the circle by using scratch.

This is makes me to understand the logic in easy way.Yesterday evening I saw the two wheeler truck so I would like to draw the truck by using scratch.Then I tried to draw a two wheeler truck.The below picture can shows my interest  towards scratch.


Learned @ STEM Land



Everyday I am learning new things. This week I have learned to display my name using a 7-segment display and then I made it blink my name using an Oscillator and Arduino programming. The components used were a 7-segment display, resistor(1kilo ohm), battery(9v) and wires. Using these components I have made my name. The picture below shows shows my name using 7-segment display.

For oscillator we need two transistors, four resistors (1kilo ohm,18kilo ohm(depends upon the frequency)), capacitor (1uf or 2.2uf or 10uf). In arduino the 13th pin is for LED and the 22nd pin is for ground. Using this components I have made my name to blink. Here is a video for blinking my name using an Oscillator.


I attended a Stewardship for New Emergence workshop.. In that workshop I was able to find who I am. From that workshop I have learned the difference between who am I and my name. When I told that I am Saranya, Ahmed stopped me and said that his name is Ahmed and he is greater than his name. I stand for love and happiness for myself and others I discovered this from the workshop.


On Jan 24th and 25th we went to Indira Gandhi higher secondary school for the Learning festival. This is the first time a Learning festival has happened in Puducherry. In this learning festival I have learned  how to lead a session for students. This was the first time I have taught electronics to the students. It was nice experience with students and teachers. After the session we went to the other sessions and what they are teaching. I went to a class where I  learned how to make a soap and how to use some things in a several ways(for an example, rope  can be used for skipping(play), suicide, to dry a cloths, to lift something heavy weighted (taking water from the well) etc….). I have met different kind of students. Many students were interested to do electronics. In that festival I motivated them a lot. When they made a mistake I did not help them. I asked them to recheck their connection and after that they checked their connection. They informed me where they made  made a mistake. From that I understood that I should  let them struggle then only they will learn by their own. Finally the Education Minister of Puducherry Mr.V.Narayanaswamy came and visited our session. He saw what the students did with Electronics. Many students did their name and some of the students did their school name. It was good experience.
