A new Intern (Shivaram) has joined the team, he will be working on Responsive web page development (HTML and CSS), school software and learning to program the mindstorm.

Initially he built a small bot with wheels and learned powering and controlling the motors through the user interface. The batteries were discharging way too quick than expected and caused a halt in the learning.  Then I checked the back of the battery case there were 6 AA batteries connected in series resulting to 9V. I decided to use a power supply and showed him how to connect 🙂 . Now he was all set with uninterrupted power supply. By the end of the third day he had programmed a line follower.

Friday session with STEMLand scaling group – dienes blocks


On 2019/10/03 we had the second meet with the Scaling group. More information on the first meet can be found at : Link

This time Abilash started by sharing what he did in Auroville schools : A simple way to explain how a DC  motor works.

Next as a team we did simple calculations of how addition and subtraction work with carry (Exchanging a rod for 10 units and vice versa or a plate for 10 rods) using the dienes blocks, and later moved to multiplication (Area story) and division with some common misconceptions children have.


To find the length of the arc

This scratch program shows how to calculate the length of arc given a valid angle (20 to 360) and radius (50 to 200). The value  of angle and radius should be given. It requires two input from the user. If the user doesn’t give a valid input it sets a random value for angle and radius.

Inspiration “Secret of concentration”

~ Sundar, Murali, Naveen

Transferred to the next group this week 🙂 , and worked on the secret of Concentration.

The following passages were translated to Tamil and read with the children in both English and Tamil.

From the teachings of Swami Vivekananda :


To me the very essence of education is concentration of mind,not the collecting of facts.If i had to do my education over again,and had any voice in the matter,i would not study facts at all.I would develop the power of concentration and detachment,and then with a perfect instrument i could collect facts at will.

How has all the knowledge in the world been gained but by the concentration of the powers of the mind?The world is ready to give up its secrets if we only know how to knock,how to give it the necessary blow.The strength and force of the blow come through concentration.There is no limit to the power of the human mind.The more concentrated it is,the more power is brought to bear on one point;that is the secret.

Do you see,simply by the observance of strict brahmacharya(continence)all learning can be mastered in a very short time-one has an unfailing memory of what one hears or knows but once.It is owing to this want of continence that everything is on the brink of of ruin in our country.

Herein is the difference between man and the animals-man has the greater power of concentration.The difference in their power of concentration also constitutes the difference between man and man.Compare the lowest with the highest man.The difference is in the degree of concentration.This is the only difference

Take one idea,Make that one idea your life;Think of it,dream of ir,live on that idea.Let the brain,muscles,nerves,every part of your body,be full of that idea,and just leave every other idea alone.This is the way to success,and this is the way spiritual giants are produced.Others are talking machines.

How are we to know that the mind has become concentrated?Because the idea of time will vanish.The more time pass unnoticed the more concentrated we are.In common life we see that when we are interested in a book we do not note the time at all; and when we leave the book,we are often surprised to find how many hours have passed.

During the whole week(201906 22-29) and the sleep over the children worked on creating their own drawings and depicted the following story.

Programming4matheducator Day 8

Day 8:

The day started with reflections from the previous day and then Integrity lens was introduced, Poovizhi handled the session.

Then the teachers presented their projects.

The closing for the workshop began with creating my new narrative with drawing our hands and coloring in values which we stood for. Then it was passed on to all the participants and they each wrote what they saw in us. Once everyone got their sheet back it was amazing to read all the values.

Then we broke for lunch and the session came to a closure, but the participants had requested to conduct a session on Arduino with snap.

Then the Arduino was introduced (Digital and analog pins) the task was to make an LED blink for one second. Then to blink 3 LEDs consecutively. Once that was too achieved fading the LED was done. The participants had a sense of accomplishment with wires and bread boards and LEDs. Then Ram stood up and gave a spiel of thanks for the organization team and invited us to Sitiling.
