Children Kingdom

~saranya

Friday (27/04/2018 )was the last sleep over at Isai Ambalam school. Few children’s were in the youth center I don’t know, What they were doing in the youth center. They were took by josh one who is volunteering at Isai Ambalam school and udavi school. I heard about like some sports thing is happening. So I preferred  to go youth center because I want to know what’s happening there exactly. I went there it was like wow!!!!!

Children’s were playing big seesaw, bull ride, tree house, one was like roller coaster and  reverse bicycle etc..  I wonder about the children because their everything is  big but the children does’t have the fear. I can see from the children face. They were saying it was fun and very happy because they were experiencing the joy of youth center. I observed it after that I asked myself that do you want to see or do you want to experience it. And I decided to experience it because we should not accept anything by other’s saying. Because their experience is different our experience is different. When I experienced it, I really felt happy and the experience was very different and fun.  This is the one valuable thing I learned about myself. If I could have miss that opportunity I may missed to learn about myself. So from that I understood one thing about me is “I don’t accept what other’s  saying I will experience it .

About STEM (Science Technology Engineering Mathematics) land

STEM land resource centres are located in Udavi School and Isai Ambalam School, two outreach schools of Auroville. Children come to STEM Land for Math, EVS and science classes.They learn Mathematics, Electronics, 3D Printing, Programming, Mindstorms (Robotics) and play strategic games that enhance logical thinking. The elder children take responsibility for their learning and plan their goals. They only ask for support when needed. This self-directed learning is based on Sri Aurobindo’s first principle of education, “Nothing can be taught”. With younger children we work on real life projects that impact their surroundings. We believe a nurturing environment can support a child’s learning and taking responsibility of his or her learning.

epiSTEME-7 conference

We went to Mumbai from Jan 5th-8th and presented a poster at epiSTEME7 conference in HBCSE (Homi Bhabha Centre for Science Education). Many educators and academics from different countries had come and presented their research and review papers at the conference.

The conference was about research on Science, Technology and Mathematics Education. We wrote a paper on “Fostering Responsibility in Learning in Rural Schools”. We were told that we were the busiest booth throughout the 2 hour poster session. Five of us from STEM land – Aura Auro Design attended the conference. While in Mumbai we also presented this work at IIT Mumbai and TISS.

Skype call with children in Italy

Children from Bianco-Pascoli of Fasano in Italy had a special day for the use of digital at their school. 7th and 8th grade children from Udavi school had a skype conference with them. Children shared their projects on scratch, Geogebra, the models they printed from the 3D printer, an inverter, Vaughn cube and Mindstorm robots. Children from Italy enjoyed watching the projects and were excited when they saw the Mindstorm robots. Children from Udavi also enjoyed sharing their work to the other school children.

Learning Festival

Learning Festival was a large event organized by Azim Premji Foundation for over 6000 government school children with many facilitating groups at Indira nagar Higher Secondary School , Pondicherry. It was a four-day workshop and we hosted workshops on two days. We had 45 minutes with around 30 children each on basic electronics. We asked children to write their names using seven-segment displays. Two children from Isai Ambalam school supported us and handled a couple of session along with us. We had three sessions on the first day and six on the second.

We showed them an example circuit that showed a name. We then introduced them to a multimeter and using it asked them to decode which pin lights up which of the segments of the display. Once they figured out the pin connection we introduced the bread board to them and asked them to connect the seven segment displays on the bread board and light up the initial of the names of all the team members or their name.

A student named John who came for the first session couldn’t complete his name and got special permission and came the next day. He was able to light up his name and started to support other children. The teachers who came along with the children also sat with them and learnt to display the letters using the seven segment displays. In the evening the chief education officer came to meet us and saw John’s work. It was an inspiring moment.

Stewardship workshop for 7th and 8th grade children in Udavi

We conducted Stewardship for new emergence workshop with 7th and 8th grade children in Udavi School. Children were able to find what they stand for and learnt to work from possibilities rather than fear.

They went through the tools including stand, fear, four profiles, Deep listening and background conversations, system thinking, creativity. Every week we conduct triads with children which provides them an opportunity to reflect on where they have used these tools in their daily life.

 

10 principals

About 22 principals of various schools from Mind Mingle had come to visit schools in and around Auroville. They were split into groups and one of the groups with 10 principals came to STEM land.

We gave a broader picture of what we do and how children learn in STEM land. Then they went around STEM land and interacted with children. They saw the weekly puzzle, weekly plan. Children showed them how they fill their plan using the software, Hariharan solved Rubiks cube, on the other side Viknesh and Kabilan were demonstrating their Makey Makey project in which they made a mouse using a rubber chappal. They looked at the Montessori materials.

In the next room children were printing a fidget spinner in 3D printer, some of them were working on Alice and Scratch.The principals were happy to see children printing 3D models and sat along with the children to learn how it works. Children showed their projects and gave them some cast puzzles to solve. Some of them played games along with the children. It was interesting to see children sharing their learningwith the principals from various states without any hierarchies. Each principal said they learnt something from the children and said STEM land is a nice learning environment with freedom. One of the principals said that she was touched with what we do and wanted to implement it at her school.

Courses conducted

We conducted a basic VLSI course. Around 16 participants in and around Auroville came to learn.

We focused on Digital layout. We did an inverter and simulated it using LT spice. Built the logic gates using DM74S00N and bread board and tested whether the logics were appropriate. We layed out an inverter using Magic and layed out XOR gate using NAND gates. The next course will be on Analog layout.

Sinthanai Sangamam

Sinthanai Sangamam is an annual symposium on education that happened on 21/02/2018 in Puducherry. Around 600 teachers from different places have participated. We presented our paper about STEM land in Isai Ambalam School and the EBDs we do with children. People shared their experience of interacting with the children, the methods they follow in their school, projects their students have done and how we can connect to science and maths in our real life.

Visitors

This quarter, we had around 82 visitors and 34 children to STEM land.

Government school teachers visit

Around 37 government school teachers and people from Azim Premji Unversity came for training at STEM land. Some of the teachers had heard our presentation at
Sinthanai Sangamam symposium on “STEM land in Isai Ambalam School”. Some of them were inspired from our talk and they came to visit STEM land. People saw what the children had created at Isai Ambalam school and interacted with the children working on their EBDs.

After that they visited STEM land in Udavi school. Children showed them few projects. The teachers also tried to solve cast iron puzzles. We also conducted a Stewardship session for them following lunch.

Project work

Children did projects on math concepts like Pythagoras theorem, finding squares, Probability, Geometrical concepts and theorems in Scratch, Geogebra and Go animate. They also did projects related to science. Even on a Pongal holiday children wanted to come and do something in electronics. They split into teams and built a microscope by hacking a web cam and the other team made an inverter using Arduino.

Children from both the schools from 5thto 9th grade participated in the Raman Young Science Innovator Award and created science projects. They chose their topics which were given under different grades and innovated their projects on it. Children were active and enthusiastic to complete their projects and submit them. The whole atmosphere for that one week was energetic and busy.

Swati in STEM land

Swati Sircar is a teacher trainer at the Azim Premji University in Bangalore and visited STEM land for a couple of days. She had completed MS in Math, M.Stat., B.Stat. (Hons.), and works with many NGOs and government school teachers. She is keen on hands on activities, explorations, open-ended questions as well as computer aided learning. She is also an origami enthusiast and uses her Montessori exposure in her current work. She came to STEM land and took sessions for the teachers and children on mathematics and showed us to use montessori materials like Ganit mala, Pythagoras theorem, place values and counters for addition and subtraction

 

 

Workshop on energy with Transition children

3rd grade children in Transition school are studying about energy and its types. About 19 children came to STEM land to learnt about energy. They learnt about converting electrical energy to light energy. We asked children to light up LEDs and measure how bright they can light up using resistors and batteries. They learnt about +ve and -ve charges and to connect an electrical circuit. Children also enjoyed working with multimeter, 9V battery, resistors and LEDs.

EBD (Education by Design)

EBD(Education by design) is a process in which a real life challenge is given to the children. Once the challenge is given children learn through designing and researching solutions for the challenge. At the end they build a product/model with certain criteria. At Isai Ambalam School we have been looking at education by design including creating an India map and studying and creating models about Geography of India. We also took on real life challenges to reuse kitchen waste water to the garden.India Map EBD (Education by Design)Students from 6th and 7th graders made India map using red soil, clay, bricks, pebbles, sand, alluvial soil, black soil. They created the India map in a 3metre x 3metre area. Each student were given separate parts of the country to draw. By using graph sheets they drew the map of India.

They made the structure of India using clay. But after a couple of days it had cracks. Then students came up with a solution that since the layer of the clay is so thin, it had cracks. We had some remaining soil left after another Education By Design (EBD) projecy where we had constructed a clay kiln, so students used that red soil and created another layer above the clay. By using bricks and red soil students built the mountains. In order to differentiate between desert, mountains and rivers they used different materials. For the rivers they mixed cement with water and built many rivers in the map.

For desert, they used sand. In the eastern parts of the country, they used alluvial soil to demonstrate the rivers taking alluvial soil to the delta before joining the sea. Tasks were properly divided among students and it took about two weeks for them to complete the map. The final output of the map looked good with mountains, rivers and other geographical features. By doing this EBD they learnt the Geography of India.

Auro Sangamam

Auroville celebrated Sangamam where all the workers and their families from the bioregion came together and enjoyed the events. We were allocated a stall for STEM land. Three children from Isai ambalam and 4 children from Udavi came and they set-up the stall. We asked people to display their name or their first letter using the seven segment displays and played games like Abalone, Pylos, Dobble and gave some challenging activities like solving Rubik’s cube and cast iron puzzles. People enjoyed solving puzzles and displaying their names in seven segment displays. We gave a talk about STEM land under unending education in Auroville. After visiting our stall in Sangamam an engineering graduate was interested to learn more about technology and he started to come to STEM land.

Volunteers
Josh had visited STEM land one day and found it interesting. He kept coming back for three months while he was in India. We are happy that his travels have found him back in Auroville and at STEM land.

Josh has taught at Western Washington University and at Seabury Hall, Maui. He has a passion for Maths and in this stint is keen on developing his skills in programming.

Sravan Reddy has studied engineering physics at IIT Delhi. He works at Dimagi, a social development enterprise, as a software engineer. He has been regularly coming to Auroville for inner development and volunteers in STEM land. He visited STEM land and the i-SMART class room and came to know about the courses we conduct for youth in and around Auroville. He is interested in conducting a course on creating good software using Python and designing websites along with Django at STEM land.

Kitchen waste water treatment plant

Kitchen waste water treatment plant is an EBD (Education By Design) and its main objective is to reuse the kitchen waste water for watering the garden. We decided to create the waste water recycling system, in order to reuse kitchen water to water plants.

Through the EBD, children learnt the following
Measurement of Height and Circumference : To measure the height of the tank we used a bamboo stick. Children marked the height of the tank on the bamboo stick. We used a thread to measure the circumference. Children took the thread around the circular shaped ring and marked on the thread. The challenging part was we were not able to find the measuring tape and used the metre scale instead. We found that the height of the tank was 3m and Circumference to be around 3.14m. Through this we found out that the radius was half a meter. Finally we found out that the tank volume was approximately 2355L.

fixed a motor to pump water from the pit. Eventually, the pumped water is used to water the garden. A circuit is connected to the water tank which indicates the rise in the level of the water in the pit.

Concreting the Pond EBD

Children made a pond in their school as an EBD. After 6 month it developed a crack because of the roots from the trees around it. After that we sat with children and had a conversation about the pond. One child asked how about concreting the whole pond.

Then we used 6mm and 8mm iron rods and bent them along the contour of the pond. While bending the rods, children learnt about the the rod size, name of the tools we used, measurement, volume, and ratio.

The bending and cutting of rods were done by the children. We bought 40Kg of 6mm 50Kg of 8mm rods for the pond.

Children made 100 TMT rings to make a beam structure around the pond. After the rod work was done, we bought 1unit of sand, jelly and 10 bags of cement. We hired a mason in the end for mixing the jelly and for smoothing the pond. While doing EBD we used to have question section, during that time we will discuss children’s questions and clarify them. While doing EBD children connected with their theory in their books and understand the concept well.

Vegetable Garden EBD
Children in Isai Ambalam school wanted to make a garden in their school. We had visited Botanical garden and Pebble garden. We saw different ways of making a garden. We wanted to set up a drip irrigation system in the garden using sprinklers. We started planting in the beds we had prepared.

Children from 6th and 7th graders took responsibility to connect sprinklers all over the garden. It was a new experience connecting sprinklers and routing the pipe to our garden. We are starting to see plants coming up in the garden.

Children take turns to water the plants. Now they give all the vegetables that they harvest from the garden to the school kitchen.

Our Team
This quarter Logeshwari, Ranjith and Saranya, all Engineering graduates, joined us as part of an internship program which takes the current team size to 10. They are learning programming and electronics and are supporting children in Isaiambalam to complete the EBDs. They are also working on hands on projects and have attended the VLSI layout course.

Setting up Cadence and Centos

Install Centos:

Did not work:

  1. Installed Centos 32 bit OS.
  2. We realized that Cadence need CentOS 64 bit OS .

To find the OS and CPU do

  • # lscpu
  • It should give something like this:
    • Architecture:          i686 == this indicates the OS
    • CPU op-mode(s):        32-bit, 64-bit == this indicates the OS

Worked:

  1. Installed Centos 64 bit OS KDE version. Download LiveCD version with KDE or other desktop (we did KDE)
  2. Somehow we changed KDE to Gnome version of CentOS.
# yum -y groups install “GNOME Desktop”

Note: If you want  to install a KDE version please use the following command:

# yum -y groups install “KDE Plasma Workspaces”

Below link will help you to install various Desktops:

https://unix.stackexchange.com/questions/181503/how-to-install-desktop-environments-on-centos-7

  1. We installed CentOS 7.4

To check what version of Centos you have use the following command:

cat /etc/centos-release

 

Install Cadence:

Installsacape:

https://www.cadence.com/content/cadence-www/global/en_US/home/support/software-downloads.html

  1. We used Iscape to install all the packages needed for Cadence.
    1. Unzip and untar the file in a directory
    2. tar -zxvf IScape04.23-s012lnx86.t.Z
    3. iscape/bin/iscape.sh

This will open up a GUI:

Iscape is a user interface where we can install packages by giving a control file. This control file will have all the packages and will automatically download , install and configure the packages you want.

This is little tricky. When you load in the control file

  1. Search and give control file

In our case the control file was called

Control_30192_309C233F31F1_3_21_2018.txt

Note:

In installing we got many errors and we were not able to install the complete package.

Install the latest of everything i.e. HotFix if available

  1. The directory of downloads and installs is

/home/stemlandaad/cadence

We missed the name of the user so we created another userWe added something to be able to use the UI to add a user.

# sudo yum -y install system-config-users

 

Configure:

We need to configure the licenses.

http://ece451web.groups.et.byu.net/cadence-help/getstarted.html

After configuring,

To run Cadence:

Start terminal and type

# csh

Constellation

-Ranjith, sanjeev, saranya, and Logeshwari

In this week sleep over, children wants to see a moon in telescope. we setup the telescope, but we did not see the moon in our telescope. Then two persons came from Puducherry science center & Planetarium and they tried on telescope. They found out there is some parallax error in telescope and all of us get disappointed. One person from planetarium show us group of seven stars { ( hindu astrology: saptarishi mandalam ) , ( astronomy: Big dipper ) } and told us name of stars in that constellation and way to find the north pole using pointer star on Big dipper constellation. After that we all went to terrace to see more constellation and he show us Leo Zodiac constellation, and children ask him to show Libra and Cancer zodiac constellation, but we can’t see that. Then children ask him why there is not star. He explained that, there is stars but we can’t see due to light pollution ( bright moon light ). After that he show us presentation which consist of information about constellations, Galaxy, and life cycle and star ( change in color over it life time ).

Sky Map

~saranya

I learned about constellation and sky map:

Constellation:

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..

Shell commands

I learnt about shell commands. A Shell is an environment which is used to run our commands and programs. It is an user interface with the operating system. There are many different types of shell. I learnt some commands in bash and C shell. Bash is one of the original shell which developed for UNIX computers. C shell was developed based on model of C programming syntax. To know which shell you are using type echo $0.
I learnt how to define variables both in bash and C shell. Bash is denoted by $. The syntax to define a variable is $a = 5
To print the value of the variable use the command echo $a. In C shell we need to set the environment variable. So the syntax goes like this. setenv a 10. An environmental variable has the name and the value.
To go to the home directory ~/.cshrc and ~/.bashrc for C shell and Bash respectively.

Stewardship for New Emergence in Tamil Program April 2018 (Appa Amma Program)

– Naveen

Stewardship/Leadership and capacity building workshop in Tamil for full potential in the workplace, home, and community.

Facilitators:

  • Srilatha Juvva is a professor at Tata institute of social sciences.
  • Suriyaprakash C is Professor of Organizational Behavior with Jansons School of Business, Coimbatore.

The goals of the program was that an individual attending the program:

  1.  moves from resignation in workplace towards action producing results toward common goals.
  2.  builds capacity for increased personal confidence and drive for inspired-action.
  3. transforms attitudes of blame, complaints, and gossip towards responsible speaking and actions.
  4. foster a wider mindset of inter-community sustainability and well-being for all.
  5. support workplaces to become environments of learning and unfolding where action becomes integrally directed towards common goals.
  6. cultivate accomplishment.

Arun, Bala and I were part of the organizing team and PC (Practitioner Coaches) who were holding tables and conducting follow up traids. As part of the administration I took up the accountability for preparing the handouts and of breakfast of the team holding the event. 

I was holding a table as a PC (Practioner Caoch). This gave me an opportunity to practice my role as a PC as distinguished from a coach as I gave examples from my life to illustrate the tools and distinctions. In giving these examples I was also able to notice gaps in my actions. It also gave me an opportunity to improve my Tamil writing skills. I was able to write in Tamil for the participants who were not able to write. 

During the CFSR(Conscious Full Spectrum) tool, I shared my project in the stage which helped me to make my project more clearer. I also found a partner there from the audience with whom I could work because she was also doing the same kind of project. My project was one Lets Talk Trash- A team of Auroville youth cleaning and creating awareness in and around Auroville.

I was also given the opportunity to practice feedback for growth (as distinguished from diminishing feedback or advice) to each participant in my group when we did Speaking Powerfully exercise. 

My Insights:

  • I was able to notice my what was missing in my actions and worked toward filling the missing actions.
  • I noticed that I was assertive while handling the table.
  • I made sure that what I did was for the growth and exploration for others.

Other Insights:

  • Most of the participants in my team were able to speak powerfully during the the Speaking Powerfully exercise in my group.
  • I was in integrity in attending the workshop.

I need to practice, practice, practice.

This is the project with which I filled out the CFSR on the stage.

Children building a tree house in their school

– Pratap

The children at Isai Ambalam have been wanting to build a tree house for some time. Josh a volunteer who volunteered at STEM land in the past spent some time at Isai Ambalam and had some experience with building tree houses. He decided to put in an effort and work with the children to get this done.

          

 

With the help of the children and some very nice tools Josh brought with him the children were able to help him use the bamboo on campus for the main sections of the tree house. Josh was very impressed at how comfortable and efficient the children at the school are at using tools. In addition, we needed other materials like Pakku Maram and coconut ropes which we bought from the local shops.

One of the earliest activities that the children got involved with was tying up the coconut ropes into quickly usable bundles. This was Josh way of testing if the children could tie things tightly.

Josh also called the tree house community to help with the core aspects of the tree house so it is robust. The children were also asked to imagine how they would like the tree house to be once the tree was selected close to the play area.

    

Josh came in on a holiday and worked on seasoning some of the bamboo, by burning it and then applying a combination of cashew oil and diesel which keeps termites away. They performed a small pooja at the tree thanking trees for giving us oxygen and supporting life and supporting our Number 54 (the house with a bamboo door) tree house. Josh had also taught the children a song about trees in English and the children sang this song as well.

 

One of the designs was selected in which the ladder went through the floor in one corner and the machaan would be built there. Within the day there was a framework with bamboo supported in one place by a work tree. Tying the rope for the main structure was hard and only the elder children were able to do this initially. Josh then showed the children how to work with the Pakku Maram. They did this over the next couple of days the children measure cut and created a complete platform and a short keep out wall that makes it feel like you are in a boat in the air.

Another major task was making the ladder and the children were involved with this and in making a small structure at a lower height for the younger children to have something to climb on. Of course, it is impossible to keep anyone off the tree house and everyone wants to be on top of it. Initial work on bamboo, cutting to size, Pakku Maram measuring and cutting. Narrow opening to get in and the boat in the air.

Vipassana Experience

~Saranya

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.
