2017-2018 batch children’s reflection on STEM land

2017 – 2018 batch children from Udavi had a get together. We’ve planned to meet them and have a conversation on how STEM land was useful for them and what they feel about STEM land. Children were in their summer holidays and organised a get together themselves. We all felt happy to see them back. We met them in our lab. Children were also happy to their friends again. We started the conversation by asking them “What do you remember or miss about STEM land and how is it used?” Children shared what they did in STEM land, they shared about their projects and what they learned. Most of them said they learned Scratch, Rubiks cube, Goanimate, solve puzzles and Alice . Some of them said they miss STEM land.

It was interesting to hear children sharing about their projects which they did long time back they really own the work they do. Few children said that they have chosen computer science, computer application and the others who have chosen courses like humanity and language have also chosen computer science as an elective paper. We asked them what prompted them  to take computer science. One of the child said she chose computer science since she miss STEM land. She is studying humanity and she is the first in her class. After the conversation children wrote their answers for few more questions and wrote their memories in STEM land.

Session On New School Software and 7th Grade scratch Course


In STEMland we give freedom to children to choose their plan on their own.  Using the software children choose their plan for a week and they will work according to their plan. We build a software for children to track their progress. The software which we built was having small issues on uploading data also we did it manually, so we wanted to do it automatically.  We got suggestion from our team and children. It took 4 months to complete the new school software.

We had a session with 9th Grade on New school software. Children said it was more comfortable than the old software.

7th Grade children are new to STEM land, so we wanted them to start from Scratch. We explained what is STEM land and ground rules of STEMland. Sundar and Logeshwari started the Scratch course and I supported them to organize the laptops in STEMland. There were five groups. In each group they gave one task. 6 Children from 7th Grade choose to come at during their activity period also. During the activity period they were doing their scratch project eagerly and I supported them to complete their task.

Turning ON/OFF light bulb using Arduino and Relay

~ Abilash, Pratap.

Abilash and Saranya made a relay circuit during the Electronic session with Vimal, so the goal was to turn ON and OFF the AC bulb with the delay of 1 second which was connected to the Arduino and Relay. The Arduino was connected to the laptop and bulb to the 230v Alternating Current through the relay.  Pratap captured the video as a sudden surprise and made the learning rigorous.


Summer Scratch Course

~ Murali, Sundar, Arun

During the school summer holidays,a scratch course was handled by the STEM Land and Auro Aura Team for the Isaiambalam and Udavi students.It was a 5 day course from May 27 to 31 in the morning from 9.30 am to 12.30 pm.Around 18 children participated in the first day whereas from second day another 5 children from auroville attended the course.

Day 1

The course begin with a Stewardship tool, the students were asked about their ‘Stand’ and ‘Fear’. They were all asked to think of a person they admire (It could be any fictional superheroes, but not a person they know related to friends and family) the most and the qualities they have. Not what they did in life. Children shared in groups. Once they sourced their Universal values they stood for, children were asked to think of the social fear they have and how to transcend them. Though they were confused at the beginning, they started understanding the tool and shared on the stage.

We used a performance tracking software that we follow in our school in which children will make plan of what they are going to do in that particular day and at the end of the day, they will be assessing their plan by giving score out of 10. Also they will be making a daily reflection of what they learnt about themself, what will they be doing diiferently of what they learnt.In Scratch they were asked to make a simple game where they used the ‘Sensing’ and ‘=’ operator. Later they created the score variable and made it to increase for every right answer and decrease the score for every wrong answer or reset to 0.Then they used the repeat until function to repeat the same question until the user gives the right answer. They also used the operator block to make simple arithmetic calculation like Addition, Subtraction, Multiplication, and Division.

At the end of the day students were introduced with ‘Makey Makey’. They used it as a mouse by scrolling and played sounds with it.

Day 2

Day 2 begin with the ‘Deep Listening’ Tool. After the Stewardship tool they were asked to display their projects and explained it. Their task for the day was to make different shapes (circle, concentric circle, square, triangle and shapes upto ten sides, and mandala) using pen function.

Finch Robot was introduced to the students. It was connected to a Laptop and was made to run with the help of Brainbird using scratch2.

Day 3

The Day begin with ‘4 profiles’ tool and were given example to understand their profiles.

After displaying their projects, they were asked to make a maze game where they should create their own maze and cotrol the sprite.

They were shown how the interactive camera works with the help of an example code which was already made by the students.

Day 4:

The fourth day started with the Listening and speaking from Three domains(stewardship tool). After that project presentation of the prrevious day projects happened.Then children did their daily plan and then were asked to create score using variables for their maze game which they did in the previous day.They also created randomly moving objects and added sounds.At the end of everyday we used to show some realtime working modules that can interact with scratch.On fourth day it was Mindstorms EV3 which was built by some of the alumni of udavi school.

They built a robotic vehicle and demonstrated how it moves and rotates its arms.children were very excited and few also tried playing with the robot.At the end of the day assessment and daily reflection were done.

Day 5:

The tool for the 5th day was Judgement and Discernment.As usual project presentation happened after the stewardship session.

The task for that day was drawing shapes and calculations (addition, subraction,multiplication,division) of two numbers using function blocks.

The final day wrapped up with children making their final 5 day course assessment and feedback which was followed by a circle meeting where everyone shared their thoughts about the course.

Installing R on Ubuntu 64x

edit /etc/apt/sources.list
paste deb https://cloud.r-project.org/bin/linux/ubuntu trusty-cran35/
sudo apt-get update
sudo apt-get install r-base (first uninstall if already older version R base is installed using sudo apt-get remove r-base)
sudo apt-get install r-base-dev
sudo apt-get install r-base-dev
Y or I : install the package maintainer's version

Paper sorting

We had lot of papers that were unused left from stewardship workshop.

We sorted those papers and looked at how they can be reused again. This activity helped us to identify a system that can be put in place to not waste any papers in future.

Designing New STEMland using 3D tool


What did I do well?

I learnt to use 3D tool in a short time period. I was learnt to use Google sketch up and Sweet home 3D also I learnt to use x-fig which is 2D design. I was not aware of the 3D tool and I searched internet and got input from our team. Then I took all the measurements (Height, Width and Depth) for the tables, windows, doors, cupboard etc…. Now I am able to do design. It gave me a confidence to try more using the tool.

What went well?

I was able to complete do design by using 2D as well as 3D. I was able to cover all the table and boards. I was to do the design with measurements.

Where to Improve?

I was unable to finish it on time I took 3 days (8 hours) to complete the design.

Snaps are available here.

Scratch 3 documentation for Ubuntu

Vimal has completed B.E Mechanical Engineering and has experience in various profiles as executive operations, Engineering maintenance, deputy manager- management systems, quality control in a glass container company 12 years. Presently with Redshade Robotics as a mentor cum trainer for embedded systems and robotics using Arduino for 2 years. Already, he offered an Arduino robotics course for STEM land facilitators.

In the Scratch.mit.edu website release the scratch 3 desktop and Mac Os version. They didn’t release the Ubuntu version. Vimal goes through these websites like node.js, electron.js, github.com/llk/ and  scratch_blocks. And he built the scratch 3_desktop Application for Ubuntu.

And also he taught his knowledge to Sandhiya and Praba. How to do the scratch 3 _desktop Application in runtime.

And We use these two websites like node.js and electron.js to develop any application.

This is the documentation: scratch-desktop

Backyard cleanup for garden

Since STEMland is moving very next to our office, We as a team  decided to cleanup the area between the two buildings(AAD office and STEMland) which was full of bushes and thorns. We want to make sure that everyone using this place is safe as this place was full of insects ,termites, scorpions, snakes, etc..,







We cleared all those unwanted plants/grasses and stones. We have planned to build a table at the center which we could use for meetings and the children can also use this open space for studying outside if they wish. We will be covering the whole space with green shade nets and plant some plants to make it look like a beautiful garden.




















Note:-This work is yet to be continued once the summer is over.

STEM land New Building Plan using Card Board


STEM land is moving from Udavi school to near our office. Which is inside the udavi school campus.  Before moving STEM land we (we refers to STEMland coordinator, Sanjeev and children) want to have basic plan. I did the plan using cardboard. It was helped me to get new inputs from Naveen and 10th grade children. I gave the cardboard planning to the children and children organised the materials at cardboard. It was helped to visualise the new STEM land building.
