Kishor: I learned how to measure the width of tree using thread. We measured the length of the thread using a scale of 15cm. There was team work and we were able to complete the work in time. We measured using creepers as we didn’t have any material in the beginning.
Praveen: I learned to measure width of 5 trees and compared which tree is big, small etc.. We measured the perimeter of the first building.
Guru: I learned to measure length and breadth of the kitchen using thread.
Monika: I learned to measure the width of the tree.
Sharani: I learned how to measure the length and breadth of Anitha’s house and learned to measure the width of the tree in cms
Ajay: I learned to measure the length and breadth of the prayer hall.
Pratap: I learned that our school has trees that have a circumference more than 350cm. The Gaya trees are big and there is a rain tree (Sirish / thoonga munji maram). I noticed that children don’t need to be given certain fixed instruments for measurement. They were able to find innovative ways to measure.
The first time we measured, it took everyone a long time to measure the circumference of a single tree. The next day, we gave the children a challenge to find five big trees. I noticed that they marked the first circumference measurement on the floor with chalk and thereafter, the rest of the measurements were marked in such a manner as to get a relative idea of the circumferences of different trees. The children were quick to note which tree was bigger. It was a satisfying learning and teaching experience for me.
The 5th graders started to build a hot air balloon in Isai Ambalam school. We started gathering information how to make a hot air balloon. Then we watched some videos to make the hot air balloon. We found the reason why the hot air balloon fly towards the sky. The we used tissue papers to make a hot air balloon. The things that are need to make a hot air balloon are glue, tissue paper and binding wire and scissors. we learnt that the hot air moves towards the cold air in the sky and this is the reason why the hot air balloon move towards the sky. I felt the student were excited while doing it . While doing this activity I found the children were responsible for the materials and team work and helping each other and sharing the materials and everyone got equal opportunities for doing the activities.
We had a created a system in STEM land(Udavi school). We started to put up logical puzzles which can be solved logically and as well mathematically. At first we did not have a board to pin the puzzle papers. So, we used to stick it on the wall. Then, we bought a pin board. It was before lunch when I planned to put up the board. Rathinavelu(from 9th grade) and Dievakaran (from 7th grade) can up to me and said that they want to put up the board. I left the work to them. They measured where the holes needed to be put and marked it. Then, they drilled holes on the mark. They took turns in hitting the wood piece and screws inside the holes that were drilled. After all the hard work they fixed the board on the wall.

To mention, they did all this in their lunch break. That day, they went to lunch late.
This showed me that children here want to take responsibility for this place.
They learned how to drill and how to share work their equally.
Shalini, student from 7th grade learned about circle in her textbook. She was learning the topics on chord, diameter, circumference and ratio between circumference and diameter.
She used Geo Board(Montessori material) to learn these topics
The Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around pegs to form line segments and polygons and find perimeter, area and more.
Shalini learning about circle using the Geo Board
Outcomes / What she knows now and is able to do
Chord is a line segment drawn at any two points in a circle.
Diameter is a chord that passes through the center of the circle.
Circumference is the perimeter of the circle.
She is able to find the ratio(which is 3.14(pi)) if she either knows the circumference of the circle or the diameter.
She is now able to use the geo board and demonstrate the above topics to her friends.
The following video demonstrates the nuclear fission reaction that was made during the advanced scratch course offered at STEMLAND. I had partnered up along with a 8th grader from Udavi school to create it.
The 5th and 6th grade children at Isai Ambalam were preparing for the presentation on the last day for their parents. We decided that they can perform2 presentations(Water EBD and Skeleton) and a demo on Measurements. The 12 children were equally split into groups of 4 and each groupchose which topic they wanted to present to the audience. I worked with Water EBD group and Naveen worked with the Skeleton group to prepare for the presentation. The water EBD group spoke very confidently in Tamil when they were presenting it to me in Tamil. But they found difficult to replicate the same in English.
The start of the Saturday classes in Isaiambalam School has enabled a lot of different exposures with various people to the children. Some of the elder students wanted to model Sanjeev’s house with plywood. Then the list was made to buy the materials required and the students came up with the following:
Saw x 2
Hammer x 2
Sand paper x 1m
Chisel x 1
But then we decided to use the old chisel that i had already in my arsenal, Sharpening so it was.
Once the chisel was ready
We started to carve in the windows with the correct dimensions, we took a ratio of 1:10 and descaled the House for the wood model.
Then came the task to build a real door, the children kept on a halt the house model and started to inspect room that required the door and it continued to the next class;
The old mushroom shaped room with no door:
We decided to build a door with some unused wood that was ageing without a purpose. This gave the children a view into measurement. They started out by measuring the dimensions of the door and marked the appropriate onto the wood. Then came the challenge of what joint to select, and we selected an open mortise with a pinned corner.
So began the sawing, hammering, and chiseling works 🙂
We wanted to make the joints perfect and decided to carve the wood to have a
In Isai Ambalam school on Saturdays many activities are done with the students. Last Saturday we did carpentry, gardening. Some learnt electronics and some played strategy games in Isai Ambalam Stemland. We also use math for measuring the wood. We also taught how to cut the wood with a saw.
