Pebble Garden

Children from Isai Ambalam school went to visit Pebble garden. There he explained how to do mulching step by step. He explained how to do a bed and its size. First we have to collect dry leaves and branches. Then dip them in the water started to build a bed. Make a thin layer of with the dry leaves and add soil on top of the leaves. Do it for three time then add charcoal at the third layer. Again do the same process 4 time . Add charcoal in the 6  and 9 layer. After that he explained hoe to treat the charcoal. After doing mulching we have to wait for 2 month and then only we can use it for planting. Finally he explained the process of  vermiculture. It was an interesting trip to learn about mulching and about vermiculture.



Fixing the tube light in Isai Ambalam

In Isai Ambalam prayer hall two tube light were not working. One student asked how to fix it. Then all the student wanted to learn how to fix a tube light. So we started how current flows in a closed loop. Using the tester we showed how to check  the plug point. We wrote  the parts that are present  in a tube light connection. We explained the function of each part . Then they drew the circuit connection in their note book. Next we removed the tube light and started checking the circuit connection. We found that the choke in the tube light didn’t work. We replaced a new choke in the same frame and it worked. Then in our school library the tube light didn’t work.

Water Level Indicator

In Isai Ambalm school 4th and 5th grader were building a simple circuit to check the water level in their school tank. Initially we started to do it in a water bottle. We used LED to check the water level. Suddenly student started to ask every time we need to watch the LED continuously. Then we started discussing what to do and how to improve. While discussing one student told we can use a buzzer which will indicate us once the tank is full. Then we started using buzzer. When the circuit was completed children took took responsibility to fix it from the tank to the motor  box. Children were excited and shared their work. Each one gave their suggestions in a group. Finally all agreed to take the wire from one tree to other till they reached the school tank. The wire that we bought had many knots. One group decided to remove knots from the wire. Some students climbed the tree to tie the wire . Then I climbed the tank and fixed the wire in the tank. Then we turned on the motor and waited for the buzzer to give sound. When the tank got filled the buzzer was giving sound. So the water level indicator works. Teachers and students in our school were excited. It was a good experience to work with children. When the teacher asked many question the student answered correctly and explained the concept properly without mistake.

Building a simple motor:

In Isai Ambalam school we showed Arvind gupta video for the  4th and 5th graders. They saw the video and noted down the materials that are needed to build a simple motor. First day they built and it didn’t rotate. They were sad and went back to their class. Second day they watched the video again and they came to know their mistake. They corrected their mistake and the it rotated. Siva and me explained the concept why it is rotating. From my experience when I built it for the first time it didn’t rotate and I didn’t know what was the mistake. Then It rotated. I learnt that I should never give up easily on what I work.








Activity class in Isai Ambalam school

On Wednesday children had a sleepover in the school. On that day there was a power cut . Children didn’t bring their torch from their home. It was very dark and we had only one torch.  They managed with that torch for that day. At that time students wanted to make a torch in the STEM land. Next day they brought water bottle and they wanted to do it. We started doing and through this process they came to know about the function of a resistor , battery and LED. Finally they built it and they will use it whenever they sleepover in the school.

Measurement – 5th graders

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.

Tessellation kit:

In Isai Ambalam school the 5th graders were able to identify the different shapes using the tessellation kit. They learnt the names of shapes like triangle which has 3 sides. They also learnt pentagon, hexagon, heptagon, octagon, nonagon, decagon. By using the shapes they were making different structures like fish, flower and some mandala structure. I learnt some new shapes names like heptagon, decagon and nonagon. It was interesting for me that I learnt something with the children.



Hot Air Balloon:

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.



Sports Day in Isai Ambalam School:

On Friday in Isai Ambalam School we conducted sports-day for the children. The tasks were sack race, lemon in the spoon, slow cycling, running race, three legged race and Tug of war. We started with the first standard class and conducted till 7th standard. The organizers were Anitha and Sasikala. This was the first time that we conducted these game for the student . I enjoyed a lot and it was a good experience to conduct such activities for the children. Other than the participants the children were encouraging the students to win the game. Handling small children with such activities was very difficult. And I learnt that I need to have lots of energy to conduct such activities. It was a great opportunities for me and others to conduct such activities. For the winners we gave laddu and jangiri for the children. The winner got laddu and the runner got jangiri. All the children were excited and energetic.

Isai Ambalam school on Saturdays

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:

  1. Saw                    x 2
  2. Hammer           x 2
  3. Sand paper      x 1m
  4. 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.
