Makey Makey

9th graders finished their assessment and made a scratch program by setting different sounds to various keys. They played musics by conducting different materials like paper, compass, leaves and some aluminium pieces. They worked as a team and enjoyed a lot. They played drums sound and came up with their own music which made everyone to come and see what they were doing.

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.

Magic garden

First the class started with how many plants 5th graders wanted to plant in the garden. Then we decided to plant one plant for each foot. The problem started there. Children doesn’t know how much a foot is. Then the conversation went on and the children said that a foot is our foot. Exactly the foot is our foot. A foot is approximately the size of an adult foot. Then the children converted the meter dimensions of the garden they earlier measured into foot.

We went to Botanical garden after that to buy plants. Children were excited and we chose some plants and bought them. Then we came and planted them in the garden.

Each child took different responsibility and planted all the plants. Anitha gave few plants she had.Children also wrote the names of some plant they saw in the Botanical garden.

Cubes Rods Plates – 3rd grade

I introduced the Dienes blocks to the 3rd graders to get a sense of ones, tenths and hundreds. Each cube is one, a rod is a ten and plate is a hundred. I asked them the following questions

  1. How many cubes can make a rod?
  2. How many rods can make a plate?
  3. How many plates make a cube?

Then we noticed that the pattern repeats itself : cubes – rods – plates – cubes – rods – plates ….. and that everytime it increases by 10 orders of magnitude.

The children had fun trying to keep the blocks in their hands. Some children were not able to hold it but they all tried.


Children were supporting each other while building a design in Kapla and were very concentrated in building it. They were creative and encouraged each other while building it. They had lot of perseverance and patience while doing it and at the same time they enjoyed a lot and were so proud after completing their design.

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.








Leaves with 3rd graders

The 3rd grade children of Isai Ambalam School collected different leaves from the school campus. They were able to differentiate the shapes, colour and texture of the leaves. We watched a video on why leaves change yellow in colour. They got to know new words like stem, branch, root, chlorophyll etc.. They were able to draw the different parts of the plant in their notebook after watching the video. We also made made an Herbarium model after collecting green leaves and drying them in their notebook/book

Garden – Filling up with sand

Saturday school already started with disappointment when the hot air balloon again failed to raise up. Then we thought of finishing with what we started. The garden which we built has to be filled with soil to plant plants. It was somewhat time consuming and exhausting to get red soil outside school. Then we looked around the school and found interesting solution.

There were burnt ashes left and decomposed compost from the dry leaves of bamboo trees. We decided to mix Ashes, Sand and Dry leaf compost to fill the garden. The activity started and the children mixed them and almost filled the garden.

Software to track students learning plan

Pratap and myself were working on a project to create a software which tracks the students learning plan. We did it in Django. Before students were filling their daily plan and weekly plan in an excel sheet. Typing in it was difficult for them and took much more time to fill it. So we thought this software would be much easier for them. This software contains weekly plan, daily update and weekly update. They can select their standard and name. Once they select their name their picture with things that they liked most in STEM Land will appear. In weekly update they select their goals for the week, in Daily update they select their plan for that day and in weekly update they say how much they were able to complete their goal and what will they do different in next week. Through this software they come to know where they are and how they utilized the time and where to improve. We showed the project to the student and the were really happy to see it and did their plans within few minutes.
