Fixing STEMLAND name board, and understanding SSD

Some of the 7th std children took fixing the STEMLAND name board as a project, they started off by learning how a SSD (Seven Segment Display) works. Then they assembled the units in a bread board, but there was a bug they couldn’t power up with a 9V battery or else the SSD would burn out. To tackle this they added resistors to control the current. The other bug was some of the SSD were common anode and other common Cathode:SSDOnce the type was figured out the SSD were powered up and tested.

IMG_20170301_104402 IMG_20170301_110853

 

 

 

 

 

 

 

  • We had the inauguration of STEM Land at Isai-Ambalam School on the 1st of March at 10:30 a.m.
  • We had friends and our community members and the 9th Graders from Udavi School who came to visit and participate at the inauguration.
  • Then, we all delivered speech on what we want to see and our experience with STEM Land.

After the children demonstrated and interacted with the visitors by

  • Playing strategic games and puzzles.
  • Explaining and demonstrating Montessori materials by the young children.
  • Explaining and demonstrating their electronic and science projects.

List of projects / area which the children had demonstrated for the inauguration.

  • Ayush -(Aravind Gupta Toys) was able to explain and demonstrate that “Moving magnet produces electricity” and “Cast Puzzle”.IMG_20170301_104635
  • Ganapathy,Vasanth Kumar and Sabari were able to build a “Buzzer Game” by themselves and played it with the visitors.

  • Suresh was able to show conducting and non-conducting materials using an electronic project and he was able to build a “Bubble Blower” by himslef.
  • Gowtham and Yuvasri were able to build a circuit which lights up an LED using a switch in the breadboard.
  • Keerthana,Swetha,Kishore and Bala played Dobble,Pylos,Abalone and Othello with the visitors and 9th.
  • The 4th Grade children did a “Welcome board decorated with LEDs”.
  • Prabha was able to demonstrate his project – he had built a “Robot” and was able to communicate with it using blue-tooth from a mobile phone and rotate its motors.IMG_20170301_115510
  • The 7th Grade demonstrated – Equations using Deines block(Montessori material).
  • The 9th Graders from Udavi School also demonstrated and explained how to play Kabaleo , Othello and Rubiks Cube.

My Speech:

  • Its a new experience for us to work with the young children(i.e 4th – 7th Grade).
  • We use Montessori materials to learn math and we also do hands on work(Aravind Gupta Science Toys) to learn some of the  concepts in science class.
  • The children have the courage to create their own science and electronics projects .
  • They are also creative and interested in doing hands on work.
  • The children here are responsible for their learning and as well as for the materials in STEM Land.

Soldering with the 6th Students

The 6th std students wanted to learn soldering, they came up with simple circuits of connecting LED’s to PCB boards and Powering up using batteries. One of them had also seen a buzzer (made in STEMLAND) that produces sound when the circuit was completed and wanted to implement it in the new building of Udavi School.

The students mounted the components and applied flux and then soldered them to the PCB.

Savarayalu 8th Grade Class 20170220

The class started with sharing of what they had learned and the homework from the previous class :

  • Are able to use to ask questions and get answer in the sprite.
  • Are able to move an object using arrow keys and create a maze game.

Setup:

  • The class started by introducing pen operator and the functions in it.

Task given in class:

  • The task was to use the pen function and draw line by the object in the maze game to find out whether the object is moving smoothly or hardly.
  • Then the children worked in pairs with each other and also with their teacher on the pen function and were able to draw line when the object moved.

At the end of the class we shared what was the new things they had learned and how they felt:

  • They said they were happy, joy and proud when they learn new things.
  • Pen functions.
  • Location of X and Y.

Homework:

  • The children were given homework to draw a circle, square and triangle using pen function.

Naveen: I would like to be more rigorous in being prepared for the class and to check their homework.

Savarayalu 8th Grade Class 20170223:

Savarayalu 8th Grade Class  20170223:

The class started with what they had learn t new form the previous class:

  1. Change pen size

  1. Set sprite center
  2. Go to origin in the start of every program and use clear

Task given in class:

  1. Create score and increase it for every right answer
  2. Decrease score for every wrong answer or reset to 0

Activate SqLite Database in Visual Studio 2015

If SqLite does not show up on the server explorer even after installing System.Data.Sqlite package in Visual Studio 2015,

You’ve just got a couple steps backwards.

The issue is that the System.Data.Sqlite package includes VC++ Update 2, but you’ve already got the newer Update 3 installed. Rather than recognize there’s already a newer version installed, all the setup program sees is that installing U2 failed and bails out. So, we need to let it do its thing and install the U2 package to get past that point:

  1. Uninstall “Microsoft Visual C++ 2015 Redistributable (x86) – 14.0.24212”

  2. Install the Sqlite package

  3. THEN re-install Update 3

 Savarayalu 8th Grade Class  – 03/03/2017


The class started with sharing what they learned in the last class:

  1. Function
  2. Variables
  3. how to draw a circle.
  4. Perimeter

Homework from last class:

  1. They completed how to draw a circle and check how many circles can be drawn around a circle with the same diameter touching each other.
  2. I introduce how to draw the above concept in a          different way.
  3. Children were able to draw the circle that i introduced to them.
  4. Then I told them to see the program that our Udavi children made.
  5. Students were interested to do the pie chart program.
At the end of the class they shared what new things they learned:

  1. Pie chart
  2. How to find square root.
  3. In Algebra they learnt LCM from the program.
  4. How to do percentage.

Rigorous: I would like to be rigorous in explaining the program.

Home work:

To look Udavi children program.

Savarayalu 8th Grade Class – 20/02/17

We started by sharing what they learned new from last class. We asked about what did in the last class and also asked about the homework. All student answered that they were able to do the dialogue well. Then we started the class by introducing the pen down and pen up commands today. we showed the program of the ball game and asked them to use pen down command and to follow the path that they created. The children wrote down the commands in their notebook. Then the children sat in pairs and started to code. Some were confused with the motion x-axis and y-axis commands and then I asked some question and made them to find the correct answer. Most of them did well and they understood what the code was doing. They also saved their work in a separate directory under the shared folder. The children coded for almost an hour. We concluded by sharing what they learned today and how they felt. Some children said that they had learned about pen shade, pen down, set pen color, pen size. We gave them a homework to draw a square, triangle and a circle and also gave some hints how to make.I would like to be more rigorous in checking their homework. Sorry I didn’t check the homework.

Controlling a single LED using two switches

During the electronic class that is held on every Wednesday afternoon at STEMLAND, Muthu had built a circuit and figured out how to control a LED using two switch model.

His working prototype is as follows:
