How to find a value of Capacitor

A capacitor is a two terminal passive element which stores energy.

There are two types of capacitor.

1. Ceramic Capacitor:

           Ceramic Capacitor

– These are small,non-polarised in yellow or orangish  in color.

How to identify these capacitor values:

The value is printed in three-digit code. The first two digits are the two most significant digits of the value, and the third digit is the exponent on the 10. The value is expressed in terms of pico-Farads.

For example,

104 becomes “10” followed by “0000”(four zeros) or 100000 pF, which can be written as 100 nF.

2. Electrolytic Capacitor

           Electrolytic Capacitor

– larger cylindrical bodies that look like small soda cans

– higher capacitance than ceramic capacitor

– they are polarized

 

How to identify these capacitor values and its polarization:

The value is followed by the voltage rating(maximum DC voltage the capacitor can withstand without damage).

Polarization:

There are two polarity indicators on an electrolytic cap:

1. The stripe painted on the body usually denotes the negative lead.
2. The positive lead is longer than the negative lead.

For example,

1000uf 25V – Thousand micr farads and 25 volt.

Peer learning in 8th Grade

Anisha,Janani,Sivasakthi,Sindhu and Larasem were working on geometry in finding the angels for triangle with the other angles given directly or indirectly. They had some confusions and started to discuss among themselves by working out in each others notebook. Later, each took turn and used the board to frame their own questions and  asked the others to solve. Then they discussed among themselves in how to solve the question.

What they learned in the discussions are as follows:

  • There are three angles in a triangle.
  • They know that the sum of angle in an triangle is 180 degree.
  • Intersecting angles in a straight line is 180 degree.

Fixing the 3D printer in STEMLand

The 3D printer in Stemland was not printing the model at the centre of the plate. It started to print the models at the corner of the plate. When I looked, I found that the trigger switch that was to locate the x-location was broken. So, I had bought a new trigger switch to replace the broken switch.

Pranavraj from 8th grade was working on the proof of the area of parallelogram is equal to the area of rectangle with same base and height. He wanted to create a 3D printed model for that. I supported him in creating the model using blender. Then as the 3D printer was broken he was not able to print the model. He helped me in replacing the trigger switch. Then we replaced the trigger switch. The new trigger switch is not able to get triggered when it hits the screw for the x location. This needs to be debugged.

Project Presentation by 8th Graders

This week Larasem and Sindhu from 8th Grade in Udavi school presented their project on Geometry to the 8th and 9th graders. It was a simple Scratch program where they showed a triangle and calculated the third angle of  the triangle by giving two angles.

This was their first time to present a project and they did it well and also answered the questions too.

The program had only fixed angles and they were not changing automatically. Then Sanjeev showed to the children on how to create a variable and make the angles to change randomly and also add the tick to the angles using ‘join’.

Practicing Breakdown to Breakthrough

As a team we practiced the Breakdown to Breakthrough exercise. First day we did the session with the Tamrai Team. We did the exercise together and shared our insights in a pair and as a group. On the second day, we continued it for the breakdowns which we had for our team.
We had fun as well as we came up with action items and new ideas for the breakdowns we had in our team.

My Insights:

  • A breakdown does not be bad or hard to take on, it can also be fun.
  • A breakdown comes when I need something to happen or progress to happen in my workplace.
  • I learnt that I don’t need to wait for others to do the work, I can also take responsibility and do a work for which I am not accountable for.

How to create lesson plan

Logeshwari wanted to create a lesson plan for 5th Std on ‘Senses’. So, I gave a presentation to our team on how to create a lesson plan which I learned from the D.El.Ed course which I am attending.

Lesson Plan:

lesson plan is a teacher’s detailed description of the course of instruction for a lesson. A lesson plan can be for a daily class or for a whole chapter.

 A daily lesson plan is developed by a teacher to guide class learning.

A lesson plan is the teacher’s guide for running a particular lesson, and it includes the goal (what the students are supposed to learn), how the goal will be reached (the method, procedure) and a way of measuring how well the goal was reached test, worksheet, homework etc.)

For each steps I gave them an example from a lesson plan which I had created. Then we discussed about the ‘senses in human’ and gave examples for each step to create a lesson plan. I enjoyed giving presentation where we had more interaction between each other.

Lesson Plan 

requirements.txt

Any application typically has a set of dependencies that are required for that application to work. The requirements file is a way to specify and install specific set of package dependencies at once.

Use pip’s freeze command to generate a requirements.txt file for your project:

In the terminal type:

pip freeze

If you save this in requirements.txt,

pip freeze > requirements.txt

then you can install the dependencies using.

pip install -r requirements.txt

Priyan the Tailoring Bird:

The 4th grade were studying a lesson called “A busy Month” a letter written by Gijubhai. In that he would talk about many Indian birds. In the class we discussed about the birds which they have seen. While in the discussion we were discussing about nest and how they are made. Each bird makes its nest differently. So, to do a hands on activity, I asked them to go out of the class like a bird and find any material with which they can build a nest. Everyone were excited and they ran out in search of the materials for their nest. They collected some twigs,hay,leaves. Priyan was able to make a tailoring birds nest out of the leaves,hay and thread he found outside. He was making the nest even in the break time. While he was doing the nest Nithish from 3rd grade came and helped him.

After,Priyan sharing his nest model in the assembly Harish,Aasish and Elanchezhiyan made a nest model of a weaver bird.

The Microscopic Inventor:

As the children were preparing their project for Sir.C.V.Raman contest. Kabilan from 9th grade can to me and asked to me if there were any laser lights he could use. I showed him were the lights were. I asked him “what are you going to do with it?”. He replied “I am going to build a microscope with it”. I was curious about how he is going to build and microscope with it. I thought it is going to be complicated to do it. So , I decided to help him with Bala,Hemasundar(9th grade). He just took the lens which he got from the laser light and placed it on top of the camera on the cellphone and thats all! The microscope is done. To test, first we placed a leaf on the lens and saw the microscopic image on the phone. Next we saw a spider skeleton,flower.. I was inspired on how we can build a microscope using a lens from the laser. We had a lot of fun.

Leadership Programme for the 7th and 8th Graders:

Leadership programme for the 7th and 8th graders was conducted at STEMland ISMART classroom,Udavi.

The programme was conducted Mondays over five weeks. Ahmed,Bridget and Helena were the resource persons. The STEMland AAD team were as PC’s. The following tools were presented to the children.

1. Stand

2. Fear.

3. Background Conversation and Deep Listening.

4. Four Profiles.

5. System Principles.

6. Watched the video of “Story of Stuff” to understand systems.

On the first day we began with ground rules which must be followed during the workshop. After the presentation of each tool, the children were called up to share their insights. A few of the children went and shared their insights. The insights were processed by Ahmed.

Once the programme was completed Sundar had created the triad list. The list was shared with the children and instructions where given on how the triad should be conducted.
