Bat Observation - The steps that I followed to observe and study Bats

Welcome back , once again .

  This time I share with you some info on Bats . Wildlife and Bat-Lovers , Read this blog-post !

My Dad gave me an idea to write this blog... So I thought it was worth sharing ....

Many people consider bats are bad . This is such a misfortune for children that these days they can not see these creatures . Bats are harmless animals but only bite when they are in harm . Considering this , I had a Holiday Homework and even making it a hobby for quite some days ,  I used to go out in the night or the late evenings to a bunch of trees near my home in Tumkur .  I observed and studied them as per the protocols I had made ; -

1 . Keep yourself safe
2 . Please take a flashlight with you
3 . Please accompany to the place with elders [ Above 18 ]
4 . Wear full arm clothes
5 . Do NOT and for any reason get in contact with Bats . They may or may not bite you
6 . Do not go to places such as deep , smelly caves or huge underground caves near waterfalls just to
     study bats
7 . Please make sure you are fully covered .
8 . Don't disturb the Bats , Sometimes to defend themselves , they may drop ' BAT GUANO ' *

BAT GUANO - Bat poop or Bat droppings .

The most important points :-
2There is another danger , but lesser known . People say (and scientifically proven) that Bats
      carry and one that is not as easy to avoid, is histoplasmosis, a disease you can get from   
      exposure to bat guano .
3 .  Most of them say that bats carry Rabies , although it is true , only certain bats carry them .   
      But , be careful . You can never observe bats eye-to-eye !

 These were some of the protocols I followed . IF you guys follow these protocols and observe and study Bats , may it be for your projects or your interest in Bats , you will enjoy it ! 

Enjoy the blog-post and please do comment...

Swachch Baharat Power Presentation

It is interesting to note the importance given for "Swachch Baharat" andolan - a government initiation taken by our PM, Sri. Narendra Modi and it is good to see lots of people are taking serious note of it and actively participating in it voluntarily as individual or as team. As a part of  creating awareness in our school, I was asked by a teacher to prepare a a power point presentation, which I thought worth of sharing ...

Metals are good conductors of electricity....

We had a science expo in our school. The topic of the project assigned this time was "Metals are good conductors of electricity". To present this,  I  used  a small  heavy battery,  a small bulb and small wires...

I connected one end of each wire to the screws on the base of the light bulb holder.  Free end of one wire to the negative ("-") end of the battery  and  the other wire to the positive ("+") end of the battery are also connected. As battery is an electrochemical cell,  it act as energy source. The  bulb lights up because the conductor completes  the circuit and electricity flows from the battery to the bulb and back to the battery.  

As wires are made  up  of  metals,   electrons  flows  across  the  metal   from  one  wire  to the other. Thus we can conclude that, metallic wire completed the circuit,  the  bulb lights up and hence  are conductors, which conduct electricity....

Though this is the simple experiment, I enjoyed friend Harshada explained her part i.e., "metals are conductors of heat". We did explain other metal properties like lustrous, ductility, malleability and sonorus with examples...

Looking forward to share few more,  as and when I find interesting things...

Water Treatment Project - A science expo in my School....

Wel come to my blog.. 

I wrote a small blog post @Life at Dharwad (blog by Sri.Siddesh Uncle) about my school. I thank Siddesh uncle for the encouragement.. I  am thankful to my dad for creating this blog for me. I 

This is my first blog post...

We had a science expo in my school. The topic of the project assigned this time was "Water Treatment Project". I searched internet for any models, though there were a few, it was difficult for me to get the items/materials required for the project. I took the help of my dad (who teaches Engg., Chemistry, in an Engg., college), he guided with a simple project. My grand father  bought the items and helped us to assemble the same.



Screening is first stage of the waste water domestic treatment process. Screening removes floating objects like, diapers, nappies, sanitary items, cotton buds, face wipes and even broken bottles, bottle tops, plastics and rags that may block or damage equipment.  Special equipment is also used to remove grit that gets washed into the sewer. A RCC tank/Chamber is used to remove silt and grit.


This involve the separation of organic solid matter (or human waste) from the waste water/domestic. This is done by putting the waste water into large settlement tanks for the solids to sink to the bottom of the tank. The settled solids are called ‘sludge. If settleable impurities are not removed easily, potash alum will be added and the forced precipitation leads to the  settlement of heavy impurities. At the bottom of these circular tanks, large scrappers continuously scrape the floor of the tank and push the sludge towards the center where it is pumped away for further treatment. The rest of the water is then moved to the Secondary treatment.


The water, at this stage is put into large rectangular tanks. These are called aeration lanes/tanks. Air is pumped into the water to encourage aerobic bacteria to breakdown the tiny bits of sludge/organic impurities into CO2, water, nitrites, sulphates, phosphates that escaped the sludge scrapping process.


Next the ‘almost’ treated waste water/domestic  is passed through a settlement tank. Here, more sludge is formed at the bottom of the tank from the settling of the bacterial action. Again, the sludge is scrapped and collected for treatment. The water at this stage is almost free from harmless substances and chemicals. The water is allowed to flow over a wall where it is filtered through a bed of sand to remove any additional particles. Final treatment like disinfection with chlorine gas treatment/chloramine/UV/ozonolysis leads to water free from pathogenic bacterii and finally the water is  sent to a storage tank. 

In case of domestic treatment secondary treatment is not needed, as water will be free from organic/in organic impurities...
The filtered water is then released into the river.

A sense of curiosity is nature’s original school of education...

Curiosity is the engine of intellectual achievement — it’s what drives us to keep learning, keep trying, keep pushing forward. But how does one generate curiosity, in oneself or others?

Curiosity arises,  “when attention becomes focused on a gap in one’s knowledge. Such information gaps produce the feeling of deprivation labeled curiosity. The curious individual is motivated to obtain the missing information to reduce or eliminate the feeling of deprivation.” Loewenstein’s theory helps explain why curiosity is such a potent motivator: it’s not only a mental state but also an emotion, a powerful feeling that impels us forward until we find the information that will fill in the gap in our knowledge... Dr.Umesh I have created, this blog for my son Master.Vinayak, so that, he can satisfy his curiosity, which I feel  is one of the greatest sources of happiness in life. 

Several quotes encouraged me to do this.....

Curiosity is the very basis of education and knowledge... Curiosity will conquer fear even more than bravery will...Free curiosity is of more value than harsh discipline....Curiosity is, in great and generous minds, the first passion and the last...
