Day 6: Biology Hands Activity

Day 6 : 29th april 2017 Report by Gaganashri.

     Today was an interesting and informative class. We all were eagerly waiting as we were informed by our teacher that today would be 'hands on activity' session.
   Before starting that session, Kamala mam gave us the glimpse of details regarding the field visits which will be held on the coming days. Although we were thrilled to know more, we moved on to welcome today's resource person Prof. Ramesh [HOD of Zoology] and Vishwanath [Vice principal of National College, Basavanagudi].
  We were soon divided into several groups and moved to Zoology lab. It was Prof.Ramesh 's lecture which allowed us to get into the world of 'BLOOD'. We learnt about the discovery of ABO blood. It is believed that ABO blood was discovered by Karl Landsteiner in 1901.

  We got to know many things. I have tried to summarise the lecture using the following sub heads:
• Discovery of blood
• Composition of blood
• Functions of blood which includes      Transportation, Protection, Regulation etc.
• Contents of blood
• Staining of blood cells i.e. Wright's stain
• Blood transfusion
• Cardiovascular system
• Lymphatic system
• Circulatory system
• Formed elements
• Erythrocytes, Leukocytes
• Blood group inheritance
• Functions of Lymphocytes
• Identification of blood group
• Rh grouping system
• Blood cell compatibility
   After covering all of the above topics, it was time to perform an activity which helped us to identify our blood group. Prof. Ramesh taught us to perform this activity. He also performed the same activity and identified the correct blood group of one of my friend. We all were actually surprised to know that our blood group could be identified in such a simple way.
  Then, we also got to know about some rear blood groups like Bombay blood, its disorders, OH blood group and we also got to know how the name Bombay blood was actually originated.
   After this, we were into 'Zoology museum'. We got a great opportunity to look into many specimens which included foetus, embryo, octopus, molluscs, different arthropods, amphibians and models of skeleton, human brain, sheep brain etc.
  We were soon shifted into Botany lab. This class was taken by Mr. Vishwanath. We were very happy to hear his lecture as he explained us in the most simple and detailed way. In his class we learnt about plant anatomy, monocot and dicot plant, xylem, phloem etc. We were even taught how to identify whether the given plant has monocot or dicot plant. He explained this with a very interesting and simple lab activity. According to that experiment, we should observe the temporary mount of a stem under microscope. If the vascular tissues are arranged radially, it indicates that the given stem is dicot stem. If the vascular tissues are scattered, it indicates that the stem belongs to monocot plant.
    This is just a small summary that i have tried to note it down. But, science is a very vast subject which includes observation, analysation, experimentation etc.
   However, it is rightly said by Oscar Wilde that "Success is a science; if you have the conditions, you get the result".

Day 5: Visit to JNCASR

This is GROUP 5 from the Bangalore science forum summer school(2017).Our report is regarding the field visit to JAWAHARALAL NEHRU CENTRE FOR ADVANCED SCIENTIFIC RESEARCH.It is a multidisciplinary research institute situated in Jakkur, a locality in the  north of Bangalore, India. It is relatively young yet well-known around the Globe. This Centre was established in 1989 by the Department of Science and Technology of the Government of India, to mark the birth centenary of Pandit Jawaharlal Nehru. Researchers at the Centre are divided into nine units: Chemistry and Physics of Materials, Educational Technology, Engineering Mechanics, Evolutionary and Integrative Biology, Geo-dynamics, Molecular Biology and Genetics, New Chemistry, Neuroscience, Theoretical Sciences.

We were fortunate enough to get an opportunity  to visit this wonderful institution.This visit was initiated by Dr.Y.C.Kamala ma'am and team.We had to assemble at the college by 7:45AM and departed approximately by 8:30 , we reached the venue by 9:15-30AM. It was a short fuzzy travel by bus.As we got down our buses the sight was completely unusual and very new to us.We were asked to be seated in a hall for the lecture which was given by Chandrabas Narayana. His lecture was about Light and Matter.At the beginning he asked us a few questions like:-
  • What happens when light falls on a material ?
  • Why are sky and sea blue ?
  • How do we see things ?
He briefly explained properties such as reflection,refraction,transmission,luminescence,absorption,inelastic scattering,elastic scattering of light.He explained the Raman Effect discovered by C.V.Raman and his student Krishnan which is the change of wavelength exhibited by some of the radiation scattered in a medium.After the lecture we were taken to the various laboratories present in the research centre. We visited about 8 laboratories and curiously gazed at those equipments present in the labs. The Laboratories which we visited are as follows :-
·         TEM(Transmission Electron Microscope)-It is an electron microscope which is very huge and complicated .It has a capacity to view upto 1.7 Angstrom, this microscope can fetch images by passing electrons through the specimen at high velocities by applying a potential difference from 300-400Kv.
·         SEM(Scanning Electron Microscope)-This microscope was similar to the TEM but could fetch resolutions only upto 60-70nM.We saw images of various specimens including insects,metals,etc.
·         Human Tissue culture -This lab was the place where human tissues were cultured in a sterile environment such that there is no disruption in the growth of tissue .This lab could be entered by very few authorized people and the room was connected to air purifiers such that there is no infection.
·         HIV-AIDS Lab -This Laboratory was mainly designed to find cure for the deadly disease AIDS caused by HIV virus. This lab consisted centrifugal machines ,Incubators, Refrigerators, DNA and Bacterial cells.
·          Dispersion of Light – Here the Raman’s Effect was experimentally proved by a laser and various instruments. Here we could see different wavelenghts of light.
·         FESCM:- Here researchers made various equipments for devices which had to be done in a very sterile environment where even sunlight was filtered through films and the person who entered this lab had to wear a lab suit and had to undergo a sterile shower which would kill all the bacteria on the body.
·         Photo-electronics:- Here we got to know about various gadgets internal display , How it was made and what additions could be done to improve it and what adverse effects these modern gadgets caused our human body.
·         Nano-Particles Lab:- This place was all about Nano-particles and its properties.Each substance at its Nano size had different properties like as everyone know gold is yellow in colour whereas at its nano-liquid state it is brown in colour and this could be engineered to enter our body and the particular part to kill the cancer cells.
These were the laboratories which we visited at Jawaharlal Nehru Centre For Advanced Scientific Research .It was a very interesting tour towards modern science and technology. It lit up our mind and brought enthusiasm towards science and technology.We thank the Bangalore Science Forum for providing us such an opportunity.

Day:4: Mathematics Activity

This is the report of day 4 by group 4-Tushar U and group.

Mrs. Kamala ma'am introduced Dr. Srivatsa. S. K, an expert in the field of electronics. Then Dr. Srivatsa began to interact with the students by first asking them to solve a  few puzzles. Sir then asked the students to solve an anagram. The students could solve both of these in a jiffy. Sir then told us about the topics that he would discuss during the day like electronics,magnetism and fluids. He then told us that one should explain a concept in a small time with simplicity.He showed many quotes of many famous scientists such as Newton, Galileo amd Einstein. 

He said that while approaching science, one should have curiosity, clarity, competence and connectivity. The students were listening to him with rapt attention. Sir said that these approaches had different effects such as observation, experimentation, modelling.  talked about the observations of Galileo Kepler and Rutherford. Sir showed us a very interesting clip, showing what happens when two objects of the same masses are left to fall from the same height in a vacuum chamber. The result was that both the two objects fall down and the same time.  He explained to us the result of the clip.He explained to us the Rutherford's experiment showing the deflection of Alpha particles.

 He then told that we were going to conduct some activities. All of us were excited. The first activity involve the use of a rubber band in which we needed to stretch the rubber band and place it on our lips. We then felt some heat on our lips due to the stretching of the bonds between the carbon atoms in the rubber band which released energy in the form of heat. We then released the stretch rubber bands and placed it on our lips. The observation was that our lips felt cool. 

Sir then spoke about Coulomb's laws. He then spoke about electricity and Magnetism. He then demonstrated an experiment with the help of one of his students. This experiment involved a Tesla coil in which he brought a tubelight close to the Tesla coil and the tube light started to grow immediately. This blew our minds. He then asked us to feel the heat at the tip of the tesla coil one by one. Dr.Srivatsa then demonstrated an experiment which involved a robot which follows a line.Dr.Srivatsa then demonstrated an experiment based on the topic Home Automation in which the switching on and off of the lights in a house can be controlled with the help of a mobile . The intensity of the light could also be controlled with the help of the mobile.

Day 3: Mathematics Ativity

Activity Day 3
Mathematical modelling and solving of quizzes      
Members:-, Amruth gowda, Rohit Raj ,Nikhil, Yogishwar, Trishal, Supriya

 We were introduced to Janavi mam by Kamala Maam. The day was more of a head scratching sessions which involved puzzle solving and also creation of models.

Her class began half an hour later. We decided that instead of having four puzzles (soma’s cube,  loop the loop, creation of dodecahedron  using 12 regular pentagons, and the tower of annoys) we decided to have three of them(soma’s cube, loop the loop, creation of dodecahedron  using 12 regular pentagons.   

At first we began solving soma’s cube. The Soma cube is a solid dissection puzzle invented by Piet Hein in 1936 during a lecture on quantum mechanics conducted by Werner Heisenberg. Mam allowed only ten teams to try out the puzzle and asked the rest if the team to try it later on due to the shortage of time. Even in those teams only 3 or 4 teams were able to complete it within the given time limit of 5 minutes all the teams who were able to solve the puzzle did it within 3 minutes. Then we moved on to the formation of a dodecahedron using 12 regular pentagons. This project was supposed to be an individual project but as many boys had not bought their personal share of 12 A4 size sheets mam made this a group activity. At first mam made us fold the rectangular A4 sized sheet into a regular pentagon by using the technique of origami and not kirigami. After the formation of the 12 regular pentagons mam made us to fix it together to for a dodecagon. This process was a nice one but a little tricky due to the condition she had laid that the flaps that were created during the formation of the regular pentagon must be inserted into the pentagon. A very few teams were able to create a dodecagon. Later mam started to trick our mind by the puzzle of loop the loop. It was simple newspaper quiz which contained a grid and many numbers in the grid with the condition that the number should be surrounded by the same number of line segments and by the end we should create only one closed figure. This puzzle was taught to us as many students were not aware of solving it even though they had seen the puzzle in many newspapers. Later mam told us to create our own loop the loop question. Many of the students did it the hard way (putting the number and then drawing the grid) were as many students did it the smart way (first drawing the grid and then writing the corresponding numbers).

 Later by the time it was 12 o’clock Mr.Sundar  ,a person doing his PhD in the Indian Institute Of Astrophysics,  gave us a small session on black holes. At the beginning he made us visualise the sky in all the past times (the time when Newton was present, the time when Galileo Galilee was present, and the times when we were nomads). Then he told us about the formation of a black hole and why it looked so. There we also discussed a little on the merging of the galaxies and with it the merging of a black hole.Later a question and answer session was done where we were allowed to ask some questions. Many interesting questions came like:-
·        Why can’t a person go as fast as light
·        What happens when an isolated black hole doesn’t get any matter
·        What is the difference between a black hole and a worm hole?

Day 2: Prof.Harish Bhat

Report of day 2 by .G N  Samrudda, Yashwanth,Mukunda M, Bharath, Bhavana

This was the first day after the inauguration day. Today one of the resourceful person Prof. Harish Bhat had come to provide us some resourceful knowledge about science. He gave us a very interesting knowledge about science which showed us that we are nothing in front of many smaller insects. The way of his explanation was to the top. We understood everything very easily which we could not do in our school days. He taught us about ants, termites,grasshoppers, spiders,and many other things. Really it was a very interesting subject which we learnt today. Not only this much he also made us to do many models based on these topics. This models gave us many information which was not known earlier. So in this we thought a lot, enjoyed and worked together as a team and finally finished it. All the 15 groups then came and explained about their own models this helped us a lot to improve our thinking skills and we got to know about our own capability.And the project goes like this:
2.Miniature table
3. Hexabridge
4.Octocam and book pen holder
6.Table and robot
7.water conserving bridge
8.foldable bridge
10.Hexagonal shaped book shelf
12. Octo lamp
13. wheel chair
14. octocam
These were the topics that was presented today... Everything was fine and good here but the only problem was about time.So we conclude that we enjoyed a lot and learnt many things and would like to continue.

Inauguration of 50th Annual Summer School in Science 2017

This year is the 50th year of Annual Summer School in Science conducted by Bangalore Science Forum. The report of the day's activity by group 1,  penned by Shashank HR and team.

BSF day one report by group 1 

The program was held in the Dr H.N . Multimedia hall , The National college, Basavanagudi, Bangalore .
We were very excited about the camp and about the activities and lectures. At 9.30 AM the program began introduction to the Bangalore Science Forum Summer School by Dr.Y.C.Kamala which included the following key points:
 The BSF was started in the year 1962. 
2- the founder of BSF is LATE    PADMABHUSHANA Dr . H . NARASIMHAIAH
3- The Current President of BSF is Dr . A.H Rama Rao

Dr. H.N was always attending the music festival at Fort High school grounds in Bangalore. When he  came to know that there was no one month long festival for science, he decided  to start annual science festival on the month of July, & they decided to conduct a summer school in Science for students in Class for 7th & 10th standard students in the month of April and May.

When we heard about the anecdotes of many great people who came to this place we felt we are extremely lucky to be a part of the camp, that too in its golden Jubilee celebrations.

The guest speaker of the day was Smt.Sumangala Mummigatti , Program executive, in charge head at FM rainbow 101.3 FM Air Bangalore and national awardee for science communication.
We came to know  about the importance of science & why we have to learn science, its avenues, advantages and merits.
The Presidential Address was given by Prof. Nagaraj Reddy ,Retd. professor of Psychology and Secretary of BangaloreScience Forum. He gave valuable insights about studying science and distinguishing myth and reality. 

And then Kamala Mam introduced another 3 coordinator's of BSF , they are
1- Lakshmi Mam
2- Sundar Sir
3- Jahnavi Mam

After all this Jahnavi Mam made us a 15 group's of 5 members, & Lakshmi Mam gave the instructions about how the camp will function. We received feedback form from the Jahnavi Mam, we have to write our feedback in that form in the scale of 1 is the lowest & 5 is the highest .and they also gave a glimpse about the field visits
