The third day of the
INSPIRE Science Internship camp started with the interactive session which was
held on learning mathematics with Prof. S.N. Chibber, retired Principal from
Directorate of Education, and Secretary, Delhi Associate of Mathematics
teachers, a resource person with NCERT, SCERT and CBSE. He shared his vast
experience of teaching Mathematics with the students and also taught tricks to
make classroom teaching interesting. He gave a very interesting talk on the
aspects of Mathematics in day to day life using very simple rules of addition,
subtraction, multiplication and division. Through his educative lectures
students became familiar with the difference in external appearance of glasses
and their volumes which are being used in homes and hotels .Using very simple
techniques he explained differential and integration equations, calculations of
the largest number and the smallest number divisible by 2,3,4,5,6,8,9. He also
explained very lucidly the determination of complex figure areas by simple
squaring and addition of numbers. His lecture made students very keen to learn
mathematics, develop interest and apply the subject in every aspect of life. He
also correlated mathematics with biological sciences giving very simple
examples of medicinal dose taken by patients.
This was followed by
lecture of Prof K.K. Bhasin, Professor in the Department of Chemistry and
Centre of Advanced Studies in Chemistry, Punjab University, and Fellow of the
National Academy of Sciences, India. He has seminal contributions to the
Chemistry include that of Organosulphur, Selenium and Tellurium compounds. Dr.
Bhasin is a recipient of prestigious Commonwealth Fellowship Award, Science
Research Council fellowship (U.K) and DAAD fellowship (Germany). He gave a
lecture on “Civilization: Man’s relationship with Materials” which was based on
the application of materialistic chemistry in the society that has ingrained
well and is overlooked or under appreciated. He explained with an example of
lead pencil which has been used since a long time and is a part of our
education, but had been rarely thought of as such what material has been used
to prepare it? How much concentration of lead may be present in it?
Then he explained periodic
table which includes 118 elements out of which two has not yet been discovered.
He stated that
generally all elements are named after the death of scientists but one element
is named when the scientist was alive and that is Seaborg with atomic mass 106.
Grignard Reagent (RMgX) was named after scientist Victor Grignard and has been
used to prepare a number of compounds. He then moved to the explanation of
another compound NH4NO3 which is a very unique molecule,
also used as fertilizer and a highly hygroscopic compound. He related the
hygroscopic nature with a story in which a large amount of NH4NO3
was being shipped to Texas city. Due to hygroscopic nature the compound
was coated with wax. Someone in the ship dropped a burnt cigarette near the NH4NO3
box and it caught fire which resulted in the death of about 500 people.
With this story he explained the reaction between NH4NO3 and
hydrocarbon fuel which forms the basis of crude bombs that had been prepared in
Russia and also used during the blasts of Bombay and Bihar. He explained the
Redox reactions by the ionic nature of compound. Then he gave introduction
about the Memory metal ‘NINITOL (Nickel Titanium Naval Ordinance Laboratory)’ a
fatigue resistant alloy for missile nose and that its discovery was the best
example of Serendipity (discovery by chance). He included small explanatory
notes on Reinforced cement as a revolution in modern architecture and the
introduction of Chromium and Nickel as impurity to develop photogrey glasses.
He also explained chemistry of soda azide (NaN3), a versatile
compound, and shock sensitive and because of the property it finds its use in
air bags, white wash and lime light.
The students solved
their queries such as the working of soda azide by chemical reactions and also
about the comparison of white wash and distemper to be used in houses. Bhasin
Sir satisfactorily solved the queries of students.
The students had a
break after the session for tea.
The next section
continued with the lecture by Dr. Sampat Kumar Tandon, Pro-Vice-Chancellor,
University of Delhi (2005 onwards), on the topic ‘Science- A Global Enterprise’
Dr. Sampat has pioneering contributions in physical stratigraphy and
sedimentology, geomorphology and quaternary geology with reference to the
Indian regions. His presentation was on the topic of “Exploration in Earth and
Planetary Sciences”. He explained about the rovers and satellites that have
been launched and as well as in process of launching to detect the traces of
life on planet Mars. He explained Martian sedimentology including soil sciences
and water traces. Through the rover such as sojourner , spirit/ opportunity
and curiosity launched on mars since 2000, the scientific
agencies such as NASA has been able to detect the chances of life on Mars
through the material brought by them. He also explained the configuration of
the rovers which includes number of instruments almost equal to that of big
machine, 17cameras and much more. He gave a diagram to give the overview about
the entry, descent and landing of rovers onto mars. He also explained the
unpooling of electrical and communication cables before landing of rovers on
the planet. He also briefly discussed about the Mars Orbiter Mission of India,
also called Mangalyaan, a space probe orbiting Mars since 24 September 2014. It
was launched on 5 November 2013 by the Indian Space Research Organisation. He
explained the basic differences between the NASA’S Maven and India’s Mangalyaan
Mars Orbital mission (MOM) which include the different payloads
packages, as befitting their separate objectives. MOM's instruments are mainstream, broad
spectrum, and intended to give ISRO experience at measuring different types of
planetary data ranging from atmospheric to surface morphology. MAVEN's
instruments are all focused on upper atmosphere and are cutting edge, measuring
to greater limits, sensitivity, and accuracy than previous missions.
He also motivated the
students with the biographies of various Indian scientists whose research had
been published in the journal ‘Nature’ and ‘Science’.
Students asked various
questions regarding the time limit of landing rovers on any planet, difference
between rovers and probes and of what material the tyres of rovers are made.
FORENSIC
SESSION:
The laboratory session
included the forensic sciences section in Chemistry Lab of KIIT college of
Engineering where Ms. Kanudeep Kaur from Sri Guru Tegh Bahadur Khalsa College
of University of Delhi elucidated about the development of finger prints on
papers using Silver nitrate solution and Ninhydrin solutions. She started with
the types of markings on hand and that there are three types of fingerprints
i.e. arches, loops and whorls which are different for each and every
individual. There are 85 characters on fingertip out of which 8 are to be
detected to identify a person. She gave a brief lecture regarding the obtaining
of finger prints on the paper and other uneven surfaces. Using charcoal and
iodine crystals she gave a live demonstration about the developing of finger
prints. The students found the lab session very interactive and were keen to
develop their own fingerprints. All the students were given some graphics as to
categorize the various demarcations in a fingerprint.
CULTURAL
EVENING:
After this the students
enjoyed cultural evening in which the students of KIIT College of Engineering
presented dance. The participants had an enthralling response towards the
cultural programme. The evening was a huge success, filled with music, dancing,
crafts, food & drink.
Games such as chess, carom
board, badminton were held where children proudly participated. Everyone
enjoyed taking part in drumming workshops, which provided a perfect background
beat. A troupe of dancers showed off their steps. Craft stalls enabled children
to make friendship bracelets and choose a bindi to wear. Students enjoyed a lot
with the hip-hop performances and bhangra dance. Students among the
participants also participated in singing where they sung old songs of Kishore
Kumar, Md. Rafi as well as songs of KK and Honey Singh. Some of them also acted
in the mimicry event where they acted the personalities as Devanand, Shahrukh
Khan and many other heroes. Food and drink from around the world was donated
and available to try, including various fruits and juices, pavlova, bhajis,
samosas and Caribbean snacks, to name but a few!
