Concept of Wet Laboratory Chemical Science Experiments for Visually Challenged

Everyone eats food, drinks water, juices, puts up clothes on the body, cleans teethes with toothpaste, washes

clothes with detergents, takes bath with soaps, adds sugar to tea or milk and salts noted as sodium chloride

to food items. Almost everyone cooks food in kitchen using cooking gas and everyone senses what is hot

and what is cold where the hot or cold concepts constitute an interesting science noted as the

thermodynamics. The water and cooking gas are taken in bucket of solid walls and gas cylinder of solid

walls respectively. The above mentioned science is sufficient to provide a supporting ground to visually

challenge to understand the science and technology being applied in daily use. The food, juice, gas and

others give energy to body and noted as energy sources. The energy sources are molecules made up of

atoms which are attached through bonds. The clothes do not harm body and are noted as biocompatible

materials while the heat and cold harm body and are noted as non-biocompatible properties. Thus the

everyday applications and experiments with the materials do develop the concept of science and

technology. Thereby, the concepts, realization, experience of science in life of visually challenged through

such experiments could be extended to advance their science learning through unbelievable and unthinkable

inventions. The most practical and applied areas which are very familiar to visually challenged do generate

faith in science and encourage to let them know more and more about several sciences and technological

systems. Currently, the visually challenged are not only well aware about recent happenings but are also

potential users of ICT (information communication technology) and computer based other techniques.

Though the ICT gadgets are most safe and noted as dry lab concept (DLC) as the computer key is made upof most biocompatible polymer materials which do not harm the body of the user. The DLC is nice but

there is an urgent need to develop the gadgets to teach science and technology to visually challenge, at least

at a conceptual level. It could be in a form of wet lab concept (WLC) such as dealing with the testing a

quality of water, shampoos and syrups. When the science has become a tool to resolve almost all issues

then why does not the science exposure be given to visually challenge. Of course, the visually challenged

need some real use science through some connecting and interacting interface such as sound that could

connect them to science equipment of wet laboratories for doing some real experiments using the chemicals

and apparatus. For examples, the solubility determination, understanding of dissolution, role of solute and

solvent in ideal and real mixtures with high industrial potential such as herbal, ionic molecular liquid

mixtures. Knitting wheat, maize, barley, oat and other flours with the water and salt is noted as interesting

and daily use formulation for cooking bread and other food items. Similarly the concept of formulations of

industrial mixtures could be taught them excellently and convincingly. Every day, they use toothpaste,

soaps and detergents, oils, clothes, plastic made items. These are chemical products and their quality

matters a lot, therefore such examples manifold the science learning and picking up confidence. Through

these items, these people find science very close to them and in fact consider themselves as frequent user of

scientific processes and products. There are uncountable numbers of the well-known, experienced, tested,


19/23

Page 19 of 23

reliable and fearless points which constitute a concept of daily use sciences in life. Interestingly, there are

several food items which make them take the science and technology as inevitable foundation of the life.

For example, the rice noted as carbohydrate (source of energy for sustaining life), pulses as source of

proteins that repair tissues of body, salts that catalyzes the food molecules such as carbohydrates, proteins

enzymes and others. Also the oils and fats are the most significant food items to sustain life. The salts are

most helpful tools for food processing and digestion which also maintain ionic balance in the body. The

sugar which produces vital energy and is widely used.

Taste as potential test for understanding concept of molecular structure:

The tastes of salt (NaCl) and sugar will define a role of molecular structures that induce specific functions

of the materials. The addition of sugar and salts to the water defines solubility and physicochemical

properties due to their different structures and constituents. Even chemical bonds between atoms in

different molecular structures also vibrate or oscillate with specific frequencies. If these frequencies are

trapped and converted into the sound then such conversion could be an asset to visually challenge to learn

the hardcore chemistry or the materials science. Of course, there are different types of the sounds being

experienced in daily life. Such experiences also define optics and frequency of different sources such as car,

harmonium, flute playing, fighting, storms, raining, talking, weeping, and running tractor on rods and many

others let them know the outside world. Thus the sounds distinguish good mood through the sound of

laughing and bad mood or sorrow through the sound of weeping or crying. Also by putting many clothes on

the body in winter defines a concept insulating materials where the clothes act as insulators of temperature.Non-soluble materials as clothes are washed several times but remain un-dissolved in the detergents and the

water solutions. The detergents are dissolved in the water and their solutions wash or drain out the dust

particles. However, the detergents which are used to wash the clothes are solubilized in the water and wash

the clothes nicely. Such experiences in daily life could develop a concept that the detergents modify the

physicochemical properties of the solvents. The concept also defines that the solutions and solvents

properties are different due to different additive of detergents. The dissolution of the detergents in a very

smaller amount in comparison to the water makes them feel a difference in amounts of the detergents and

the water as the solvent. Thus the detergents are referred to as solute and the water in bucket as the solvent.

The mixtures are obtained on mixing the solute and solvent together and are also noted as the solutions.

Since the water as solvent is used in dissolving the detergents then the resultants mixtures are noted as

aqueous mixtures. The oil which used in daily life is organic solvent or the molecules. The clothes are

degradable and the plastic is non-degradable materials.

Certificate Course: A certificate course in analytical techniques for visually challenged

peopleThis certificate course is aimed to enable visually challenged people for learning basics of chemical

sciences through certain experiments conducted with visionmeter. The viscous flow time (VFT) data


20/23

Page 20 of 23

collected with visionmeter of different mixtures such as ionic, molecular, surfactants, hydrophilic and

hydrophobic molecules such as proteins and others would explain science of industrial formulations. The

course will instill confidence, reorient their minds for science learning and skill for analytical sciences in

academics, research and development. The will open new employment opportunities for them in fields of

formulation and quality testing of daily use products. The Mansingh Visionmeter is indigenously developed

equipment and it has alignment of the VFT with the electronic communication for a response of the

molecules taken in samples. The concept of visionmeter is noted as an excellent innovative idea which

would provide an immense self-confidence in the visually challenged with moderately educated disabled

persons to make them capable and self-reliant. Such awareness and initiatives towards science and

technology will make visually challenged people more competitive with the sighted people in a material

world. The skill which will be achieved through this course would create analytical minds that could be

considered as an example in science disciplines for monitoring the quality assurance and control of daily

use products. Thus, in nutshell the newly devised course curriculum would give new life and direction to

the visually challenged people. Details of course contents are attached here with.

About the course: The major objectives of the programme are to:

Provide comprehensive knowledge to the learners on analytical techniques in chemical sciences

laboratory.

Enable the learners to do quality assessment of daily used commodities.

Generate science and technology awareness, and strengthen their minds to be competitive in

material world. Such efforts and participation in analytical testing will prevent the adulteration of

unwanted materials in daily use items such as food products, soaps and detergents and improve

clinical practices.

Create greater scientific awareness about analytical chemistry.

Incorporate idea dreaming and driving attitude and sharpen professional skills.

Fundamental breakthrough for visually challenged to elevate quality of life

The visionmeter is a Scientific Eye for visionless or visually challenged, it works on Molionic Electrostatics

(ME) incorporating IMA and IME, transforming and translating into acoustic dimensions such as sound,

frequency, volume and others. The visionmeter is fabulous science in modern day time to eradicate miseriesof most needy, talented and suffering section of society. It has opened new era, dimension, option of

challenge to think high and face odds, look ahead and sky-high for best survival with new fundamental


21/23

Page 21 of 23

message of Progressive Survival ofthe Struggle (PSS) against century old Survival of the Fittest. The

PSS is leading rather than existing. Agony and atrocities being associated with visually challenged must be

routed out at the earliest as they are gifted with powerful memory, reasoning, deciding wisdom, dreaming

and strong articulating faculties:

The visually challenged have natural talent and potential to accept and implement creative devices

to sustain under all odds. Partly the visionmeter could resolve their hardship and elevate quality of

life and to feel equal and similar to sighted people in daily routines.

The visually challenged are not brought to scientific streams even when they have hidden talent and

keen desire for learning, listening and offering significant contributions to such fields where

dreaming ideas is foundation of success.

If infrastructure and opportunities are given to them for thinking and working on scientific projects,

they can become most competent and could contribute a lot more to society to excel and explore

many more areas and frontiers as asset to the society.

Presently in time of science and technology no infrastructure is given to them except ICT

applications and their talent is not being captured for scientific leaning.

Therefore, there is an urgent need to develop facilities from a most basic levels and visionmeter is

landmark in this direction.

The visionmeter could act as a significant catalyst for channelizing, igniting and triggering their

minds to explore something new if it is given to them for learning and using for QC and QA of

modern day materials.

The visually challenged could generate new applications and ample opportunities of employments

with visionmeter technology. As the visionmeter addresses equality issue and opens new doors to

experimental sciences. The visually challenged are the real dreamers but surprisingly are

marginalized in society. The visionmeter is very useful because it is simple and based on acoustic

concept and automatic in working. The PC could also be attached for further facilitation.

It not only teaches to measure fluid dynamics monitored by hydrogen bonding, ionic and molecular

interactions, unfolding of macromolecules, viscosity but also several other concepts of chemistry

such as how to distinguish between monobasic, dibasic and tribasic acids or salts along valences.

The water binding, drug loading, reacting and interacting features of the molecules.

Fundamentally, it could be an asset to teach chemical kinetics, thermodynamics, hydrolysis,

adsorption, solubility and solubilization, and lot more.

The visually challenged can do QC of detergents, soaps, sol gels, syrups, food items, drinks, dyes,

oils, petroleum and polymers along hydrogen bonding, dimmerization and aggregation etc. which

are depicted over fluid profile of mixtures.

The visionmeter is easy to handle with safe and closed electronic circuits and electrical for operation

and acoustics. It is fascinating and inspiring, is patented with Govt. of India and calibrated with

Survismeter, a NPL standards. It aims for new gateways and ample employment to especially

visually challenged women to become self-dependent.

Brief outline for operation

As it is aimed to induce, introduce and teach science and technology for the visually challenged, a twelve

tier training modules (TTTM) are available for its best use and developing skill.

TTTM: 1. Introduction and primary awareness of visionmeter. 2. Scientific concepts and configurations. 3.

Working and fundamentals of circuitry sensory for experiments. 4. ME with IMA and IME. 5. Handling

and experimenting skills. 6. Data collection and significance. 7. Accuracy and precision in data. 8. Data

simulation and analysis. 9. Experimental and standard errors analysis. 10. Quality control. 11. Quality

formulation. 12. Simulated sciences for employments.

For developing vibrant hopes and happy moments in life of visually challenged

Sharing science knowledge, engaging in learning process and even talking to them

make them feel equal and important in day today working.

They need special scientific assistance for doing calculation and processing

experimental data for concluding useful information out of their experimental

learning.Formulating simple learning and experiments putting their body parts in different

motions and directions are most effective mode for teaching them science.

For example, spreading their hands in opposite direction with respect to head the

structure of triatomic molecular structure such as CO2, NH3, SO3 and others are taught

them.
