CUBE Chatshaala Summary (02 July 2026)
Today’s Learning Journey: From University Subjects to the Science of Light and Colours 
“Science is not about memorizing facts; it is about understanding the story behind every fact.”
Today’s Chatshaala began with an inspiring interaction with @Sailekshmi a B.Sc. Zoology (5th Semester) student from Kerala University. She introduced us to the subjects she is studying this semester, including Developmental Biology, Animal Physiology, Microbiology & Immunology, Ecology and Disaster Management, Fisheries Science Part III, and the Skill Enhancement Course (Vermiculture and Vermicomposting).
This discussion helped us understand how Zoology is not limited to the study of animals alone. It beautifully connects physiology, microbiology, ecology, fisheries, and environmental science, giving students a broader perspective on life sciences.
Learning About Different Universities and Academic Pathways
We then learned about Elphinstone College, a constituent college under Homi Bhabha State University (HBSU). Our fellow CUBists @Aarya and @manali , who are currently pursuing their B.Sc. Biotechnology (3rd Semester), shared insights into their curriculum, including Microbiology and other biotechnology subjects.
It was inspiring to see how students from different universities come together on one platform to learn from each other. This reminded us that while courses and universities may differ, curiosity and scientific thinking unite all learners.
“Different universities may teach different subjects, but the language of science is the same—curiosity.”
Understanding the Difference Between BARC and HBCSE
Another important discussion focused on two prestigious institutions that many students often confuse.
Bhabha Atomic Research Centre (BARC) is dedicated to advanced scientific research, particularly in nuclear science, medicine, agriculture, and technology.
Homi Bhabha Centre for Science Education (HBCSE) focuses on science education, teacher training, Olympiads, and nurturing scientific thinking among students.
Although both institutions are named after Dr. Homi Bhabha, their purposes are different. One advances scientific research, while the other strengthens science education.
Beyond Memorization: Why Do Students Find Science Difficult?
“Knowing the answer is good. Understanding the reason is even better.”
One of the most meaningful discussions today was not just about scientific instruments but about how we learn science.
Many students can easily memorize definitions, formulas, and instrument names, but they often struggle to explain why something happens or how it works. This is because we sometimes focus more on remembering than on understanding.
For example, during today’s discussion, some students were confused between Calorimeter and Colorimeter.
Instead of simply memorizing the names, we should ask ourselves:
Why are their names so similar?
What does each instrument actually measure?
Why does one measure heat while the other measures colour?
When we understand the meaning behind the words, the confusion disappears naturally.
Calorimeter → Measures Heat Energy
Colorimeter → Measures Colour Intensity to determine concentration
Only one letter is different, but their functions are completely different.
Science becomes easier when we stop asking “What should I memorize?” and start asking “Why does this happen?”
“Memorization may help us pass an examination, but understanding helps us solve real-life problems.”
Understanding the Spectrophotometer Through Everyday Examples
We then learned about the Spectrophotometer, an instrument that measures how much light is absorbed by a solution at different wavelengths.
Rather than only remembering its definition, we tried to understand the science behind it.
Example 1
Water + Sugar
The solution remains colourless because dissolved sugar does not absorb visible light.
Example 2
Water + Copper Sulphate
The solution appears blue because Cu²⁺ ions absorb certain wavelengths of visible light while transmitting blue light.
This naturally raised another question.
If two solutions have different colours, can we measure that difference scientifically?
Yes!
Both the Colorimeter and the Spectrophotometer measure light absorption, which helps scientists determine the concentration of substances in a solution.
“Light carries information. Scientists simply learn how to read it.”
Spectrum: Understanding Light Through a Rainbow
One of the simplest and most beautiful examples of a spectrum is the rainbow.
When white sunlight passes through tiny water droplets, it bends and separates into different colours because each colour has a different wavelength.
This forms the visible spectrum:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Instead of only memorizing VIBGYOR, today’s discussion encouraged us to ask:
Why does white light split into different colours?
Why does each colour bend differently?
Why is a rainbow considered a natural spectrum?
These questions help us understand the concept much more deeply than simply remembering the sequence of colours.
“Every rainbow is nature’s way of teaching us the science of light.”
Reflection: Thinking Like a Scientist
Today’s Chatshaala reminded us that science is much more than definitions and diagrams.
A scientist does not stop after learning what happens.
A scientist keeps asking:
Why does it happen?
How does it happen?
Can I prove it with evidence?
These questions transform learning into discovery.
Science becomes meaningful only when we develop the habit of observing carefully, asking thoughtful questions, and seeking logical explanations.
“Curiosity is the first step, questioning is the second, and understanding is the destination.”
TINKE Moments (Things I Never Knew Earlier!)
I never knew that Calorimeter and Colorimeter sound similar but perform completely different functions.
I never knew that understanding the meaning behind scientific terms is much more effective than memorizing them.
I never knew that light absorption can help determine the concentration of a solution.
I never knew why copper sulphate solution appears blue, while sugar solution remains colourless.
I never knew that a rainbow is the best natural example of the visible spectrum.
I never realized that the biggest challenge in learning science is not difficult concepts, but studying without asking questions.
Final Takeaway
“Science begins the moment we stop saying ‘I know’ and start asking ‘Why?’”
Today’s Chatshaala was not just about learning scientific instruments and concepts. It was about developing a scientific mindset. The session inspired us to move beyond rote learning, think critically, ask meaningful questions, and understand the science behind everyday observations. This approach makes learning more enjoyable, memorable, and meaningful.
