What a Renaissance artist's hidden chemistry experiments can teach modern students about learning and curiosity.


Leonardo da Vinci is famous for painting the Mona Lisa, sketching flying machines centuries before airplanes, and imagining tanks and helicopters.
But what many people don't know is that embedded in those thousands of notebook pages—hidden between anatomical sketches and architectural blueprints—are detailed chemical notes and early chemistry experiments. Leonardo wasn't a trained chemist. The term "chemistry" itself hadn't been properly defined in his time (the 1400s–1500s). Yet his approach to understanding how things work—by mixing, testing, observing, and recording—was pure chemistry.
This blog is written from Chemonboard's perspective, where we believe that Leonardo's way of learning has something profound to teach modern students, especially those in Classes 11 and 12 who think chemistry is just memorizing formulae.
Who was Leonardo, and why did he care about "chemistry"?
Leonardo da Vinci (1452–1519) lived during the Italian Renaissance, a time when the world was shifting from medieval thinking to modern science.
He wasn't just an artist. He was an engineer, anatomist, botanist, physicist, inventor, and naturalist all rolled into one. His notebooks—now preserved in libraries across Europe—contain over 7,000 pages of observations, sketches, and notes on seemingly every topic imaginable.

What fascinates Chemonboard most is Leonardo's insatiable curiosity about materials and transformations.
He studied:
How paint pigments mix and fade over time
How metals corrode and can be strengthened
How water moves, dissolves, and erodes
How clay transforms when fired in a kiln
How smoke, fire, and air interact
How dyes and inks bond to different surfaces

Leonardo didn't call these "chemistry", but that's exactly what they were. He was observing reactions, testing combinations, and understanding how substances change.
Leonardo's chemistry: Curious, messy, and brilliant
One fascinating example is Leonardo's obsession with paint and preservation. He wanted to understand why some paints lasted centuries while others faded or cracked.
In his notebooks, he recorded hundreds of observations:
How different oils (linseed, walnut, poppy) affected paint texture
What happened when you heated pigments to different temperatures
How humidity affected the drying process
Why certain colour combinations created optical illusions
He mixed, tested, and refined—exactly like a modern chemistry experiment. He didn't have the periodic table or chemical equations, but he had the scientific method: observe, hypothesize, test, record, refine.

What's striking is that Leonardo didn't just do this for art. He was genuinely interested in understanding the principles. He wanted to know the why behind every transformation.
Leonardo's approach: The opposite of rote learning
Here's what makes Leonardo's way of learning so relevant for students today, especially those struggling with chemistry:
1. He connected everything to real life.
Leonardo didn't study chemistry in isolation. He studied it because he was building something, painting something, or trying to solve a real problem. His motivation was always practical—"How can I make this work better?"

Modern students often feel chemistry is irrelevant. But like Leonardo, if you ask "Why does this matter to me?"—whether it's understanding medicines, materials, food, or even art—everything becomes connected and interesting.
2. He was unapologetically hands-on.
Leonardo's notebooks aren't clean and organized like a textbook. They're messy. Sketches overlap with notes. Observations are scattered. Experiments seem random.
Yet this "mess" is where real learning happens. He didn't memorize facts; he observed and questioned.

At Chemonboard, we encourage the same approach: rather than memorizing that "copper reacts with oxygen to form copper oxide," we ask, "Why does a copper coin turn green over time? What's actually happening at the molecular level?"
3. He recorded everything obsessively.
Leonardo didn't just do one experiment and move on. He repeated tests, noted variations, and looked for patterns.
If a particular paint mixture didn't work, he would try again with slight changes—temperature, oil type, pigment amount—and record what happened. Sound familiar? That's the scientific method.
For chemistry students, this translates to: don't just solve a numerical problem once and forget it. Try variations. Ask what happens if you change a variable. Record your thinking.
4. He was comfortable with uncertainty.
Many of Leonardo's notes end with questions, not answers. "Why does this happen?" "What if I try this instead?" "I don't understand yet."
This is the opposite of the fear many students have: the need to know the right answer immediately.
Leonardo's approach was comfortable with not knowing—as long as he was curious and willing to keep exploring. That mindset transforms chemistry from a terrifying subject into a fascinating puzzle.
What Chemistry looked like in Leonardo's time
When Leonardo was alive, "chemistry" (or alchemy, as it was called) was mixing various substances hoping to find gold, create immortality potions, or understand the nature of matter.
It wasn't organized. It had no periodic table, no understanding of atoms and molecules, no systematic naming of compounds.
Yet Leonardo brought to it the same precision, curiosity, and observation that defines modern chemistry. He was documenting behaviour, patterns, and cause-and-effect without the modern language to describe them.
Why this matters for Classes 11 and 12 students
Chemonboard works with students who say things like: "Chemistry feels like random facts I have to memorize," or "I don't understand how all these reactions connect," or "I don't see how this matters in real life."
Leonardo's approach is an antidote to this.
He shows us that:
Curiosity matters more than prior knowledge. Leonardo had no formal chemistry training, but his questions were brilliant.
Understanding beats memorization. He wanted to know why things happened, not just that they happened.
Real-world problems drive learning. All of Leonardo's chemistry came from trying to solve practical problems—making better paints, understanding materials, improving techniques.
Repetition and refinement are how mastery happens. He didn't expect to understand something instantly; he tested, refined, and improved over time.
In Classes 11 and 12 chemistry, you're expected to understand atomic structure, bonding, equilibrium, and organic mechanisms. It feels abstract and disconnected.
But if you approach it like Leonardo—asking questions, connecting to real-world examples (medicines, batteries, materials, food), testing your understanding through problems, and being okay with not knowing everything immediately—the subject transforms.

Chemistry as Renaissance thinking
The Renaissance was called a "rebirth" of classical knowledge, but it was really about a new way of thinking: empirical, questioning, curious, and hands-on.
Leonardo embodied this. He looked at the world and asked, "How does this work? What if I change this? Why does this happen?"
That's chemistry. That's science. And it's exactly how Chemonboard teaches: not as a list of facts to memorize, but as a language for understanding the world.
The broader lesson: Chemistry is everywhere, and curiosity is your superpower
One reason many students think chemistry doesn't relate to them is that they've never been asked to notice chemistry happening around them.
But like Leonardo, once you start looking, chemistry is everywhere:
In the browning of bread when it bakes (Maillard reaction)
In how your phone battery works (electrochemistry)
In why some fabrics are waterproof and others aren't (material chemistry)
In how medicines target specific cells in your body (biochemistry)
In the colours in fireworks (metal ions and light)
In how plants convert sunlight to energy (photosynthesis)
Leonardo didn't have chemistry textbooks, but he had his eyes, his hands, and his relentless curiosity.
You have all of that, plus access to organized knowledge, past papers, expert guidance, and tools like Chemonboard.
The question is: are you willing to be curious?
Ready to learn chemistry like Leonardo?
If you're in Class 11 or 12 and chemistry currently feels like a burden rather than a fascinating puzzle, it's time to change your approach.
At Chemonboard, we teach chemistry the way Leonardo would have—by making you curious about how things work, connecting every concept to the real world, and building your confidence one step at a time.
You don't need to be a genius or a "chemistry person." You just need curiosity and the right guidance.

On the surface, this sounds practical, especially if you dream of becoming a software engineer, designer, economist, or entrepreneur. But once students see where chemistry quietly sits behind their food, medicines, gadgets, and even career options, their relationship with the subject changes completely. 
This blog is written from Chemonboard’s experience of teaching diverse students across CBSE, ICSE, IGCSE, and IB boards in Classes 11 and 12, many of whom started by “hating” chemistry and ended by saying, “I wish I had seen it like this earlier.” 
Chemistry is hiding in your everyday life .
Before thinking of chemistry as a tough textbook, think of it as the science of “what everything is made of” and “how it changes”. Every single day, you are performing little chemistry experiments without calling them experiments. 
- Milk turning sour in summer is chemistry. 
- Iron railing rusting on your balcony is chemistry. 
- Pressure cooker whistles, rising cakes, burning LPG, your favourite perfume, the foam in your shampoo – all are chemistry in action. 
The food on your plate is made of carbohydrates, proteins, fats, vitamins, and minerals, each with its own structure and reactions in the body. 
The medicine you take for a fever is a carefully designed molecule that must be effective and safe, and that is pure chemistry plus biology working together. 
Once students begin connecting classroom topics like acids and bases, redox reactions, or organic chemistry to real products in their home, the subject stops being a list of chapters and becomes a way of seeing the world more clearly. 
 Chemistry trains powerful thinking skills 
At Chemonboard, chemistry is not just “one more subject” to score marks in; it is a training ground for your mind. 
When you balance a chemical equation, trace a reaction mechanism, or solve a numerical problem, you are using the same skills that strong problem solvers use in any field. 
Chemistry helps you develop: 
- Logical reasoning: You learn to ask, “If this bond breaks, what forms next?” or “If concentration changes, how will equilibrium shift?” 
- Pattern recognition: Seeing trends in the periodic table, understanding why certain structures are more stable, or predicting properties from bonding patterns. 
- Multi‑step problem solving: Using multiple concepts together – like mole concept, stoichiometry, and limiting reagent – to reach the final answer.
These are the exact skills valued in engineering, coding, research, finance, and management later in life. So even if you never work in a laboratory, the mental muscle you build through chemistry stays with you. 
In Chemonboard sessions, students are not just given formulae; they are guided to think step by step until they themselves can explain “why” a concept works, not just “what” to memorize. 
 How chemistry connects to different careers 
Chemistry is obviously central if you want to become a doctor, pharmacist, scientist, or chemical engineer. 
But its reach goes much further than that. 
- Medicine and healthcare: Drug design, medical diagnostics, vaccines, anesthesia, medical devices – all rely on strong chemistry at the core. 
- Engineering: Materials for buildings, aircraft, cars, electronics, batteries, and solar panels are designed using principles of physical and inorganic chemistry. 
- Environment and sustainability: Water purification, air quality control, waste management, and green energy all require people who understand chemical processes deeply. 
- Everyday industries: Cosmetics, paints, textiles, food processing, packaging, agriculture, and cleaning products all employ chemists and chemical engineers. 
New‑age careers are also becoming highly chemistry‑driven. 
Data scientists now work with chemists to speed up drug discovery, and people interested in design work with material scientists to create better fabrics, devices, and sustainable products. 
A simple way to think about it is: 
- If you like biology and helping people, chemistry is your bridge to medicine, pharmacy, biotechnology, and research. 
- If you enjoy physics and maths, chemistry connects you to materials science, nanotechnology, energy, and many branches of engineering. 
- If you love design and creativity, chemistry opens doors into cosmetics, fragrances, food science, and sustainable product design. 

By taking chemistry seriously in Classes 11 and 12, you keep many doors open instead of quietly closing them just because the subject “felt hard” in the beginning. 
 Chemistry and your school exams 
For most students Chemonboard works with, the near‑term pressure is doing well in school tests and board exams. [chemonboard](https://www.chemonboard.net)
Chemistry carries significant weightage in CBSE, ICSE, IGCSE, and IB, and often becomes the deciding factor between an “average” and a “stand‑out” result. The problem is that many students treat chemistry as a subject to be memorized in the last few weeks. 
They try to mug up reactions, named reactions, mechanisms, and formulae without building a clear picture of concepts like bonding, equilibrium, thermodynamics, or organic families. 

Chemonboard’s approach is different: 
- Build strong conceptual foundations early, so revision is about connecting and practising, not panicking. 
- Use past paper patterns and carefully selected questions so students understand what examiners are really testing. 
- Help each student develop a strategy for attempting the paper – which sections to tackle first, how to manage time, and how to avoid typical mistakes. 
Once students feel that chemistry “makes sense”, their confidence goes up, and that reflects in both their school and board exam scores. 
  Common myths students have about chemistry 
Over the years of mentoring, Chemonboard sees the same three myths repeated again and again. [chemonboard](https://www.chemonboard.net)
1. “Chemistry is just memory.” 
 When you see chemistry as isolated facts, it feels like memory work. 
 But when you see how atomic structure leads to bonding, which leads to properties, which leads to reactions, a lot of “memory burden” disappears because there is a logical story. 
2. “Either you are a ‘chemistry person,’ or you are not.” 
Many students decide very early that they are “bad at chemistry” because of one bad test or a few confusing classes. 
In reality, most students have gaps in their basics and need someone to rebuild the foundation with them patiently. 
3. “Online chemistry can’t be effective.” 
 Students and parents sometimes worry that online classes mean less attention. 
But Chemonboard’s 1‑to‑1 style, use of digital whiteboard, structured notes, and focused doubt‑clearing actually give many students more clarity than crowded offline coaching. [chemonboard](https://www.chemonboard.net)
Once these myths are dispelled, students begin to approach the subject with a calmer, more open mind. 
 How Chemonboard makes chemistry click 
Chemonboard was created as a dedicated online chemistry space for school students who want more than just “finishing the syllabus”. [chemonboard](https://www.chemonboard.net)
The focus is on clarity, confidence, and real understanding – the three pillars that change how a student feels about the subject. 
In a typical Chemonboard journey, students: 
- Get personal attention, with the freedom to ask basic questions without feeling judged. 
- See each topic connected to everyday life and to their future goals, not taught in isolation. 
- Practise questions chosen for their board and class level, with detailed discussion of mistakes and alternative methods. 

Chemonboard works with CBSE, ICSE, IGCSE, and IB students of Classes 11 and 12, but the heart of the approach is always the same: help you see that chemistry is not a monster to be feared but a language you can learn to speak fluently with the right guidance. 

 Ready to change your chemistry story? 
If chemistry currently feels heavy, confusing, or “just not your subject”, you are exactly the type of student Chemonboard is designed for. 
With the right explanations, pace, and support, many students who once dreaded chemistry have turned it into a scoring subject and discovered a new interest in science.

Class 12 chemistry has a reputation—and honestly, I get why. The syllabus is vast, concepts feel interconnected, and exams expect both understanding and accuracy. Over the years, I’ve worked with many students who felt overwhelmed at first but went on to perform really well with the right approach.

Here’s what I tell every Class 12 student who asks me: chemistry is not about memorising everything—it’s about understanding patterns and practising smartly.

Let’s break it down.


1. Get Your Basics Strong (This Is Non-Negotiable)

Most difficulties in Class 12 chemistry come from weak fundamentals in:

  • mole concept

  • chemical bonding

  • basic organic reactions

Before rushing into reactions or numericals, pause and ask yourself: Do I understand why this happens?
When concepts are clear, reactions stop feeling random and numericals stop feeling scary.

👉 Tip: If a chapter feels impossible, go one level back and revise the prerequisite concept.


2. Don’t Treat Organic Chemistry Like a Memory Game

Organic chemistry is where many students panic—but it’s actually very logical.

Instead of memorising reactions:

  • understand why a reagent works

  • focus on reaction mechanisms

  • group similar reactions together

Once you see the patterns, organic chemistry becomes predictable—and even enjoyable.

👉 Tip: Practice writing reactions neatly and step-by-step. Presentation matters in board exams.


3. Practice Numericals the Right Way

In physical chemistry, students often “understand” concepts but lose marks due to:

  • wrong formulas

  • unit mistakes

  • rushed calculations

The only fix? Consistent practice.

👉 Tip:

  • Write formulas before substituting values

  • Always include units

  • Practice previous years’ board questions regularly

Accuracy improves only with repetition.


4. NCERT Is Your Best Friend

This may sound obvious, but it’s extremely important.

For Class 12 boards:

  • NCERT lines are often asked directly

  • diagrams, tables, and examples matter

  • even small paragraphs can turn into 2–3 mark questions

👉 Tip: Read NCERT actively—underline, annotate, and revise it multiple times.


5. Revise Smart, Not Just Hard

Revision isn’t about reading everything again the night before.

Effective revision includes:

  • short notes for reactions and formulas

  • regular mock tests

  • analysing mistakes (this part is crucial!)

👉 Tip: Make an “error notebook” where you write mistakes you repeat. This alone can boost marks significantly.


Final Words

You don’t need to be a “chemistry genius” to do well in Class 12. What you need is:

  • clear concepts

  • consistent practice

  • guidance that matches your learning style

If chemistry feels overwhelming right now, that doesn’t mean you’re bad at it—it just means you haven’t found the right approach yet.

Take it one chapter at a time. Progress adds up faster than you think.
