Demo first, mole concept second
The single ordering change that fixed my Grade 11 results — and why most textbooks run the reaction backwards.
Read note →14 years teaching Chemistry to Grades 9–12. My students burn, bubble, precipitate and titrate before they memorise a single equation — because a reaction you've smelled is a reaction you never forget.
I fell for chemistry at eleven, when a teacher dropped potassium permanganate into glycerine and the bench caught fire in the most educational way possible. I finished a Ph.D. in organic synthesis, spent two years at a pharma bench, and then admitted what I'd known since that fire: I wanted to be the person holding the demonstration.
Fourteen years on, my lab runs like a kitchen and reads like a courtroom — everything gets tested, everything gets logged. My students have standardised their own solutions since Grade 9, run a soap-and-ester micro-business for the school fete, and walked out with 278 NEET and JEE qualifications. The board average sits at 95%; the safety record sits at perfect.
If your school wants a chemistry department where the lab is used weekly instead of photographed for the brochure — where children argue about mechanisms at lunch — mix me in. I bring my own flame-test kit.
Fourteen years of chemistry, physical to organic — all analytical grade.
Chemistry has a reputation problem: children meet it as a wall of equations before they ever see anything change colour. I run it in the right order. First the flash, the smell, the precipitate — then the mole concept arrives as the grammar of something they've already witnessed. Lower the activation energy and every student reacts.
Lead a five-teacher department. Moved practicals from twice-a-term to weekly, built the salt-analysis olympiad that four schools now join, and run the NEET/JEE chemistry stream — 278 qualifiers with a 95% board average alongside.
Grades 11–12 chemistry; started the ester micro-business (soaps and scents for the school fete) that quietly teaches stoichiometry, costing and honesty about yields.
Two years of process chemistry; discovered that explaining a mechanism was more satisfying than running it. Left with a Ph.D., excellent glassware discipline, and a demonstration habit.

Read note →NEET chemistry rewards students who autopsy their mistakes. A simple notebook system that compounds.
Read note →Esters, sulphides and the pedagogical value of a room that smells like actual chemistry happened in it.
Read note →My daughter now explains why onions make you cry, at length, with diagrams, to guests. Dr. Venkat has created a monster and we love her.
Meenakshi's fatherPARENT · GR 12Weekly practicals sounded like a logistics nightmare. She made it run like clockwork, and our science admissions enquiries doubled.
PrincipalCHETTINAD VIDYASHRAMI got through NEET organic because she taught mechanisms like gossip — who attacks whom, and why. I'm in med school. It still works.
