Hello 2021, hello Chemistry

New year, new me, new chemistry

Chemistry in upper secondary offers a fresh start to your chemistry with science.

Proton: Getting particular about identifying elements

The proton is the subatomic particle that defines the chemical identity of an element.

Electron: What we know and can never know

The electron is the first subatomic particle to be discovered, turning chemistry on its head more than a century ago.

Kinetic particle theory

The kinetic particle theory explains the visible with the invisible.

Cher, I forgot everything

What is atomic structure?

The atom is not a featureless ball. It consists subatomic particles arranged in a mind-boggling way.

Our commitment to access

We are a group of young science teachers based in Singapore.

We believe in freebies access. Educational resources should be accessible to all, both financially and conceptually. So we are committed to keeping everything on the website free. Let there be no paywall, subscription fee, or DLC. We also use plain language and memes analogies familiar to the young in Singapore.

We believe in diversity. We respect that every child has a unique learning style. That’s why we have multiple authors to write about Chemistry from different angles, with different voices. We hope you can find articles that speak to you, that enrich your learning.

Surely, our notes will help you overcome the O Level Chemistry exams. But life is more than that, and Chemistry too. We will show you the exciting aspect of Chemistry through our stories on everyday applications, folk knowledge, history of science, philosophy, and the latest scientific breakthrough.
