Lesson 0 of 10
Start here
Show on a big screenA drop of ink falls into a bucket of water. Soon the whole bucket looks blue.
Nobody stirred it. How did one drop reach every corner?
This is Chapter 7, Particulate Nature of Matter. One picture of tiny pieces explains it.
What you will learn
- Pieces too small to see — what a substance is made of.
- Gaps between them — where dissolved sugar goes.
- They never stop moving — why a colour or a smell spreads.
- Three arrangements — solid, liquid and gas.
- Warming them up — melting point and boiling point.
- Squeezing — why air squeezes and water does not.
- Using the picture — answer real questions with it.
Need a quick recap?
- Solid, liquid, or gas? (Track Zero) — most things take one form.
- Same water, three forms (A Journey through States of Water) — one substance.
- Dissolving is not disappearing (same track) — sugar breaks into tiny pieces.
- Melting and boiling (Changes Around Us) — heat changes a thing's state.
Stay safe
Nothing here is real. Every glass and bowl is on the screen. Do not taste anything you meet in a lab.
