Sub Topic Name : Particles Of Matter Are Continuously Moving |
|
Introduction
Discuss “Why can’t we see them moving”
Pre-Requisites:
Matter is made up of particles, Particles have space between them
Activity:
When we start boiling water observe what happens.
Real Life Question:
“What is the reason behind these particles to keep on moving?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| kinetic energy | Energy that a body possesses by virtue of being in motion. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| A beaker, water and copper sulphate crystals | Drop a crystal of copper sulphate or potassium permanganate into a glass of hot water and another containing cold water. Now observe and note down observations. |
Real life uses :
Now we know how to increase kinetic energy of particles
Practical examples around us
| Examples | Explainations |
|---|---|
| All states of matter | The particles are continuously in motion |
| When you heat anything it changes it’s state | The kinetic energy starts increasing. |
What you learn in Theory:
Matter particles are continuously moving
What you learn in Practice:
All particles possess kinetic energy
