Pre-Requisites:
What are three states of matter
Activity:
Stand in front of a table fan and wave your hand, try stopping the flow with different objects and observe the properties
Real Life Question:
“What are the properties of gases we experience daily in our life? Give some examples”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Gaseous state of matter | the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Take few gases in balloon or in polybag | Understanding the properties of gases |
Real life uses :
Gases play a very important role in our daily lives. We take in oxygen, we use gases in refrigerators for cooling
Practical examples around us
| Examples | Explainations |
|---|---|
| All matter which do not have definite shape and can be easily compressed | They are all gaseous state of matter |
What you learn in Theory:
