Introduction
Along with solids, liquids also act as conductors
Pre-Requisites:
Conductors of electricity
Activity:
Construct a circuit to see if liquids conduct electricity . Use normal water, salt water, lemon juice.
Real Life Question:
Many people have died due to open wires falling in water pools. How is that possible?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Conductors | Materials that transmits electricity |
