Activity 3.2 — Malleability & Ductility
NCERT Activity 3.2: Hammer metal pieces on an anvil to observe malleability, then draw them through a plate to observe ductility.
How To Perform
1
Hammer Iron
Place an iron piece on the anvil and strike it with a hammer. It flattens into a thin sheet (malleability).
2
Draw Iron into Wire
Pull the iron sheet through a draw plate. It becomes a thin wire (ductility).
3
Hammer Aluminium
Repeat with aluminium — observe how it flattens even more easily. Gold is the most malleable metal!
4
Draw Aluminium into Wire
Draw aluminium into a wire. Aluminium is used in overhead power lines for this reason.
5
Check Your Understanding
Answer a question about why metals can be drawn into wires but non-metals cannot.
⚠️ Safety Notes
- •Wear safety goggles while hammering — small metal fragments can fly off.
- •Hold small pieces with tongs, not bare fingers.
