 +
===Meaning===
 +
The law of '''Conservation of Strangeness''' is the observation that during the [[Strong Nuclear Interaction|strong nuclear interaction]] the sum of the [[Hadron]]s' [[strangeness]] is the same before and after that interaction.
 +
 +
===About Conservation of Strangeness===
 +
: [[Strange-quark]]s have a [[strangeness]] of -1.
 +
: [[Strange-quark|Anti-strange-quark]]s have a [[strangeness]] of +1.
 +
: If a [[Strange-quark]] comes into existence an [[Strange-quark|Anti-strange-quark]] must also come into existence.
 +
: '''Conservation of Strangeness''' cannot be applied to the [[Weak Nuclear Interaction|weak nuclear interaction]].

Key Stage 5

Meaning

The law of Conservation of Strangeness is the observation that during the strong nuclear interaction the sum of the Hadrons' strangeness is the same before and after that interaction.

About Conservation of Strangeness

Strange-quarks have a strangeness of -1.
Anti-strange-quarks have a strangeness of +1.
If a Strange-quark comes into existence an Anti-strange-quark must also come into existence.
Conservation of Strangeness cannot be applied to the weak nuclear interaction.
