Created page with "==Key Stage 3== ===Meaning=== Brownian Motion is the seemingly random movement of very small, visible, particles when viewed under a microscope. ===About Brownian..."

New page

==Key Stage 3==
===Meaning===
[[Brownian Motion]] is the seemingly random movement of very small, visible, [[particle]]s when viewed under a [[microscope]].

===About Brownian Motion===
: Brownian Motion is [[evidence]] of the [[Particle Model|particle model]] of [[matter]].
: When viewed under a [[microscope]] small [[object]s like a [[pollen]] grain or tea leaf seem to change direction randomly.
: [[Brownian Motion]] can be [[explain]]ed if the small [[object]]s are being hit by other, even smaller [[object]]s that cannot be seen. This is [[evidence]] that [[matter]] is made of [[particle]]s.
