Legend & what you're seeing
Air Molecules - Fast-moving particles
Pollen Grain - Larger particle exhibiting random motion
💡 What you're seeing: Hundreds of air molecules bombard the pollen grain
from all directions. The unbalanced collisions cause the pollen to move randomly -
this is Brownian motion, first observed by Robert Brown in 1827!
🌡️ Temperature Effect: Higher temperature means faster-moving air molecules, which causes more energetic Brownian motion. This demonstrates the direct relationship between temperature and molecular kinetic energy!

Displacement vs Time
Graph explanation
📊 Graph Explanation: This graph shows how far the pollen grain has moved
from its starting position over time. The jagged, irregular pattern is characteristic of
Brownian motion - there's no smooth predictable path!
