EXPERIMENT 3 OBSERVING BROWNIAN MOTION AT A MICROSCOPIC SCALE RACHAEL THEISEN CHESTER GAUSS BRENDA KIZY INTRODUCTION • Brownian Motion • Random movement of particles in fluid that can be observed microscopically • They move randomly because the fluid that surrounds them collides with the adjacent particles in random movements INTRODUCTION •In experiments that observe Brownian Motion, particles are surrounded by a fluid (liquid or gas) that bounce off of the particles and make their movement random and quick due to many collisions EXPERIMENT • Goal: To analyze random motion of objects (beads) in fluid • 1. Test how the mass of beads will impact their motion • 2. Test how the size of beads will impact their motion • 3. Test how the viscosity of a fluid will impact the randomized motion of beads EXPERIMENT • 1. Test how the mass of beads will impact their motion • Using three different mass beads EXPERIMENT • 2. Test how the size of beads will impact their motion • Using three b
