Beads, Beads (Sharhea and Shanika)

Submitted by Sharhea on Thu, 10/04/2007 - 2:35pm.

At the beginning of class, we discussed how molecules may be dispersed throughout water. We tried different temperatures and observed how the blue dye dispersed throughout the water. With our observation, we assumed that due to the temperature of the water the blue may disperse more slowly and/or faster. In cold water, the blue dye dispersed slower than when it was in hot water or room temperature.

Movement: Sometimes the beads are vibrating or moving swiftly. Our data may be skewed due to the vibrations at one point and the swift movements at another time of observations. Observations for each Bead:

 

2microns - beads 2 microns-beads 4microns- beads 4microns -beads 8microns beads
Time 1min 2min 1min 2min 1min
Distance 12*2.6 =31.1micrometer 40*2.6 =104 micrometer 40*2.6 =104 micrometer 28*2.6 =72.8 micrometer No movement
Magnification 40x 40x 40x 40x 40x
