Ruth & Samar's Report

Submitted by Ruth Goodlaxson on Wed, 10/03/2007 - 1:41pm.

From the discussion, we hypothesized that the smaller microspheres would have a larger diameter of motion relative to their size than the larger micropheres, because the motion of the molecules would have greater effect on them.

Unfortunately, due to our difficulties with the microscpoe, we were only able to gather data for 2 micron beads. We measured the jitter of two beads, and found that their movement had a diameter of 26 and 20.8 microns. We didn't feel we could really draw conclusions from this data becacuse we have no point of comparison. However, it does support that water molecules are randomly moving.
