on the movement of microbeads.

Observations
2-micron microbeads: 26.8 microns

4-micron microbeads: 43.3 microns

8-micron microbeads: 5.63 microns

*We started out with the hypothesis that temperature and size affect the movement/speed of molecule. The bigger the molecule, the slower the movement; the smaller the molecule, the faster the movement.

Although our data is inconsistent with our hypothesis in terms of size affecting speed, we think that the 4-micron microbead could have had an offset piece of data because only one of the three trials, the 4-micron microbead moved farther than the 2-micron microbead.
