2 micron beads:

5 trials, 1 minute trials, at the x40 objective

1^st Trial: 4 units=10.4

2^nd Trial: 19 units – messed up possibly because of microscope movement=49.4

3^rd Trial: 3 units=7.8

4^th Trial: 4 units =10.4

5^th Trial: 4 units=10.4

Average: 6.8=17.68

w/o trial 2: 3.75=9.75

4 micron beads:

1^st Trial: 5 units=13

2^nd Trial: 2 units=5.2

3^rd Trial: 1 unit=2.6

4^th Trial: 1 unit=2.6

5^th Trial: 1.5 units=3.9

Observations:

The beads were moving much faster when we first set up the slide because they hadn’t settled. The smaller ones had a lot greater movement than the larger ones.
