The first lab started with us viewing sea urchin fertilization and cleavage. To do this, we prepared a culture chamber with three different concentrations of sea water, 1/2x, 1x, and 2x. We were able to see the actual process of fertilization with the various concentrations or sea water. Next, we were to prepare chick embryos of different ages (33, 72, 96 hours). We prepared the embryos using the filter paper technique under sterile conditions, which uses a ringed filter paper to isolate the chick embryo. This was the end of the first portion
