Petri Dish Lab

In this lab experiment, we compared the amount of germinated Raphanus sativus’ in normal and frigid temperatures. My group and I predicted that more seeds in the normal temperature atmosphere would germinate, rather than the seeds in the frigid condition. The experiment starts with two petri dishes, and we filled each dish with fifty radish seeds. We made our first observations about the seeds that we see. We labeled one petri dish “Control,” and the other was labeled “Experimental.” The experimental petri dish was put in the freezer for seven days, and the control petri dish was set on the counter in the normal-temp classroom for seven days as well. After those seven days, the experimental dish was removed from the freezer, and we used a graduated
