Animal Behavior Lab
In this lab activity, my lab group experimented how roly polies would react to changes in their environment. the first step was to gather a few roly polies and a sample of their natural habitat. Then we would bring the specimens back to the lab tables and place then into two connected petri dish chambers. The variable we were testing was how temperature affects the behavior of the roly polies, so for our experiment, one of the petri dishes was set at a 100 degrees Celsius while the other petri dish was left at room temperature. The main goal of the lab was to observe and record the roly polies' behaviors in different environments. After completing this lab, I learned that if animals were isolated from their natural environment, they would tend to find an area that most resembles their natural habitat to reside in.

DNA Electrophroresis Lab
In this lab, my lab group mixed DNA with different digestive enzymes. The purpose of this lab was to able to identify the role of restriction enzymes in genetic manipulation because these enzymes "cut" DNA at specific regions, which allows the DNA to combined with other matching segments. In the beginning, each lab member started with the same amount of the same DNA sample. Then we would add different enzymes to the DNA, centrifuge the solution, and then pipette the solution into the well of the gel. After that, the an electric current will pass through the gel, forcing the spliced DNA segments down the gel. Finally, once the current had run for a certain amount of time, my lab group would be able to analyze the resulting gel and determine the different lengths at which the DNA had been cut. From this lab, I have learned about the value of restriction enzymes in genetic engineering and about the different biological uses for gel eletrophoresis.
