1. For this experiment, the independent variable is the type of mattress suture technique used – horizontal and vertical methods. The dependent variable is the amount of tension the stitches can withstand. This is determined by applying weights to increase the tension until the stitches give way. The constants (control variables) are the size and type of meat used, the number of stitches, the distance between the stitches and the type of fish hooks used. 2. Ten pieces of chicken breast are sliced to 10 mm thickness each. In this experiment, the side with the skin will be used ..... |
