- Graph 1.0 shows a gradual increase in skin temperature of the hot test subject (Sara Withers) throughout the duration of the 20 minutes with a peak of 33.6 °C at 18 minutes, a 3.7 °C increase from the skin temperature reading at the commencement of the experiment, 29.9 °C. The graph also shows a substantial gradual decrease in skin temperature of the cold test subject (Kirsty Hatton) throughout the duration of the 20 minutes with an all-time low of 20.8 at 6 minutes, a decrease of 9.7 °C from the skin temperature reading at the commencement of the experiment, 30.5 °C, and a low of 22.9 at 20 minutes, a decrease of 7.6 °C from the skin temperature reading at the commencement of the experiment, 30.5 °C. Overall, graph 1.0 shows an increasing trend in the skin temperature of the hot subject (Sara Withers) – skin temperature increases with the passing of time and a decreasing trend in the skin temperature of the cold subject (Kirsty Hatton) – skin temperature decreases with the passing of time. - Graph 1.1 shows a gradual and very minor increase in core temperature of the hot test subject (Sara Withers) throughout the duration of the 20 minutes with a peak of 35.9 °C at 8 minutes, 12 minutes and 20 minutes a 0.6 °C increase from the core temperature reading at the commencement of the experiment, 35.3 °C and a 0.7 °C increase from the core temperature reading taken at 4 minutes, 35.2 °C. The graph also shows a gradual increase in core temperature of the cold test subject (Kirsty Hatton) throughout the duration of the 20 minutes with a peak of 36.8 °C at 20 minutes, a 1.7 °C increase from the core temperature reading at the commencement of the experiment, 35.1°C. Graph 1.1 shows a very mild increasing trend in the core temperature of both the hot subject (Sara Withers) and the cold subject (Kirsty Hatton) – core temperature increases with the passing of time, however the gradient of this trending line, as shown, is very gentle, demonstrating the body’s ability to maintain a relatively constant internal environment within narrow limits despite fluctuations in the external environment. - Graph 1.2 shows a fairly constant trend in the core temperature of the hot subject (Sara Withers) with all temperatures falling between 35.9°C and 35.2°C throughout the 20 minutes demonstrating that the core temperature of this test subject remained almost constant despite the much hotter external environmental temperature. …show more content…
This trend shown contrasts with the trend of that of the skin temperature of the hot subject (Sara Withers) also shown on the graph. The trend shown by the graph for the skin temperature of the hot subject (Sara Withers) is an increasing trend – the skin temperature increases with the passing of time. Graph 1.2 shows a gradual increase in skin temperature of the hot test subject (Sara Withers) throughout the duration of the 20 minutes with a peak of 33.6 °C at 18 minutes, a 3.7 °C increase from the skin temperature reading at the commencement of the experiment, 29.9 °C. - Graph 1.3 shows a fairly constant, slightly increasing trend in the core temperature of the cold subject (Kirsty Hatton) - core temperature increases with the passing of time, however the gradient of this trending line, as shown, is very gentle. A gradual increase in core temperature of the cold test subject (Kirsty Hatton) throughout the duration of the 20 minutes is shown with a peak of 36.8 °C at 20 minutes, a 1.7 °C increase from the core temperature reading at the commencement of the experiment, 35.1°C with all temperatures falling between 35.1°C and 36.8°C throughout the 20 minutes demonstrating that the core temperature of this test subject remained almost constant despite the much colder external environmental temperature.
