Abstract:
In this laboratory we utilize simple measures of physical quantities (for example, distance, and mass) and use the measurements to calculate or convert other physical quantities (such volume and area). We also use mathematical calculations and formulas to make conversions from one unit of measurement into another unit of measurement (for example, a conversion from meters to centimeters or Fahrenheit to Celsius)

Introduction:
Biology is a science based on observation--if a physical concept or theory is to be considered a valid one, it must agree with what is observed to actually occur in the real world. In order for this to happen, scientists utilize the scientific method in which to support hypotheses, which later become theories.

Because biology is a science based on observation, quantitative observations and measurements are central to the data that is collected and analyzed during scientific. Without knowing how to make good measurements and convert them into other measurements, we cannot observe the scientific world. Thus, we cannot test and support hypotheses made based on observations made. The measurement process is used all areas of science including biology, chemistry and physics. Measurements are also used in other areas of everyday life, from agriculture to medicine to manufacturing, where observations, experimentations, and scientific discoveries are important.

As important as a measurement is there a knowledge of the uncertainty associated with the. (For instance, when using instrument such as scales and thermometers, there is always a margin of error.) In our lab work it is important to keep such uncertainties in mind and use conversions to measure such measurement against other units of measurement measurements to insure the most accurate data during laboratory experiments. The utilization

    To predict caloric expenditure you can plug in a measured heart rate and calculate the predicted VO2 (L/min). Then using the predicted VO2 and an estimated thermal equivalent (4.825 kcal/LO2), you can estimate the caloric expenditure. Nonetheless, each individual’s heart rate varies. These can be attributed to gender differences, physical activity and physical training. So, if the person is of the same gender and is as healthy as you are and does the same amount of exercise then it could be possible to use their regression line to estimate your own caloric expenditure however the limitations would be possibly the difference in size of the lungs for the estimation of VO2 max. Weight would be important, as it is required to calculate the predicted caloric expenditure. However if your weight can be misleading because one can simply weigh more because they are taller, not because they are bigger. Height does not play such an important role. When you are taller, your body does need to pump more blood throughout the body. This means that they will pump more blood per beat but not that they would have a higher heart rate. It is important to remember that a linear relationship exists between…

    A scientist would initially observe and classify data. He would proceed to look for pattern in the data and formulate a hypothesis. Following this, the scientist would make a predication. The scientist would test this predictions through experiments. If the experimental results confirm the hypothesis, a scientific law has been discovered. The scientific method limits the influence of bias and prejudice in the experimenter. It provides an objective, standardized approach to conducting an experiment and, in doing…
