Sensors And Instrumentation

Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.

Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

In order to maintain a healthy body temperature, the heat produced with in the body or absorbed from the environment must be balanced from the heat lost from the body. A normal body temperature is measured at 37 degrees.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

Calibration tells you if the instrument is accurate or not. Based on that knowledge, you can adjust it to get a more accurate reading.

The results of this lab helped determine which tools are best to measure different objects. In Station 1, a yellow metric ruler, an orange metric ruler, a wooden ruler, and a measuring tape was used. The tool with the highest degree certainty was the orange metric ruler. This is because the orange ruler had tick marks for each 10th(0.1). The tool with the lowest degree of certainty was the measuring tape because it kept moving and it was difficult to keep it straight. For Station 2, a wall clock, a digital stopwatch, and a timer was used. The tool that had the most accurate measurement was the digital stopwatch because it measured into the 10th(0.1) place automatically. The tool that was least accurate was the wall clock because

Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the

Specific measure instruments are used in quantitative research. Gathered measurements are recorded on a chart, which can reveal how small changes between individual measurements may equal to a more noticeable change over a period of time.

\paragraph{\textbf{Instrument-based Analysis}} Instrument-based methods measure the body movements using specific instruments (e.g., accelerometers and motion sensors) attached to the infant’s skin.

Now that I have discussed pros and cons of each method, I will now explain the instrument that I will be using as an example. I will be using stock options as the instrument. Stock options are offered by many businesses to employees that stay with the company for a specified length of time. It is offered by the company as an

In 2000, the National Council of Teachers of Mathematics provided a definition of ‘Measurement’ as being a process by which a number is assigned to an attribute of an object or event (McDonald, 2013).
