Lab Jessica Cimaroli Lab 1 Purpose To learn about the International System of Units (SI) system and how it relates to measurements in mass, length, temperature, volume, and time. To learn about the common techniques and laboratory equipment used to make SI measurents. Procedure Length Measurements 1. Gather the metric ruler, CD or DVD, key, spoon, and fork. 2. Look at the calibration marks on your ruler to determine the degree of uncertainty and number of significant figures that can be made when measuring with a ruler. 3. Measure the length of each of the following objects with the ruler in (cm), to one degree of uncertainty and record of Data Table 1. 4. Measure the length of each object with the ruler in millimeters (mm), to one degree of uncertainty, and record in Data Table 1. 5. Convert the measurements for each of the objects from millimeters to meters and record in Data Table 1. Temperature Measurements 6. Gather materials determine the degree of uncertainty and number of significant figures that can be made when measuring temperature. 7. Look at the calibration marks on the thermometer and determine the degree of uncertainty and number of significant figures that can be made when measuring temperature. 8. Turn on the tap water to hot. Let the water run for approximately 15 seconds. 9. Fill the 100-mL glass beaker with approximately 75 mL of hot tap water. 10. Measure the temperature of the hot tap water in Celsius to one degree of uncertainty. Record the measurement in Data Table 2. 11. Place the beaker of water on the wire gauze burner stand.

I first started off by getting two objects to measure the desk, lab table, and the door with. The objects I used were a meter long dowel and a meter stick with markings on it. Next off I created a data table in my lab notebook to record the measurements I got when I measure the height, width, and length of the door, lab table, and the desk. Once that was finished I measured the desk’s height, width, and length with the dowel and recorded the measurements in my data table. Then I used the meter stick with markings to measure the desk’s height, width, and length and recorded those measurements in my data table. Next I used the dowel to measure the lab table’s length, width and height, height, width, and length and recorded those measurements…

The numerical value of a laboratory measurement should always be recorded with the proper number of significant figures. The number of significant figures depends on the instrument or measuring device used and is equal to the digits definitely known from the scale divisions marked on the instrument plus one estimated or “doubtful” digit. The last, estimated, digit represents the uncertainty in the measurement and indicates the precision of the instrument.…
