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 …show more content…

Tare the scale by pressing the Φ/T button so that the scale reads 0.0 g. 17. Place the magnet on the scale to measure the mass of the object. Record the mass in Data Table 6. 18. Fill the graduated cylinder with 6 - 8 mL of distilled water. Record the volume in Data Table 6. 19. Place the magnet into the graduated cylinder and read the volume of the graduated cylinder. Record the volume in Data Table 6, next to “Final volume of graduated cylinder.” 20. Determine the volume of the object, by calculating the difference in water displacement volumes (final – initial). Record in Data Table 6. 21. Calculate the density of the magnet and record in Data Table 6. 22. Carefully pour the water from the cylinder down the drain and collect the magnet. 23. Repeat steps 16 through 22 for the metal bolt. archimedes’ method 24. Tare the scale by pressing the Φ/T button so that the scale reads 0.0 g. 25. Place the metal bolt on the scale to measure the mass of the object. Record the mass in Data Table 7. 26. Attach the end of the string to the metal bolt by tying the string to the bolt. 27. Fill the glass beaker approximately 3⁄4 full with distilled water and place the beaker on the scale. 28. Tare the scale by pressing the Φ/T button so that the scale reads 0.0 g. Refer to Figure 11 as
