1. Title: Laboratory Techniques and Measurements
2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length, temperatures, volume, density, and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula.
3. Procedure: In order to perform this lab I needed the following materials: a metric ruler, table salt, small number of ice cubes, piece of string, flame source, rubbing alcohol, tap water, distilled water, paper, colored liquid drink, 100mL glass beaker, burner-fuel, burner-stand, 25 mL cylinder, 25mL volumetric …show more content…
7. Results: The results for this lab are detailed in my observation charts. I measured different objects lengths, temperatures, volumes, mass, and densities. I measure three different lengths in centimeters and millimeters. I measured the temperatures of hot water, boiling water, cold water, and iced water. I found the results of both of these extremely accurate. I measured the volume of a test tube, the number of drops in 1mL, and the volume of a pipet. I also found the density of water, rubbing alcohol, salt and a couple of irregular objects including a bolt and a magnet. When finding the density of the irregular objects I followed numerous methods, including the water displacement method, Archimedes’ method, and math calculation method. I was very careful throughout the lab in order to be accurate. My husband double checked my work and took photos of me doing the experiment.
8. Conclusions: This experiment was concerning the
