It is important to become familiar with various laboratory techniques. This lab will help  us gain proficiency with some of the more common measuring devices used in  chemistry. A common knowledge of unit measurements most frequently used in  laboratory experiments will be gained during my experiment (Noteworthy information is  that scientific measurements are carried out using metric units.). Additionally, I will  become accustomed to using different methods to calculate Volume, Density, Mass,  and Temperature. (i.e. Archimedes principle and water-displacement method). I will take  note that often times measured results will differ from theoretical expectations and there  will be variations within repeated measurements. Procedure: I began the experiment by acquiring all necessary materials that I needed to provide  (metric ruler, table salt, ice, string, ad rubbing alcohol), and then sifting through my  ChemKit to find the provided materials. I will begin by measuring the lengths of three  objects. I will then take warm water measurements by filling my beaker up with 100ml of  water, and then boiling for 5 minutes. Next, I will take cold water measurements using  the same method, using the beaker with the exception of using cold tap water. By using  the graduated cylinder and checking the meniscus I will take accurate volume readings.  After reading the instructions on how to properly use my digital scale I will take mass  measurements of various items and chemicals. Finally, I will use data collected to  calculate density measurements of certain items provided in my auxiliary lab bag. After
