(2 pts each = 6 pts) EXP 1: Physical Measurements and Error Analysis Grading WebAssign prelab: 5 pts This template: 30 pts Lab Notebook Duplicate: 5 pts By signing below, you certify that you have not falsified data and that you have not plagiarized any part of this lab report. Failure to sign this declaration will cost you 5 points. Signature: Purpose and Method Things to think about: What is the goal of this experiment? Explain how it is accomplished. What is the general method (not step by step detailed procedure) that you will be using to achieve this goal? How will you process the data that you record in lab? (What calculations will you use and how do you obtain all of the values to plug into those equations?) (5 points) The goal of this experiment is to determine whether or not our measurements /readings are accurate during the experiments performed throughout this laboratory exercise. We will be measuring the amount of water in vials using a graduated cylinder as well as mass and volume readings, then measuring density. Then, we will be using a buret and measuring the amount of water using mass and volume readings on the
