01.07 Accuracy and Precision: Balance Lab Worksheet
Measurement * Measurement is an important skill used for data collection and data analysis. Careful attention to the accuracy and degree of uncertainty of each measuring device is necessary for proper data collection. Significant figures are used to record or report measurements accurately. * This laboratory activity will give you the opportunity to get more familiar with some of the basic measuring devices that are common in chemistry labs. You will use the measurements performed in this lab to calculate density.
Procedure * Access the virtual lab and complete the experiments.
Data * Below is the table that you will complete for the virtual lab. Either type your results into this table or print the table from the virtual lab (it must be submitted to receive full credit for this assignment.) * To print from the virtual lab. 1. Be sure the data table is viewable. 2. Right-click (PC) or Command-Click (Mac) on the table and select print.
