identify a metal‚ each with varying amounts of accuracy. In order to test some of these methods‚ thermal expansion‚ density‚ and specific heat were used to identify two small metal rods. The overall purpose of this experiment was to identify an unknown metal using the three previously stated properties. This means that the percent error should be relatively low‚ meaning that there would be little difference between the values measured in our experiment and the true values of the metal. Density

They would make us clean our rooms or do our homework‚ but if we did not‚ they tell us that the "boogieman" would come find us at night.

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus
