Density Lab Partners: Betty Alcaraz Date: 9/10/13 Teacher: Wright Class: 7th period Introduction/Purpose: To determine the densities of unknown substances. Pre-Lab: 1. Which is heavier‚ a pound of feathers or a pound of lead? a. A pound of lead. 2. What is the density of a mineral if 427 g of the mineral occupy a volume of 35.0cm3? b. 12.2g/cm3 3. The water level in a graduated cylinder stands at 20.0 mL before and at 26.2 mL after a 16.74 g metal sample

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1.

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

Business Continuity Planning Lab #6. A risk assessment is a process to identify potential hazards and analyze what could happen if a hazard occurs. A business impact analysis (BIA) is the process for determining the potential impacts resulting from the interruption of time sensitive or critical business processes. A business continuity plan is a roadmap for continuing operations under adverse conditions such as a storm or a crime. A disaster recovery plan‚ is a plan for business continuity

Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible
