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.

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding

(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 weighed on

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

The Great Antacid Culminating Lab Purpose: To determine which antacid tablet is the most effective. Materials: 3 different antacid tablets‚ thymol blue‚ droppers‚ pH probe and necessary cables‚ pH probe holder‚ retort stand‚ 1 mol/L HCl‚ droppers‚ five 150 mL beaker‚ mortar and pestle‚ graduated cylinder‚ balance‚ weighing dish‚ stir rod Procedure: 1) Gather all the equipment you will need to do the lab. You will be working in groups of 3 2) Calibrate the pH probe as you practiced the day

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

Module 6 Reporting and Analyzing Operating Assets DISCUSSION QUESTIONS Q6-1. When a company increases its allowance for uncollectible accounts‚ it also records bad debt expense in the income statement. If a company overestimates the allowance account‚ bad debt expense is too high and net income is understated. As well‚ accounts receivable (net of the allowance account) and total assets are both understated on the balance sheet. In future periods‚ the company will not need to add as much
