One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

Sample Short Lab Report By Charles M Borener Jr April 24‚ 2009 Kinetic Friction Experiment #13 Joe Solution E00123456 Partner - Jane Answers PHY 221 Lab Instructor – Chuck Borener Thursday‚ 11 AM – 1 PM Lecture Instructor – Dr. Jacobs Abstract In this experiment‚ we test factors which effect friction. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

molecules and water are very vital processes for many living organisms. There is active and passive transport; active transport includes functions of a cell membrane to selectively push specific types of molecules across the membrane and there is passive transport in which it does not have need of an active role for the membrane. Osmosis and dialysis are also occasionally called passive transports because they too do not require an active role for the membrane. Osmosis is movement of water across a semipermeable

Finding the best quality paper towel Question: Which paper towel has the highest quality overall? Background: Past tests of the highest quality paper towel showed that Bounty was the best choice for a kitchen paper towel. Although it wasn’t the most absorbent‚ which was Brawny‚ it was rather strong in both durability and absorbency.

changesthe coefficient of kinetic friction between them. Finally‚ in both parts‚ we showed that friction depends on the normal force. OBJECTIVES 1. To determine the coefficient of friction μ between contact surfaces as one body moves uniform motion. 2. To establish the relationship between angle of repose ∅ and μ METHODOLOGY Determination of the coefficient of Friction. - Place the wooden plane horizontally. Measure the weight of the block. Slowly add weights in the pan until you observe

November 20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4 of the candy
