Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

1. Arm - Supports the body tube and is used for carrying the microscope. 2. Diaphragm - Controls the amount of light passing through the opening of the stage and into the microscope. 3. Stage - Supports the slide being used. You place the slide on it. 4. Mirror or Light - Reflects or shines light upward through the diaphragm to illuminate the specimen. 5. Nosepiece - Holds the different objective lenses; allows the lenses to rotate for viewing. 6. Base - Supports

that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid can apply force normal to any surface contacting it. If the fluid is considered as a solid object such as a cylinder‚ the pressure acting on a surface is the same as the pressure on the opposite side

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

Introduction: The purpose of this lab is to see how the colour of an apple would change (browning) over time‚ when placed in different conditions. When referring to the term “browning”‚ it is meant to imply the change of colour that occurs inside the apple‚ giving an appearance that is distasteful (Di Guardo et al.‚ 2013). Specifically‚ within this lab the apple was cut into 4 pieces with 3 pieces being placed on a weigh boat‚ and a 4th piece placed in a beaker of water. These weigh boats were

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential
