Kristen Sierman Lab Report: Experiment #7 Group #4 October 16th‚ 2012 Forces on a Pulley System A. Statement of the Problem The purpose of this lab was to address the following questions: how does the acceleration of a pulley system depend on the mass of the driving objects? And how does the acceleration of a pulley system depend on the mass of the driven object? To achieve this‚ a dynamic track was set up with a string attached to a cart. The string was part of a pulley system (the pulley

The Osmosis Lab SHS Lacrosse Monster #2 Dates performed: 10/10/11 and 10/11/11 Introduction: The purpose of the laboratory investigation was to observe the diffusion of water across a semi-permeable membrane. In this lab‚ dialysis tubing was used to represent the semi-permeable cell membrane. Three dialysis tubes were prepared with 5% sucrose solution and were soaked in solutions of different concentrations. The diffusion of water across a semi-permeable membrane is called osmosis. When
