Osmosis and the Egg Lab Report By: N. Mullins Date: January 20‚ 2011 Introduction This lab was designed to explain the different things osmosis does. Osmosis is the diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually

Projectile Motion PHYS111 Formal Report 2 University of Canterbury Campbell Moulder Abstract The force of gravity is said to be a constant of 9.81 ms-2 (3). This can be proved by measuring the projectile motion of a bouncy ball and plotting a ∆Vertical Velocity vs. Time graph‚ the gradient of which should equal the constant force (acceleration due to) of gravity. Our gradient value of 10.26±0.49 ms-2 is consistent with the actual value of 9.81 ms-2. Introduction A projectile is an

2. LINEAR MOTION In this experiment you will study the motion of an object in one dimension from a number of points of view. You will demonstrate how the variables of motion are related by differentiation and integration and investigate the relationship between potential and kinetic energy. Theory Why Study Motion? Motion is everywhere in the universe. Only at a temperature of absolute zero is the motion in any body truly absent. If motion exists then so also does energy. To the delight of

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

Lab 5: Osmosis Purpose: The purpose of this lab is to familiarize you with osmosis and‚ specifically‚ what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis: If we add higher concentrations of sugar to the dialysis tubing‚ then the net movement of coffee into the dialysis tubing will increase. Materials scale or balance 24" dialysis tubing 4 transfer pipets sugar scissors rubber bands four coffee cups - they need to be roughly the same size

Regents Physics Constant Velocity/ Acceleration Lab 10-3-13 Problem: Graphical Analysis of Constant Velocity and Accelerated Motion. Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate
