    A summary of Diffusion of Innovations Les Robinson Fully revised and rewritten Jan 2009 Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea‚ behaviour‚ or object that is perceived as new by its audience. Diffusion of Innovations offers three valuable insights into the process of social change: - What qualities make an innovation spread successfully. - The importance of peer-peer conversations and peer networks.

    DATE: 21.08.2013 TITLE: Transport across membrane OBJECTIVES: To investigate the effect of concentration of blackcurrant squash on osmosis in chipped potatoes. INTRODUCTION: In biology‚ osmosis is defined as the diffusion of solvent molecules (usually water molecules) across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Osmosis is of great importance in biological processes

    DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

    1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

    Effects of Osmosis and Diffusion The experimentation of last week’s lab was in order to test the many effects of diffusion and osmosis amongst four experiments. One such experiment was testing the effects of molecular weight on diffusion in relation to the use of Agar. The methods performed included the use of two acids‚ HCl and acetic acid. Both acids were placed into an Agar-filled dish and‚ over increments of 15 minutes‚ data collection was taken based off the diffusion rate and the diameter

    Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements of
