Regulation of “home schooling” Abstract Three major investigations were conducted in an effort to determine the impact of home school regulations on educational enrollments in the United States. Home school regulations were obtained from state departments of education and investigated to determine the strength of the accountability

Cell Size: Is Bigger Better? Problem: Why are cells small? Objective: To see the relationship between cell size and diffusion of materials. Hypothesis: If we cut three different sizes of cells‚ then the smallest one will survive the longest due to its sufficient permeable membrane.

1.0 Introduction 1.1 Aim and Assumptions: The aim of this experiment is to observe the rate of diffusion of diethyl ether vapour into stagnant air‚ and then determine the diffusivity. An error analysis of this calculation also had to be carried out. The following assumptions made were: * Diethyl Ether is an ideal gas * Partial pressure at the top of the tube was equal to zero * Mass transfer resistance between the liquid surface at the bottom of the tube is insufficient‚ compared with the

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no

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

Case Studies Abstract Alfredo Cano Abstract Innovative methods in language teaching may sometimes be slightly difficult for less experienced teachers. Case studies are a relatively new type of task-based activities for business English students. They have been used in language courses for some time now. It seems‚ however‚ that their full teaching potential has not been used yet. Teachers seem to be uncertain of how to use cases in class.The paper presents the main pedagogical aspects of

Practical 7 Osmosis Name: Diana Baktybayeva Tutorial Group: D Lab Partner: Nurlan Mukazhanov Day: Monday afternoon Date: 17.11.14 Title: Osmosis Introduction. Osmosis is a particular type of passive transport involving the movement of water molecules from the region of low solute concentration to the region of high solute concentration through semi permeable membrane‚ which allows movement of solvent molecules‚ but not solute. The main principle of osmosis is to equalize

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:
