Introduction: In this experiment I aim to investigate the effect of the surface area to volume ratio on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent:

increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled variable: - Equal size of potatoes used - Using measuring cylinder Equipment used: - Gas collecting kit - Potato - Stop watch - Test tube - Distilled water - Hydrogen

Aim: This experiment aims to determine what effect an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears
