Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

The purpose of this experiment was to determine the effects of temperature on the elasticity of rubber bands. There were three hypotheses: If the 0.157 cm rubber bands are heated to about 100˚C in water for one minute‚ then the rubber bands will stretch to approximately 60 cm; If the 0.157 cm rubber bands are cooled to 0˚C in water for one minute‚ then the rubber bands will stretch to approximately 40 cm; If the 0.157 cm rubber bands are left in room temperature water for one minute

Candide Voltaire‚ a French philosophe and writer‚ wrote this document during the Enlightenment. He illustrates his opinion on many Enlightenment ideas‚ such as Leibnizian optimism‚ deism‚ and religious tolerance. He impacted many people‚ including Benjamin Franklin and Thomas Jefferson with his belief of religious toleration and civil rights. His view on organized religion also influenced the French Revolution. One of the Enlightenment views Voltaire addresses is Leibnizian optimism‚ or the

DIFFUSION AND OSMOSIS Chapter 3 of your textbook explains diffusion and osmosis. Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration. The force behind the movement is heat or kinetic energy (also called Brownian motion). Diffusion occurs when you spill water on the carpet floor and it spreads out‚ or when you open a bottle of perfume and it leaves the bottle and spreads throughout the air in the room. Osmosis is a

Biology GCSE Coursework: Osmosis in Potato Chips Skill Area P: Planning Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Hypothesis: Osmosis is defined as the net movement of water or any other solution’s molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially

Osmosis Osmosis is just a special case of diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at
