An Experiment to Investigate the Effects of the Centroid Bias on the Judgment of the Inclination and Separation
An Experiment to Investigate the Effects of the Centroid Bias on the Judgment of the Inclination and Separation. Abstract The aim of this investigation was to observe how a red dot in a cluster of blue dots would affect the way one perceived the inclination and separation of lines between the two red dots. The research hypothesis was the varying distance would affect the error judgment. The design used to test this hypothesis was experimentation.

Osmosis and Potatoes
Osmosis is a specialised form of diffusion. Water moves from an area of LOW concentration of Solute to an area of HIGH concentration of solute through a semi-or fully permeable membrane by the process. Water moves constantly through the cell’s membrane its estimated that about 250 times the volume of a single cell moves through 1 per second This continues until the solute concentration reaches equilibrium It is convenient to express the available energy per

Investigating the Effect of Intraspecific Competition on the Growth of Mung Beans
Investigating the effect of intraspecific competition on the growth of mung beans Introduction When plants reproduce, size is highly correlated with reproductive. The struggle for reproductive survival among plants is the struggle to grow in the face of competition from neighbours. So the question this experiment asks is how competition affects the growth of plants. A plant growing in a nutrient-abundant environment free from competition will exhibit maximum growth. One way to address this question

Osmosis in Potatoes
Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month, but if they didn't have water to drink they will be dead within a week. Hoping to postpone the inevitable, their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor

Osmosis in Potato Chips
The biological importance of water and its role in living organisms What is water? Water (from the Old English word water) is a colourless, tasteless, and odourless substance that is essential to all known forms of life and is known also as the most universal solvent. Water has a very simple atomic structure, the structure consist of two hydrogen atoms bonded to an oxygen atom, which can also be related to as hydrogen oxide.

Investigating Osmosis
Osmosis is the diffusion of water molecules across a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration, to an area of low concentration. So, Osmosis is the movement of water molecules from an area where there are lots of water molecules to an area where there are few water molecules. Our aim is to find the concentration of dissolved substances in the cells of a potato using Osmosis. I

Osmosis with Potato Chips
My Investigation on osmosis Osmosis is a special kind of diffusion. While diffusion can describe the movement of any kind of molecule, osmosis is only about the movement of water molecules. To show this diffusion I will be using potato discs, of the same size and mass, in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar

Osmosis Investigation
Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane, with

The Effect of Ph on the Rate of Osmosis Using a Glucose Solution
The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang, osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang, 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic

The Effects of Concentration on Osmosis
Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece, 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent, the other

An Experiment into the Effect of Sugar Concentration on Osmosis
An experiment into the effect of sugar concentration on osmosis Background information Osmosis is the movement of water molecules from a dilute solution to a concentrated solution through a partially permeable membrane. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other.
