of three separated components Research Question: Is it possible to separate salt‚ sand and iron filings from each other in a mixture‚ to figure out the percentage of each component in the original mixture? Background Research: In this Investigation‚ I will be separating sand‚ salt‚ iron fillings in a mixture and finding their percentages. Iron is a magnetic solid which is incapable of being dissolved in water. Salt is a non-magnetic solid which is capable of being dissolved in water. Sand is

the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

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:

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water

Title: Food Energy Lab Report Date of Activity: 8-28-13 through 8-29-13 Purpose: The purpose of the lab was to measure the amount of energy contained in a gram of certain foods. Hypothesis/Prediction: I hypothesize that some of the foods are going to be difficult to burn. Procedure: 1. Weigh the weight of empty can and food items. 2. Fill can approximately one third full of water. 3. Weigh the can after water is in the can. 4. Take the temperature of the water in the can. 5. Place the

Title: Creating the chemical reaction of Osmosis with an Egg. Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Introduction: When trying to create an osmosis reaction‚ it is important to understand

Case Study : Morton Salt 1. Briefly describe salt production‚ from brine production to finished round cans. Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns‚ allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid‚ resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce
