NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

Contrast the way that two texts you have studied are constructed to appeal to particular audiences. Both plays and films‚ although different genres‚ can be effective in bring an issue into focus by appealing to particular audiences. No Sugar‚ written by Jack Davis in 1985 is a social realist play that depicts the isolation and disempowerment of Aborigines during the 1930’s. Various dramatic conventions have been employed to highlight the negative effect of the Eurocentric‚ hypocritical and dominant

the percent centralizations of starch in two distinct arrangements. It showed us through the strategy utilized‚ which was osmosis (the dispersion of watered). Osmosis normally indicates on the grounds that it began to change in the mass for both the dialysis tubing loaded with the bizarre arrangement and the container of sucrose and water. Demonstrated that dissemination of water had happened over the semi-penetrable dialysis tubing. It’s checked on the grounds that the weight both changed. The outcomes

2 What drove the sugar trade? “Give me some sugar!” When most people hear that phrase‚ it usually means someone wants a kiss. But in the late 1600s and early 1700s‚ people want to plant sugar. True‚ it started some 9000 years ago in New Guinea‚ but it took a while before the rest of the world caught on. During this time‚ there was a movement called the sugar trade. Although there were many forces driving the sugar trade‚ what mainly drove it were the ideal land masses for sugar production‚ the amount

Many things helped drive the sugar trade. Demand‚ slavery‚ and climate played a major role in the driving of the sugar trade. Demand was greatly increasing throughout the years. The climate of the caribbean islands where cane sugar was grown. Slavery provided “free” work to produce sugar which in turn increased profits for the farmers. In England‚ sugar was not shipped there until the year 1317. But once the sugar was becoming a popular import‚ it boomed. Sugar consumption and import grew tremendously

! Experimental Method: Does a large amount of sugar affect attention in small children?! Independent Variable: Amount of sugar given to children! Dependent Variable: Children’s attention! ! In a class of 20 kids (average age of 7)‚ 5 kids get 25 grams of sugar‚ 5 kids get 35 grams of sugar‚ 5 kids get 45 grams of sugar‚ and 5 kids don’t get any (the control).! 20 minutes after consumption‚ all of the children take a long yet simple math test. Record who is still paying attention to the test after

The Sugar Revolution Revolution means a complete change in a system. There was an economic revolution that occurred in the 17th Century. Some refer to it as the Sugar Revolution. During this period‚ several basic changes took place. (1) Sugar replaced tobacco as the chief export crop in the Caribbean. (2) The population changed from one that was mainly white to one that was mainly black because of the introduction of African slaves. (3) The size of land holdings changed. This change was pioneered

materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in the cell is
