Osmosis Aim: To determine the concentration of cell sap in a potato cell. Osmosis is the movement of water through a semi-permeable membrane. It starts from a weak solution and becomes a more stronger solution until the concentrations on both sides are equal. To investigate the range of solutions needed to find the point at which the surrounding solution is the same as the cell sap in the vacuole.

Specific Purpose: To educate my audience on sugar and its effects on the body. Central Idea: Many sugars have detrimental effects on our body and it is important that we pay closer attention to avoiding these foods. Intro: I. Did you know that the average American consumes around 130 pounds of sugar per year? I’m going to assume that you are surprised by this fact‚ as you should be‚ because this is way above the amounts that we should be consuming. II. Sugar is all around us in many different forms

The Effect of Health problems caused by Sugar Sophie Tacheci The Effect of Health problems caused by the amount of Sugar on the Drosophila Sugar intake has increased drastically since the 1820’s‚ causing over 78 ailments such as raised insulin levels‚ rising rates of obesity‚ heart disease and diabetes. Sugar intake per person during the 1820’s was about five pounds per year. Today the average sugar intake is about one hundred pounds per year‚ or about 119 grams

1890s. While experimenting around‚ Will made an unsweetened taste of cereal that sold 113‚400 pounds in1896. In doing that‚ he kept the experimenting ongoing with flakes of corn which later would be called the Sanitas Toasted Corn Flakes. Then the sugar was added secretly in. John was furious so Will set out on his own creating what we know today at Kellogg’s Toasted Corn Flakes. Churning out 2‚900 cases a day; the brothers became rivals and enemies‚ taking on another to court twice. After it all

Long and Short Term Effects of Refined Sugar Refined sugar is made from sucrose extracted from raw sugar cane or sugar beets. Often added to processed foods and beverages‚ refined sugar has several forms such as granulated white sugar‚ brown sugar‚ fructose‚ sucrose‚ dextrose‚ high fructose corn syrup and malt syrup. The average American consumes about 22 tsp. of refined sugars each day according to the American Heart Association (Marina). Refined sugars have led to an obesity epidemic in America

What is osmosis? Osmosis is the diffusion of water molecules through a semi permeable membrane. Why is it important? It is important to know what Osmosis is‚ and to understand it so that we understand what we are measuring‚ and so that we can use this understanding to apply to other situations so that we can gain further knowledge. We can also use this understanding to analyse our results. What we will do: We will put potato pieces of similar sizes in to test tubes of different concentrations

An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water through their roots‚ and is also used

SUGAR‚ SALT‚ FAT Our world‚ as a whole‚ is facing great challenges that affect our current and long-term health. We are stuck on the availability of processed food and need to break this vicious cycle that we are in. We need to take responsibility for ourselves and stop blaming it on consumerism. The big food companies have made it almost impossible to cut them out because health food is more expensive than what they offer. They have hooked us not only because of its

INTRODUCTION: Osmosis is defined as the net movement of water or any other solutions 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 permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium
