Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

The History of the Potato Chip One of the most recognizable snack foods is the potato chip. Who can resist this thin slice of potato‚ fried into a crisp then salted? Potato chips are delicious and very popular. They satisfy the taste buds of many by hitting all the essential characteristics of a good treat. They are convenient‚ easily found‚ salty‚ greasy‚ and come in a wide variety of flavors. It is hard to believe their invention was a mistake. When George Crum‚ a Native American chef in Saratoga

Global Variations in the Potato Crisps and Potato Chips Market It’s fair to assume that consumer snacking habits are likely to differ from country to country‚ particularly across different regions and cultures. A clear example is the consumption of potato crisps / potato chips which can be seen in the bar chart below. 86% of consumers throughout the USA and France consume potato crisps / potato chips closely followed by 84% of GB consumers. On the other end of the scale is the Chinese market

BIOLOGY OSMOSIS LAB REPORT 1. Research Question/ Aim How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be

Data Collection: The aim of this experiment was to test the weight of six potatoes before and after being put into different sucrose solutions. The following data was observed and collected throughout the experiment. Observations: -Qualitative: The potatoes were: Tubed shaped Yellow in color Initially hard in texture -Quantitative: Table 1: Weight of the potato in grams before and after placed in a different concentrations of sucrose solutions. Sucrose solution (M) Weight Before (g) ±

Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

Chapter 1 By: Ciara Rafferty “You see I think everything’s terrible anyhow‚” she went on in a convinced way. “Everybody thinks so—the most advanced people. And I know. I’vebeen everywhere and seen everything and done everything.” Her eyes flashed around her in a defiant way‚ rather like Tom’s‚ and she laughed with thrilling scorn. “Sophisticated—God I’m sophisticated!” (21). This passage perfectly depicts the unhappiness that Daisy experiences from day to day. The life that she had

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Thus‚ diffusion should not be confused with convection or advection‚ which are other transport mechanisms that use bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach starting

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic
