Senior Writing Seminar 13 December 2012 The Irish Potato Famine Six long years‚ with over 1 million dead‚ and nearly a quarter of the population missing‚ the Irish Potato Famine left a massive imprint in history (Irish 1). Most people underestimate the destruction of the Potato Famine because 1 million does not look like very many in today’s population numbers. Back in the 1800’s‚ less than 8 million populated Ireland.

Investigation into finding out the Effect of the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2)

IDENTIFICATION AND CLASSIFICATION OF PARAMETERS THAT MEASURE FITNESS OF EACH PRODUCT I. INTRODUCTION Potato is a cool-season vegetable that ranks with wheat and rice as one of the most important staple crops in the human diet around the world. The white potato is referred to as the "Irish potato" because it is associated with the potato famine in Ireland in the 19th century. Potatoes are not roots but specialized underground storage stems called "tubers." Maximal tuber formation occurs at soil

of osmosis of tap water of Solanum tuberosum L. Solanum tuberosum L.‚ also known as potato‚ was the selected plant to be tested because it was easy to measure the percentage change in mass due to the osmosis of water into the tissue. RESEARCH QUESTION How does the surface area to volume ratio of potato tissue (Solanum tuberosum L.) affect the rate of osmosis of tap water? HYPOTHESIS The smallest cube of potato (1x1x1)‚ having a higher surface area to volume ratio‚ will have the fastest rate of

of Osmosis” The purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups. About 24 hours later‚ the potatoes were taken out

Project: Agricultural Science Name: Ciara Murphy Farm: Rathconrath Co. Westmeath Livestock: Breed of Cow: On my farm the farmer bred British Friesian Cattle. Friesian cattle are a breed of cattle known today as the world’s highest production dairy animal. Originating in Europe Friesian’s were bred it what is now called the Netherlands. The farmer chose British Friesian over any other breed as he finds they are a more dual-purpose cow. This means the cow produces good milk and also has

he uses some local expressions “My grandfather could cut... than any other man on Toner’s bog”‚ he uses that expression because of a local bog business owned by a family‚ whose name was Toner. The setting of this poem brings the reader at to a potato farm‚ and at a bog’s field as the writer Seamus Heaney writes about his father and his grandfather’s working lives‚ “My father digging... by God‚ the old man could handle a spade‚ just like his old man.” The Poet started his poem with the present

small molecules to pass through - the larger the organism‚ the smaller the surface area ratio.Therefore if ratio is too small it take molecules much more longer to enter cell. Prediction For the experiment‚ I expect to see different effects on potato samples depending on different water concentration: · After putting in dilute solution I expect their mass to increase‚ as effect of taking up water by osmosis - cell should become ‘turgid’. · Concentrated glucose solution - mass of potatoes samples

The Science of the Spud — a History of the Potato Battery Experiment There are hot potatoes‚ french fried potatoes‚ baked potatoes and scalloped potatoes. There are potato chips‚ potato pies and potato soufflés. Last‚ but not least‚ there’s the potato battery. Who on earth invented the electric spud? Why does it work? For that matter‚ why would anyone want to see if a potato could conduct electricity in the first place? Well‚ we may never be able to answer some of the questions this quirky experiment
