11 national parks in England & Wales, containing over 1800 miles of footpaths through some of Britain's most beautiful countryside. I am sure that we were going to cover at least over half of the area. The area around Grasmere, Ambleside, and Coniston & Windermere forms the hub of the tourist activity during the summer months and are perfect places to base walking and camping trips which we were about to find out. We were gloomy and quickly began to comprehend the next three days were only
The Football Field The wheels on the bus went round and round, all the way to Paonia. The ten mile trip seemed to last forever. Whoosh, Whoosh was the only sound could be heard as the wheels ran through the new rain puddles that were created earlier that day. It was dead silent, you could have heard a pin drop. We all knew what was at stake. For each of us it was a different thing, but on both sides of the ball we knew that in order to have bragging rights for the rest of our lives this would
urbanised drainage basins of Tokyo. A drainage basin is an area of the land's surface from which a river receives its supply of water. An imaginary line can mark the edge of a drainage basin. This is called the watershed. The other main features of a drainage basin are shown in figure 1. The drainage basin relies on the atmosphere for its inputs of water, whilst water passes through the drainage basin leaves the system either to return to the atmosphere or to become an input into the coastal
how salt solution concentration affect the mass of potatoes, I will investigate how much the mass of a potato changes if I leave it in a beaker of water with a specified salt concentration for half an hour. I will change the salt concentration after each experiment. Background Knowledge -------------------- Osmosis is the passage of water molecules from a weaker solution to a stronger solution through a partially permeable membrane. A partially permeable membrane only allows small molecules
in my actual experiment. My experiment consisted of using three off 2 cm's of potato chip and three off 3 cm's of potato chip. I only placed them in three solutions which were concentrated sugar solution; dilute sugar solution and distilled water. I left them for 24 hours thean recorded the results. The results that I obtained were percentage increase or decrease in the length of the potato. I used the following instruments to collect my results: Cork Borer (size 5), Measuring cylinder
catchment, which has led to a threefold increase in its built-up areas; the concrete and tarmac send more water to the river than the fields which they replaced. Also pressure for use as farmland or building means that the Rhine has lost much of its riverside marsh and floodplain that used to hold back floodwater. [IMAGE] Results: - ---------- Floods can cause great damage to land and water-related constructions, which can have disastrous consequences for people and economies, both short
Environmental Pollution Our environment is affected by our daily actions. The earth is plagued with land, air and water pollution. Some of the problems we face on earth are: deforestation, nuclear waste, acid rain, global warming, overpopulation and some animals are endangered. Air pollution has many different sources. Power-generated plants, oil refineries, chemical plants, and steel mills contribute to about 140 million tons of pollutants into the air every year. Automobiles account
solution on potato chips. Hypothesis: I would expect the potato chips to turn flaccid when they are placed in a strong sucrose solution because the water from within the cells will diffuse out leaving the potato flaccid. The potato chips left in the weak sucrose solutions should turn turgid in a weak sucrose solution, due to the water being absorbed by osmosis into the cells of the potatoes, this will make the potato chip larger in size. I should also be able to find some potato chips
Determining the Water Potential of Potato Tuber Cells I will carry out an investigation that will enable me to determine the water potential of the tested potato tuber cells. Water Potential is the measurement of the tendency of water molecules to move from one place to another. (Ridge 1991) Water always moves down the water potential gradient, therefore moving from an area of higher water potential to an area of lower water potential. Equilibrium is reached when the water potential in
the land with tarmac in urban areas humans have increased the rate of surface runoff and decreased the saturation levels of the ground. When surface runoff is high rainwater reaches the river faster. It would appear that the speed in which the water reached the river was too fast for the river to handle. The river filled up reaching bank-full discharge and then overflowing its banks onto the flood plain. The flood plain of the River Severn is built on, therefore, when the river floods it floods
The Movement of Water and Solutes in Plants During the process of osmosis, water molecules move from an area that is hypotonic to an area that is hypertonic. A hypotonic area is one in which has less solute and a hypertonic area is one which has more solute. Plant cells, such as the ones in the epidermis and cortex regions of the roots of the plant, all have living contents, which are enclosed by a cell surface membrane and a thick, quite inelastic cellulose cell wall. The cell wall
trail to where it stops at the creek's edge, approaching quietly so as not to disturb any of the wild creatures that has come to enjoy the cool fresh water. I gently cross over the creek using the stones, which show the wear of several previous crossing, so that I can have full view of the creek and the beauty it possesses. I can hear the rush of the water long before I see the falls. As I sit down on the big gray slate rock that has been warmed by the early morning sun, I begin to gulp in the beauty
concentration of sucrose in it; and therefore a low region of water. I think this because I think that more water will come out of the cell than into the cell. The distilled water will add to the to the weight of the potato cylinder because there is more water in it so that osmosis can easily occur. Here I think more water will come into the cell than out of the cell. Equipment: Potatoes Cork Borers Distilled Water 1M Sugar Solution Beakers Measuring Cylinders Rulers
Background Knowledge: Osmosis is a special type of diffusion involving the movement of water molecules through a partially permeable membrane and is defined as the movement of water or any other solution from a high concentration to a low one through a semi permeable membrane e.g. cell wall. This could be a cell wall that will allow small molecules to pass through it but not large ones. For example if pure water and a strong sugar solution are separated by a membrane then osmosis will occur.
Experiment Growth of a Beans Experiment Aim: To compare the growth of bean seedlings in a different soil solution. Background Knowledge: Plants make there own food by photosynthesis. They need light and CO2 from the atmosphere and the water absorbed from the soil. Plants also need very small quantities of minerals for healthy growth. Mineral ions are absorbed through the roots from the dissolved chemicals compounds in the soil. When garden centres sell bottles of “Plant Food” they
concentration of particles on one side of the cell membrane than on the other. This will lead to the water particles diffusing from an area of higher concentration to an area of lower concentration. [IMAGE]The diagram to the right shows a partially permeable membrane. There is a higher concentration of water on the left side of the membrane. This means that the diffusion will cause the water particles to move from the left side to right side of the membrane. Variables: The variable that
Rate of Reaction with Sodium Thiosulphate Solution Aim I aim to investigate how changing the concentration of Hydrochloric acid affects the rate of reaction with Sodium Thiosulphate solution. [IMAGE]Sodium + Hydrochloric Sodium + Water + Sulphur + Sulphur Thiosulphate Acid Chloride Dioxide (aq) (aq) (aq) (l) (g) (s) The reaction makes the solution go a yellow cloudy colour and a gas is given off
information thus. Osmosis:- Osmosis is basically a form of diffusion, but more specifically: it is the movement of water molecules from an area of high water concentration, through a partially permeable membrane to an area of lower water concentration. Partially permeable membrane:- A partially permeable membrane is a membrane, with holes so small that only water molecules are small enough to fit through, bigger molecule, for instance, sugar and salt are not small enough to fit through

Using a set of scales I weighed out 14.625 grams of sodium chloride on a piece of filter paper 2. I then transferred the sodium chloride in to a 250ml beaker. 3. I then rinse the filter paper with distilled water to make sure that all the sodium chloride was
osmosis. The scientific theory of osmosis is the diffusion of water through a selectively permeable membrane into a more concentrated solution of sucrose. Because the more concentrated solution contains a lower concentration of water molecules, the water flows by diffusion to dilute it until concentrations of solvent are equal on both sides of the membrane. In simple terms, it may also be thought of as the passage of water molecules from a low solution to a high one, across a selectively
