Water Imagine, it is a hot summer’s day, you are walking down the street, the sun is burning your skin, you have been walking quite a while now and suddenly, you feel you are thirsty. So what would you do …. Probably you go to the nearest store down the street and buy a bottle of water; a bubbly water, a vitamin water, a water from the fridge, there is so many variety of waters and still you have something to complain about how the water is to expensive how the day is too hot, how the water is too cold . And now imagine… imagine the people, who live in African deserts, imagine feeling thirsty and not having any water at all, not around you, not anywhere. People who live there they have to make long journeys or treks over rough and barren land to get water and when they finally reach to that hole in the ground, then that water there isn’t even clean. It takes so much
Water pollution Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants and for all of us. First, we have to talk about the causes of water pollution. Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Dumping of litter in the sea can also cause huge problems. Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution. Virtually all types of water pollution are harmful to the health of humans and animals
Water Purification What is water purification? Water purification generally means freeing water from any kind of impurity it contains, such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some contaminants, such as oil, can be settled in a settling tank. They can then be removed easily, after they have reached the bottom of the tank. Removal of dangerous microorganisms Often polluted water has to be freed from microorganisms. The water is than disinfected, usually by means of chlorination. Removal of dissolved solids

Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos.
Water pollution and society This essay is about fresh water and pollution. It's based on an article by David Krantz and Brad Kifferstein. I read it through and now I'm trying to give the conclusion of the article as well as express my own opinion. 70 percent of planet Earth's surface contain water. Water is the beginning of life and vital natural resource. It's vital for every living organism. That's why we have to keep the water bodies clean and stop polluting our fresh water. It's hard to believe, but planet Earth is in great danger. People can't see the whole picture. They are being indifferent to the future. Everyone thinks about themselves and tries to find a better and easier way to get rid of garbage and waste. Money is everything for them. Money talks and nobody cares about giving a dollar to save the nature. Usually a person thinks that what difference can he make. But if everybody think so,
Does water consumption matter? 2 MINUTIT. I'm going to talk about water consumption and about the importance of the water. I've chosen this topic because water is our most important resource and I'm also very worried about how little there is left of it. At the moment a bottle of water costs less than an euro, but within the next 10 years the very same bottle may cost 5 to 10 euros, if we don't conserve and protect our fresh water supply. The thing is, we have enough sea water, but it's the freshwater we lack of. Water covers over 70% of the Earth, but just 3% of it is fresh and less than 1% is the water that is available and we can drink. The amount of freshwater is rapidly decreasing. The water we have now is all we will ever have, we cannot produce anymore. Moving on to the importance of water. There wouldn't be any life on Earth without water. Water cools the Earth and all plants, animals and humans need clean water to survive.
11b Dear Davy, Hi! How are you? I know that it been a while from my last letter. Soon is coming springbreake and I have lots of tests that I have to too before it.

How to save fresh water? We all know what the problem is. Our lakes are dirty, people are wasting water for no reason not understanding how important it is not to waste it because we may soon run out of fresh water. It can seem like there's no solution, but there is! A few simple changes can help a lot. First of all, it is really important to keep our lakes clean, because nature is the premier source of fresh water. So people should stop dropping garbage into the lakes or near them. And walking pets near the lakes is also not such a good idea. It's not very nice to find some animal's body wastes while going to swim. Secondly, think about how much water you use. A few simple steps could save your money and help protect the environment. For example you should prefer shower to bath or you should turn the water off while brushing your teeth.
How to Stop Water Pollution Water pollution is one of the biggest threats to the environment today. There are several sources of water pollution ranging from sewage and fertilizers to soil erosion. The impact of water pollution on wildlife and their natural habitat can be immense. While it may seem like preventing water pollution can be an overwhelming subject to tackle, there are also a number of things that the average person can do to help stop water pollution. Tips on Preventing Water Pollution The best solution for water pollution is prevention. While pollution that has already occurred is a current threat to all life on Earth, attempts to clean it up may cause even more harm.There are several steps that can be taken to help prevent water pollution from getting worse. Keep Machinery in Good Working Order The oil used to lubricate engines in all types of machines needs to be changed regularly. When
How to deal with water shortage problems? Water covers more than 70% of the Earth's surface and it is the most valuable resource in the world. We need water to live on this planet otherwise life on Earth wouldn't be possible. Many countries suffer from water shortages. There is no fresh water for people usage. It's actually a major problem in the world but what can we do to decrease this? Firstly, people need to realise that there are many other people in the world who does not have accessibility to water. We can decrease it by not wasting water on pointless things for example long showers and watering flowers outside the house. By doing this we will economize water and it may be possible for other people to use fresh water as well.
WATER POLLUTION THERE ARE THREE DIFFERENT WAYS THAT WATER CAN BE POLLUTED. ⦿ Surface Water Pollution - Most common type, you can visually see the pollution floating (plastic containers or oil and gasoline spills). ⦿ Ground Water Pollution – This becomes more relevant as it affects our drinking water. It become infected by toxic chemicals. ⦿ Microbial Pollution – Found in the countries who don’t have the facilities to cure the water so the bacteria and viruses grow in the water. The people have no other way of getting water so they are forced to drink it. WHAT CAUSES WATER POLLUTION? ⦿ Wastewater ⦿ Marine dumping ⦿ Industrian waste ⦿ Radioactive waste ⦿ Oli pollution ⦿ Underground storage ⦿ Global warming WHY IS IT A PROBLEM? ⦿ It causes worldwide disasters and deaths. ⦿ It may not damage our health immediately but can be harmful after long time.
TSUNAMI Kristjan Sillaots G1R2 WHAT IS TSUNAMI? A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore. WHAT CAUSES A TSUNAMI? These awe-inspiring waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will become a tsunami. WHAT CAUSES A TSUNAMI? Tsunamis may also be caused by underwater landslides or volcanic eruptions

Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today.
kilometres along the coast of Queensland. It consists of more than 600 islands. Most of the islands are uninhabited, but some have been developed as tourists resorts. Scientists estimate that the Reef is more than 30 millions years old and it had it beginning in a tiny animal known as polyp. There are more than 300 varieties of coral, which is a ultimate dream of every shell- collector. There are undersea observations, glass-bottomed boats and water scopes for undersea viewing, as well as skin-diving equipment. The Great Barrier Reef is and ideal place for a sunny holiday. The relief: Australia is an old and low continent with simple relief. Plains cover the greater part of the land. Most of the rocks have turned into sand and there are big sand deserts on the Western Plateau. In the centre of Australia are lowlands which are covered with sedimentary rocks. Deserts cover most of the land in Australia
Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution. But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air

The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a lot of energy inside them. Physics of wave energy To have a better understanding of the technical possibilities to harvest the energy out of waves to convert it into electric energy it may be helpful to have a look onto the physics of wave formation, the forces which attack and the

The perfect coffee. That is, to extract and put into solution, the coffee oils and the soluble (and semi-soluble compounds) that are formed when the coffee bean is roasted.18%-22% is the optimum extraction rate for good coffee. Under Extraction occurs when the brewing time is too short and not enough coffee soluble are extracted into solution. This can occur if the water is not hot enough or if the water passes through the ground coffee too quickly. An insipid, thin brew lacking in body and flavour will result. Over Extraction occurs when the water is in contact with the ground coffee for too long and too much of the coffee soluble are extracted than is desirable. A harsh tasting bitter brew will result. Freshness Coffee is best enjoyed as soon as it has been brewed. Oxygen in the atmosphere causes the taste to rapidly deteriorate and the beverage loses its aromatic oils and may soon

Modern issues It's 21st century, and we still have many issues, that need to be solved. Of course we can't solve all the problems. It is impossible, but at least we should give our best to try to solve these important modern issues. One of the biggest issues is access to clean water. 1st and 2nd world countries may not or don't have that problem at all, but access to a clean water is a serious issue for 3rd world countries. 3rd world countries might have an access to water, but not to clean water. It is important to have a clean water, because there are a lot of dangerous diseases in dirty water. It's a problem, which needs to be solved as quickly as possible. Another problem is an access to good food. About 21,000 people die every day of hunger, or hunger-related causes. This is one person every four seconds. Most of them are children. We already grow
water in motion. These soothing sounds and the beauty of colorful fish swimming among your plants, brings your landscaping alive. It's fun to create this attractive feature and it will become the centerpiece of your backyard. Before we get started I would like to answer some frequently asked questions about backyard ponds. · Will the winter cold kill my fish? Most fish will naturally stop eating and hibernate at the bottom of the pond when the temperature of the water goes below 45 degrees. If you live in a climate where the pond will completely freeze over (even at the edges) you will need to create a hole in the ice for the fish to remain alive. · Will the winter cold kill my plants? Yes, if it goes below freezing in your area. Bring plants inside for the winter months. · Do I need to filter the water? That will depend on your climate and the design of your system
Durability of concrete In this presentation I'm focusing on the durability of concrete. First I'll give a brief overview of concrete, we have to know what does it actually means and where is it used? (slide) Basically concrete is a construction material composed of cement, aggregate (generally gravel, limestone, or granite, plus a fine aggregate such as sand) also water, and chemical admixtures.(slide) Concrete is used to make pavements, architectural structures, foundations, roads, bridges, marine- and parking structures, brick/block walls and footings for gates, fences and so forth. Mainly it is used because of its high durability and availability, but also because it is cheaper than to use wood for example. Concrete is used more than any other man-made material in the world.(slide)
That’s why overweight wasn’t a problem back then. Their foodtable was more various because they ate everything what was edible and available in nature. Nowadays it’s very popular that people eat junkfood and different products that are full of chemicals, sugars and fat. And if they don’t move it’s easy to get overweighted. One of the main problems why humans are unhealthy is not drinking enough water. You can buy many different flavoured drinks nowadays that are full of artificial colours and sugars. Drinking water is geting very unpopular especially among young people. Human body needs water to work proparly. One of the problems why we don’t have enough water in our bodies is alcohol. People drink cold alcoholic drinks in summer instead of water but alcohol carries out water from our bodies.To start living healthier, stay hydrated.

Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains
diseases. 2. Jobs created by tourism are often poorly paid and seasonal. Tourism can push up local property prices and the cost of goods and services. 3. A huge amount of tourism returns are taken away from the target country. There are many reasons: quarters with a foreign heritage, travel agency, commercial expences and raw materials for the tourists. ENVIRONMENT 1. Pollution The cruise ships of the Mediterrean Sea are polluting water and coast areas and the bottom of the sea. One cruise ship creates about 50 tons of solid garbage a year. There are floating plastic garbage islands in the ocean. 2. Air transport is the most polluting transport type. Plane flings carbon dioxide and other pollution to the atmosphere. 3. Biodeversity Due to humans about 500 plants are extincting by the Mediterrean Sea. In the water the divers can damage coral reefs. 4
Reuse- Use thing that you have already got or give them to people who need those things. For example: glothes, use newspaper as a wrapping paper. Recycle- recycle thing. It does not take too long and it makes so much differencs Saving energy and your money Save electricity - people use a lot of electricity only because they forget or leave electrical appliances on. How: unplug everything that you do not use and do not forget to turn the light off Save water - Wasting water wastes electricity wich wastes energy. How: repair all leaky water mechanisms and if possible take shorter showers Saving energy and your money Save gasoline- It takes a lot of energy to operate a car. How: use other healthier alternatives like bicyclel or walking, but even using public transport helps reduce gasoline usage Save heat-It takes a lot of energy to heat houses and water. How: wear warmer clothes, if possible do not use hot water unnecessarily
We Do Not Inherit the Earth From our Ancestors; We Borrow It From Our Children Some of the people think that the Earth is like something, that we can take and it will grow back like apples every summer on trees. But I do not think it does. I think we borrow it from the future. Firstly we are using too much water nowadays. We are wasting it and not thinking about the future, but we should. Lately the media has started to speak more about the need for clean water, specially in some parts of the Earth. In the past people did not have showers or baths, toilets with water, dishwashers. These and many other things use more water, than people used to. Secondly we are producing a lot more, than we maybe should. It seems like the most meaningful thing nowadays is money. Maybe because of that we are over producing. If we look at the landfills we can see how full they are. I think it is that way because we produce too much and use too much packages
Made up of familiar foods that you tolerate well A grilled chicken sandwich or a slice of cheese pizza might fit the pregame meal description, but stay clear of the fried food (including french fries), greasy burgers, and soft drinks. Why is it so important to drink plenty of liquids during exercise? Water acts as your body's cooling system. You don't want to get dehydrated. The best way to stay hydrated is to drink plenty of fluids with meals, and drink about 2 cups (16 ounces) of water 2 hours before exercise. Is it better to stay hydrated with sports drinks or plain water? Water is often enough. But if you're exercising for more than 60 minutes in hot, humid conditions, sports drinks may help. They give you carbs and sodium, as well as fluids. Sports drinks are also a good choice if you play team sports like soccer or football, especially when the temperature and humidity are high. If you sweat a lot, a sports drink might be preferable to water.
One solution would be to use more hydropower. In 2005, renewable energy represented one-fifth of total power generation. Hydropower is the most advanced of the renewable and represents 87% of this production. 160 countries all over the world are using hydropower. Five countries make up more than half of the world's hydropower production. Those countries are: Brazil,Canada, China, Russia and the USA. (Production) *Most of the energy comes from the potential energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. *Pumped storage hydroelectricity produces electricity to supply high peak demands by moving water between reservoirs at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the reservoir. And when there is a big demand, like in the evenings, then the water is

• Human population has been rising continuously since the end of the Black Death, around the year 1350 • The most significant increase has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity • The recent rapid increase in human population over the past three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are either unreachable or too polluted, leaving less than 1% of the world's freshwater, or about 0.003% of all water on Earth, readily accessible for direct human use. • According to the Global Outlook for Water Resources to the Year 2025, it is estimated that by 2025, more than half of the world population will be facing water-based vulnerability and human demand for water will account for 70% of all available freshwater.

Technology. I'd like to talk about environment, its pollution and protecting. I shall only take 3 minutes of your time. Let me begin with the word enviroment and what it means! It means surroundings in which people, animals and plants exist. These are the things that we need, to be alive, but they are also many man-made things and technical progresses that harm the nature. Therefore we can´t live on this planet without basic components which are needed for human existence - air, water and soil. Firstly air, which is mostly a mixture of oxygen and nitrogen. People, animals and plants can ´t live without air. Without oxygen there would be no fire. So we can see, that air is the basic condition for life on the Earth. Did you know that till 18th century people didn´t know composition of the air? They only used the knowledge of moving the air. Turning to water which covers over 71 % of Earth´s surface. It is also in underground and, naturally, in the air
differences in solubility, determining the percentage of table salt in a sand-salt mixture. Used compounds Solid sodium chloride in a mixture with sand, dried to a constant weight at 105ºC. Equipment Beaker, glass rod, funnel, conical flask, measuring cylinder (250 cm 3), hydrometer, filter paper. 1) In a conical flask, dissolve the NaCl from a previously weighed sand-salt mixture. To do that, add about 50 cm3 of distilled water to the mixture. Stir the solution with a glass rod and then filter it. For filtration, fold the filter paper in half twice. Cut one corner for the filter paper to distribute evenly to the wall of the funnel (see Figure Figure 1.1 2.1 figure 1.1). Place the filter paper into the funnel, wet it with distilled water and press it firmly against the wall of the funnel. While filtering, try to
