The Origin of the Winds Mobiles: Art in Motion S Soci cien al S & ce tudies e nc Wind Farms Going Offshore A rt Sci e Wind Why Does Wind Blow? www.frenglish.ru WIND Science Why Does Wind Blow? a sail Background Link Wind is fast-moving air It affects things around us in many ways the eye of a typhoon A boat’s sails catch the wind When the wind blows, the sailor adjust the sails so that the boat moves forward pollen A typhoon is a strong storm It has wind that moves very quickly The wind spins around an “eye” located at the storm’s center These storms can a lot of damage Some flowers use wind to spread seeds Their pollen is light enough to be carried by the wind Rice, wheat, and corn all use wind to spread seeds Key Words spin surface 10 heavy ability pressure opposite dense occur Vocabulary Worksheet → p 117 34 Lesson • Wind 35 WIND 11 Science www.frenglish.ru Why Does Wind Blow? Let s Focus What makes a kite fly? What makes a pinwheel spin? The answer is wind Wind is another name for during the day moving air What makes it move? When the sun warms up land, the air above the land gets hotter As a result, this air becomes lighter and rises up The empty space left by the rising air needs to be filled So, cooler, heavier air rushes in to fill it This rushing air is wind after sunset Wind also blows because of differences in air a pinwheel pressure Air pressure is the weight of air molecules 10 Hot air molecules are light and move farther apart, The earth’s surface is composed of land and sea, so they cause low pressure On the other hand, cool which have different heating abilities Land takes less air molecules are dense and come closer together, so time to heat and cool than sea During the day, air over they cause high pressure Wind blows from areas of high pressure toward areas of low pressure 15 land heats up very quickly It creates low pressure on land while there is still high pressure over sea This 20 causes air to blow from sea toward land However, after sunset, the opposite occurs The air above land cools down quickly, causing high pressure That’s why the night air blows from land toward sea Next time you’re near the ocean, try to feel which way the wind 25 is blowing Words 233 low pressure high pressure Wind blows Cooler, heavier air goes down Hotter air rises up In Other Words 36 space area Lin to Text How does the direction of wind change near the ocean? rush move quickly be composed of consist of create cause Lesson • Wind 37 www.frenglish.ru Reading Comprehension Graphic Organizer & Summary Step 1 What is this passage mainly about? Complete the information with the words from the box a how wind changes our landscape b how wind is formed and the way it moves c how people use wind in their daily lives • The What happens to air as it warms up? a It turns into water b It gradually sinks c It rushes to fill empty space d It becomes lighter and rises up rises • When land warms up, the air above it How Wind Is Made d why wind is needed and how it is created Wind and Air Pressure space is filled by cooler air • Hotter air causes low air pressure • Cooler air causes high air pressure • Wind What is NOT true about wind and air pressure? empty blows from areas of high pressure to areas of low pressure a Hotter air creates low pressure b Cooler air is heavier than warmer air Wind between Land and Sea c Wind blows from areas of lower pressure d Differences in air pressure cause wind • Land heats up and cools down faster sea • During the day, wind blows from • After sunset, wind blows from than water land What is mentioned about land and sea? a Air over land causes low pressure after sunset b Land heats up more quickly than sea c Wind blows toward land at night Step d Land takes longer to cool than sea does What happens when warm air rises up and leaves empty space? Then cooler [cool] , heavier [heavy] air rushes in to fill it land toward sea Moving air is known as rises Near the sea, which way does wind blow after sunset? At night, wind blows from Complete the summary with the words from the box Then cool air is made A difference in air wind When the earth heats up, warm air rushes pressure in to fill the space This is how wind makes wind blow Air pressure is the weight of air molecules Hot air causes low air pressure, while cold air causes the pressure to increase Near the sea, the Find Evidence What CANNOT be inferred from this passage? a Wind can travel in different directions direction of the wind changes between daytime and nighttime During the day, air blows from sea toward land In contrast, air blows the opposite way after sunset b Air moves from high pressure to low pressure c Warmer air molecules cause air pressure to increase d Different parts of the earth’s surface heat at different speeds Go to the passage and underline the evidence for your answer (lines 11-12) Hot air molecules are ~ cause low pressure 38 Lesson • Wind 39 www.frenglish.ru nc tu Scie e dies WIND & Social S Wind Farms Going Offshore Background Link Solar Energy Using solar panels, we can capture sunlight and make electricity Renewable energy is energy that comes from resources that we never run out of Because it is renewable and produces less pollution, it is considered the energy of the future What are some examples of renewable energy? Geothermal Energy Electricity is generated from the earth’s heat Tidal Energy Using the power of the ocean tides, generators turn the movement of water into electricity Key Words electricity ruin Wind Energy Huge wind turbines use the power of the wind to make electricity 12 generate landscape renewable solution plentiful productive Vocabulary Worksheet → p 118 40 Lesson • Wind 41 WIND 13 Science & Socialwww.frenglish.ru Studies Wind Farms Going Offshore However, wind power has downsides, too On days with no wind, the turbines don’t generate any electricity Also, some people think wind farms are noisy and ruin the landscape These problems have led scientists to look for new solutions 20 One possible solution is to move Let s Focus wind farms offshore Offshore wind farms are very productive since ocean winds Have you ever imagined the world without are strong and steady Countries such as electricity? What if we used up all of our energy? the UK, Germany, and China have already Many countries have started searching for better of wind power For example, the Walney Extension in the UK generates enough electricity to power 600,000 homes The Wind can be used to generate electricity with the future of wind power looks quite promising help of wind turbines A wind turbine is a tall tower with large blades When wind blows, the blades spin 30 The spinning blades turn a generator Words 228 This turns a generator that makes electricity To create more electricity, many wind turbines may be built in 25 started producing energy from this type sources of energy Wind power is one of the most attractive options Wind makes the blades spin 10 one area This is called a wind farm a typical wind turbine The number of wind farms is increasing because wind power is clean and renewable Wind turbines don’t require fuel or create any dangerous gases or waste Plus, wind is a free and plentiful resource In Other Words 42 require need downside disadvantage Lin to Text Why is wind power an attractive option? 15 steady constant promising bright Lesson • Wind 43 www.frenglish.ru Reading Comprehension Graphic Organizer & Summary Step 1 What is this passage mainly about?
