Weather instruments

  1. 1. • Have you ever wondered why it sometimes rain in one place but not in another place? • Did it ever occur to your mind why we have storms and why people can easily track their location and speed? • What do you think is the phenomena behind it? That is all because of weather. Now, I want to know what is your idea of weather or what comes to your mind when you hear the word weather.
  2. 2. • Use the cloud 3 drops to note your ideas. You will be given 5 minutes to work on this on your notebook. Processing: 1. Where did you get this idea about weather? 2. Why did you say that weather is or has something to do with ________? 3. Do you know what will be the kind of weather today? tomorrow? next day?
  3. 3. • Studying about the weather is important because it affects our day to day activities. • That is why, people must be aware of the daily weather so that they can plan things well. So, what is the meaning of weather? Let us read and study this sample weather forecast or news.
  4. 4. Read the sample weather forecast. • No major weather disturbance will affect the country which will continue to experience fair weather except for scattered rain showers over Bicol region, Eastern Visayas and Mindanao. Light easterly to southeasterly winds will prevail throughout the archipelago and coastal waters will remain slight. • Metro Manila- partly cloudy with range of temperature- 22 – 35 • Metro Cebu- Cloudy skies, temperature- 26 – 31 • Metro Davao-partly cloudy, temperature- 24 -34 • Baguio- partly cloudy, temperature- 14 – 26 • Sunrise-5:56 A.M., Sunset- 6:08 P.M. Processing: 1. What is the weather forecast for the country today? 2. Which areas of the country will experience rain? 3. What is the direction of the wind? 4. Which place will experience cold weather? 5. What area will experience the highest temperature today? 6. Is weather condition the same in all the places? 7. What is weather?
  5. 5. • Weather - It describes the condition of the air at a particular time and place. Weather also tells how the air moves (wind) and describes anything it might be carrying such as rain, snow or clouds. Thunder, lightning, rainbows, haze and other special events are all part of weather. What is weather?
  6. 6. weather ??? • It is about the atmosphere • It is a condition • It keeps changing any time of the day • It varies from place to place • It has a lot of elements Weather is the condition of the atmosphere at any given time. How does weather differ from climate?
  7. 7. • Climate - It describes the average weather conditions in a certain place or during a certain season. Weather may change from day to day, but climate changes only over hundreds or thousands of years. • Many animals and plants need one kind of climate to survive. Dolphins and palm trees can live only in a warm climate, while polar bears and spruce trees need a cold climate. What is climate?
  8. 8. Now, look at the pictures below. Which among the pictures below shows a weather man? Processing: 1. What made you say that he is a weather man? 2. What does a weather man do? 3. In science, what do you call a weather man? A DCB
  9. 9. What do you call the person who study the weather? We call them Meteorologist. Everybody say METEOROLOGIST. What does he do? Meteorologist study the weather. He gathers information and reports it to the people. He also helps trace weather disturbances through the use of different weather instruments.
  10. 10. • Have you seen some weather instruments that are being used to help the meteorologist tell the daily weather condition of a place? • Do you know how to use them? • Let’s do this matching type activity for me to know whether you really know them or not. • In your notebook identify the following materials by writing their names. Choose your answers from the box below. You are given 3 minutes to do this activity. READY???

  12. 12. • Using a variety of weather instruments, maps and reports, meteorologists study the ever- changing weather information in order to discover trends and patterns which help them forecast the weather for the next few hours and days. • Meteorologists can now give advance warning on extreme weather conditions so that communities can prepare for the worst.
  13. 13. So, what are the different weather instruments they use to gather information? • Air thermometer • Anemometer • Wind vane • Wind sock • Hygrometer • Compass • Barometer • Rain gauge • Weather maps • Weather balloon • Weather satellites
  14. 14. Air thermometer • Use to measure air temperature • It is a hollow-glass tube with a liquid (alcohol or mercury) inside. • When the air temperature is high the liquid inside expands or goes up but when the air temperature is low the liquid goes down.
  15. 15. Anemometer • Measures wind speed • The cups catch the wind, turning a dial attached to the instrument. The dial shows the wind speed.
  16. 16. Wind vane • an instrument that determines the direction from which the wind is blowing.
  17. 17. Weather balloon • measures weather conditions higher up in the atmosphere through a radar.
  18. 18. Hygrometer • Measures the water vapor content of air or humidity Sling Psychrometer measures relative humidity, using the cooling effect of evaporation. Two thermometers are used in a sling psychrometer.
  19. 19. Barometer • Measures air pressure • It tells whether or not the pressure is rising or falling. • A rising barometer means sunny or dry conditions, while falling barometer means stormy and wet conditions.
  20. 20. Rain gauge • Measures amount of rain that has fallen over a specific time or period.
  21. 21. Compass • is a navigational instrument for finding directions.
  22. 22. Weather maps • Indicate atmospheric conditions above a large portion of the Earth’s surface.
  23. 23. Weather Satellite • It is used to photograph and track large- scale air movements such as typhoon, hurricane etc.
  24. 24. Processing: • What can you say about the different instruments used by meteorologist? • Do you think they are really helpful? • If you were a meteorologist which among the instruments will be your favorite? Why? • How do you think people in the past tell about the weather? What instrument do they used? OUR EYES are one of the best ways to help detect the weather. Always keep an eye at the sky and you'll usually be on top of weather conditions.
  25. 25. It is really fun to know these different instruments. Did you know that different countries have their own weather stations? Weather station is the place where all data about the weather are being gathered and evaluated. They are also the one who is responsible in informing the people about the daily weather condition of the country. In the Philippines we also have our own weather station. Do you know what is it?
  26. 26. In the Philippines we have a weather station that gives the daily weather report and observation we call it PAGASA. What is the meaning of PAGASA? Philippine Atmospheric Geophysical and Astronomical Services Administration. Memorize it kids!!!
  27. 27. • PAGASA is a Philippine national institution dedicated to provide flood and typhoon warnings, public weather forecasts and advisories, meteorological, astronomical, climatological, and other specialized information and services primarily for the protection of life and property and in support of economic, productivity and sustainable development.
  28. 28. • Let us see if you really learned something today? With a partner (pair share), complete the concept map below in your notebook. You are given 10 minutes to do this. Then, be ready to share your work to the class. WEATHER MEANING INSTRUMENTS (1-5) PERSON PHIL. WEATHER STATION
