1. UNIDAD DIDÁCTICA: EL TIEMPO CURSO:4º PRIMARIA ÁREA: CONOCIMIENTO DEL MEDIO EN INGLÉS OBJETIVO: introducir al alumno de forma amena e interactiva en el conocimiento del tiempo atmosférico, los elementos que lo componen, los instrumentos que se utilizan para medirlo y las implicaciones que éste tiene en la vida cotidiana. Mª Teresa Cayuela CEIP Salvador Dalí Villalbilla

4. W hat´s the weather? 1.- temperature 3.- precipitations It is the state of the atmsphere at a given time and place with respect to variables as ... 2.- wind velocity Measuring weather People who study weather are meteorologist They use tools artificial satellites get information about weather Weathermen gather information and predict weather thermometer rain gauge wind vane barometer anemometer hygrometer Making weather forecast expansion.com

11. Wind Sock M ake your own wind sock to hang on the porch, then watch it dance and swing as it catches the breeze. Wh at You'll Need: * One 26-ounce-size plastic coffee can lid * Blunt scissors * 2/3 yard of nylon material * Tape measure * Permanent markers * Needle and thread * Cord Step 1: Have an adult cut the center out from the plastic coffee can lid to make a rim. Step 2: Cut a piece of nylon 15 inches wide on one end, 17 inches wide on the other end, and 12 inches long. Decorate the fabric with permanent markers. Step 3: Sew the 12-inch long ends together to form a tube. Fold the 17-inch wide end over the plastic rim. Sew a stitch around the rim to secure it. Step 4: To add streamers, cut four 1 1/2 × 24-inch strips of nylon. Sew them to the 15-inch-wide end of the wind sock. Step 5: To hang the wind sock, cut a 12-inch piece and a 15-inch piece of cord. Carefully cut two small holes in the fabric on opposite sides at the 17-inch-wide end. Tie on the cords, then tie the ends together. Hang it from the porch so that it is slightly angled to catch the wind. You won't need a weatherman to tell you how hard the wind is blowing with the next weather experiment.

12. 1.-The surface of the earth is heated by light energy from the sun 2.-warmed surface 3.- the warmed surface on Earth heats the air above 4.-When the warmed air is up, the wind cools down the temperature and cools the air 5.-the cold air goes down again 6.-SEA BREEZE EXPLAIN THE DRAWING ABOVE: 1.- ___________________________________________________________________________ 2.-____________________________________________________________________________ 3.-____________________________________________________________________________ 4.-____________________________________________________________________________ 5.-____________________________________________________________________________ 6.- What effect do the sea breeze produce in that cycle? explain your idea. _____________________ ______________________________________________________________________________ METEOROLOGISTS USE TOOLS TO STUDY AIR TEMPERATURE

13. People who study weather They gather information, predict the weather (make weather forecast) They use tools in order to make weather forecast Meteorologist or weathermen air temperature · depends the season: during the summer months- · the most direct light on Earth · There also more hours of daylight · the Earth´s surface has more time to heat up · The angle of sunlight is much less direct · Solids(land) absorb the sun´s energy quickly than areas cover by water. · the air obove solids is warmer as well. · Land areas close water tent to be cooler than those that are father inland. · The surface of Earth is heated by light energy from the sun. · The heat energy from the warmed surface on Earth heats the air above. air pressure wind · meteoroligists use thermometer to measure temperature · It is the amount of pressure exerted by the weight of the earth´s atmosphere · Living things don´t feel air pressure ·Changes in air temperature cause changes in the air pressure · Low pressure area · High pressure area humidity · can be · as warm air rises, there is less pressure on the surface of the earth · air has weight · The air pressure is different in each place.It depends the amount of heat that each place recives · cooler air moves down · Cool air is heavier than warm air. · cool air exerts more pressure on the surface · meteoroligists use barometers to measure air pressure · the moving air · Meteoroligist use a wind sock or a wind vane to know direction the wind is coming · The arrow of the wind vane tells us the wind is coming from · Meteorologist use anemometers to measure the speed of wind They have to study: · how much water is in the air · When the air is dry, the evaporation of water increases. · When the humidity is hight in the air, the chance of rain or snow increases. · meteorologists use hygrometers to measure humidity
