Why Sky Watch? Click on the meteorologist Audience of learners: *K-3 Science class in a suburban setting *Weather Unit/Physical Science *The focus is on: Weather components and clouds *Simplify & extend concepts on weather *This project will serve as: reinforcement for calendar, astronomy, and physical science concepts. Check out our school’s website! • The learner will identify elements in the sky (their position, shape, and change of matter) to predict weather conditions. • The learner will utilize their appropriate senses in describing weather conditions. • Generate questions based on these senses. The science of the atmosphere, of weather and weather conditions. – – – – Air Masses Wind Precipitation Cloud Cover To track the weather look below and find, weather words & pictures to keep in mind. Moist, warm air An air mass is a huge body of air that can form over land or water. Air over Water = Moist, warm air Air over Land = Cold, dry air Warm Front 1) Warm air pushes cold away Warm Front Cold, dry air Cold Front 2) Cold air rises beneath the warm air Cold Front Tell me more. Wind is moving air. The force and direction of the wind gives us a better indication of weather conditions outside. By knowing how strong and in what direction the wind moves, we can often classify the type of wind as a breeze, a gale, a storm, tornado, or a hurricane. Go on a windy day adventure! Can you feel the push of the wind pulling you in a particular direction? Wind can be very powerful and can work to make storms even stronger. Show me more. Precipitation is a deposit on the earth of hail, mist, rain, sleet, or snow; also, the quantity of water deposited. The type of precipitation that falls from the air is dependant on the temperature of the air the water falls through. Air (High Temperature) Rain Air (Very Low Temperature) Snow Air (Passing Through Layers of Temperatures) Melted Rain, Sleet, Hail • Any visible mass of water droplets, ice crystals, or a mixture of the two that is suspended in the air, usually at a considerable height. • Clouds are defined by their appearance. How do the appearance of clouds affect weather forecasts? • • Clouds create lower temperatures during the day if the clouds are thick and widespread enough to block heat from the sun. Clouds create higher temperatures during the day if the clouds are thin and the sun is able to provide heat. Practice Meteorologist Skills Which of the following represents precipitation? A) SNOW B) WIND C) CLOUDS • Weather term was not identified correctly. Let’s Review! Try again • Weather term was correctly identified. Which of the following represents air masses? A) Breeze B) Cold Front C) Mist • Weather term was not identified correctly. Let’s Review! Try again • Weather term was correctly identified. Which of the following represents cloud cover change? A) Thin B) Thick and Widespread C) Damp Further Explore Cloud Cover • Weather term was not identified correctly. Let’s Review! Try again • Weather term was correctly identified. Ready for the Meteorology Exam! Compare weather to sky and cloud colors. For example, under what weather conditions is the sky the brightest blue? the darkest gray? What is the most frequently observed cloud color just before it starts to rain? snow? • • • Does the sky/cloud color(s) change during the day? Does the sky/cloud color change from season to season? Does the sky/cloud color(s) change from one part of the sky to another? Return to Types of Cloud Ready for the meteorology exam! Outside the ground is damp, and wet droplets are falling from the air. It is… A) Windy B) Foggy C) Rainy • Your prediction is incorrect. Let’s Review! Try again • Your weather skills are on track. Way to be a great meteorologist!

Way to be a great meteorologist! • R-e-v-i-e-w, It’s time to review! • The slides that follow will help summarize the content presented through the Sky Watch: Weather presentation tool. Retry the Exam Tell me more. • Weather components include but are not limited to… Air Masses Wind (force and direction) Precipitation Cloud Cover Air Mass Wind An Air Mass is a huge body of air that can form over land or water. Air movement can result in warm or cold fronts. • Wind is moving air. • There are differing degrees of wind (force and direction). • Precipitation is any form of water that comes out of the Precipi- atmosphere to the ground. • These include: rain, snow, sleet, and hail. tation Cloud Cover • Clouds can take on differing appearances. • Clouds form as air rises, expands, and cools.
