S1E1 Students will observe, measure, and communicate weather data to see patterns in climate and weather. a. Identify different types of weather and the characteristics of each type. b. Investigate weather by observing, measuring with simple weather instruments (thermometer, wind vain, rain gauge), and recording weather data (temperature, precipitation, sky conditions, and weather events) in a periodic journal or on a calendar seasonally. c. Correlate weather data (temperature, precipitation, sky conditions, and weather events) to seasonal changes.
What is Weather? • Weather describes what the air outside is like. • When the air outside changes the weather changes. • Weather describes any precipitation that might be in the air.
How are these kinds of weather different?
Who studies weather? A meteorologist is a scientist that studies weather. The person on the news that tells us the weather is a meteorologist.
Observation • Used to look at the sky to see if it is cloudy or sunny.
Thermometer • A tool used for measuring temperature. • Temperature is how hot or cold something is. http://www.fossweb.com/modulesK-2/AirandWeather/index.html Try to dress the bear in the proper clothes to go outside by reading the thermometer.
Wind Vane A wind vane, also called a weather vane is used to measure the direction of the wind. The large side of the arrow catches the wind and causes the arrow to spin pointing in the direction the wind is blowing.
Rain Gauge • A rain gauge is used to measure precipitation. • Precipitation is any form of water particles, either liquid or solid, which falls from the sky and reaches the ground.

The Water Cycle The water drops join and get heavier. They fall to Earth as precipitation. The water vapor meets cooler air and then it will condense, or change into tiny drops of water. The drops of water form clouds. 2. Condensation 3. Precipitation 1. Evaporation The sun warms the water and air. The water will evaporate and change into water vapor.
The Water Cycle Song tune of She’ll be coming around the Mountain Water travels in a cycle, yes it does. Water travels in a cycle, yes it does. It goes up as evaporation. Forms a cloud called condensation. Comes back down as precipitation. Yes it does.

Definitions Clouds- A visible collection of tiny water droplets or, at colder temperatures, ice crystals floating in the air above the surface. Clouds come in many different sizes and shapes. Clouds can form at ground level, which is fog, at great heights in the atmosphere, and everywhere in between. Clouds offer important clues to understanding and forecasting the weather. Condensation- The change of water vapor to liquid water, as when fog, dew or clouds forms. Evaporation- The process of changing a liquid (like water) to a vapor. It’s the opposite of condensation. Meteorologist- is a scientist that studies weather. Precipitation- General name for water in any form falling from clouds. This includes rain, drizzle, hail, snow and sleet. Rain Gauge- A tool used to measure rainfall. Can also be used to measure snow, sleet, and hail after it melts.
Definitions cont. Temperature- The measurement of how hot or cold something is. Thermometer- The instrument that measures temperature. Water vapor-is water you can not see in the air. Without it we would have no clouds, rain, or snow. 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. Wind- moving air. Wind Vane- A tool used to measure the direction of the wind.
