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.

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.

A meteorologist is a scientist that studies weather. The person on the news that tells us the weather is a meteorologist.

Tools to measure weather Rain GaugeObservationWind VaneThermometer

Used to look at the sky to see if it is cloudy or sunny.

A tool used for measuring temperature. Temperature is how hot or cold something is. Try to dress the bear in the proper clothes to go outside by reading the thermometer.

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.

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 3. Precipitation 1. Evaporation 2. Condensation The sun warms the water and air. The water will evaporate and change into water vapor. The water vapor meets cooler air and then it will condense, or change into tiny drops of water. The drops of water form clouds. The water drops join and get heavier. They fall to Earth as precipitation.

tune of She’ll be coming around the Mountain 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.

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.

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.
