First Grade Unit Two Weather (Same as Unit One) TLW describe weather conditions, identify tools for observing and recording weather change, and describe how the Sun warms the Earth and causes weather to change over the seasons. (Gist: Weather - Sun Warms the Earth) Enduring Understanding(s) In Michigan, the seasons are summer, autumn, winter, and spring. Plants need sunlight and warmth to grow. Severe weather can be dangerous and precautions must be taken to stay safe. The Sun warms the land, air, and water, affecting the weather. Tools used to measure temperature, precipitation, cloud cover, wind. Weather changes daily and seasonally. Weather is described by determining temperature cloud cover precipitation and wind. Essential Questions How do people stay safe during severe weather? How does weather change? What causes our weather? What tools do we use to measure weather?

The atmosphere is a "blanket" of air around Earth, made of gases including oxygen. Weather conditions include temperature, amount and type of cloud cover, precipitation, wind, and humidity. Each year brings four different seasons: spring, summer, fall (autumn), and winter. Changes in the seasons occur in an observable pattern. In many places on Earth, including Michigan, each season of the year is characterized by unique weather conditions. Weather affects what people do and wear in different seasons. Students relate seasons to what plants and animals do. The change from season to season is designated by specific dates on the calendar but actually occurs through a more gradual change in temperature and precipitation over time. Precipitation is rain, snow, freezing rain, and hail. (Dew is not considered to be precipitation because it does not fall from the sky, but it is condensed moisture [water vapor] which comes from the atmosphere.) Severe weather includes thunderstorms, lightning, tornadoes, hurricanes, high winds, blizzards, extreme cold, and heat waves. Safety precautions are important to take during severe weather. Especially in Michigan, where thunderstorms, tornadoes, and blizzards occur frequently, students should understand what measures they and their families should follow to ensure their safety. Thunderstorm: Thunderstorms are storms with lightning and thunder. They have gusty winds and heavy rain. They can occur in any season, but are more common in spring and summer in Michigan and in the afternoon or evening hours. Lightning: Lightning is a bright flash of electricity produced by a thunderstorm. Tornado: A tornado is a windstorm that happens over land and has a funnel-shaped cloud that extends and touches the ground. (If it does not touch the ground it is referred to as a funnel cloud, not a tornado.) Winds can be 40 mph to over 300 mph. Tornadoes usually last five to ten minutes, although some have lasted as long as an hour. They usually happen between the months of March and August in Michigan. There are close to 1,000 thunderstorms in the U.S. every year. Most of them (75%) are weak. Blizzard: A blizzard is a winter storm with large amounts of falling or blowing snow and very strong winds (greater than 35 mph) for an extended period of time (greater than 3 hours). Clouds are made of tiny drops of water/ice. The water is released when precipitation occurs. Cloud cover varies from day to day, from clear to partly cloudy, cloudy, or foggy. (Extension: Major cloud formations are: cumulus - fluffy usually associated with pleasant weather; cirrus - high feathery, white clouds of ice indicating weather changes; and stratus - flat, low-lying clouds associated with rain or snow.) The Sun is the most important source of heat that warms the Earth’s land, air, and water. The Sun’s light and heat helps plants grow. (Extension: Evaporation involves heated water vapor rising, resulting in change from a liquid to gas. Condensation involves the cooling of water vapor, resulting in a change from gas to liquid. Clouds and fog form by this process. Water forming on the exterior of a cold glass in summer is an example of condensation.) Real World Connection How do I dress for recess? Safety precautions during severe weather (taking shelter for a tornado, driving more slowly or staying off the roads during a blizzard, staying in for recess during extreme cold, avoiding standing under a tree during a thunderstorm) Common Misconceptions Students may think that the Sun has nothing to do with the weather. Students may think that standing under a tree is a good place to take shelter during a thunderstorm. Lesson Ideas: 1. TLW observe, record, graph and compare daily changes in the weather, relating weather conditions to seasonal changes.CCSS/CE(s): E.ES.01.21; E.ES.01.22; E.ES.01.31; E.ES.01.32; S.IA.01.12; S.IP.01.11; S.IP.01.12; S.IP.01.13; S.IP.01.14; S.IP.01.15; S.IP.01.16; (Resources: Daily Weather Conditions; Seasonal Symbols; Seasonal Signs and Symbols; Seasonal Changes; Trees) Suggestion: Start this unit in early fall and keep a log of daily weather one week per month. Collect weather data such as temperature, cloud cover, precipitation, wind, and outdoor conditions (e.g., changing leaf color, snow piles along the sides of roads). Use a Kestrel 3000 Pocket Wind Meter (http://www.ambientweather.com/ , $129.00) on trips around the school and community to collect weather data. This will be a year-long activity in which the class will make a booklet of their data for each of the seasons. (Use seasonal symbols in the resources for large group discussions and bulletin boards that can be shared during parent-teacher conferences.) Draw conclusions based on data collected to identify weather conditions for the four seasons. In the spring, conclude the unit by analyzing weather patterns and determining weather conditions for the four seasons. Use a digital visual presenter (e.g., Elmo) and Resource: Daily Weather Conditions (or make a transparency and use an overhead projector) and record weather data as a class. Changes should be related to temperature (cold, hot, warm, cool), cloud cover (cloudy, partly cloudy, foggy), precipitation (rain, snow, hail, freezing rain), and wind (breezy, windy, calm). Daily changes in the weather may include cooler at night and warmer in the daytime, variation in cloud cover and changes in precipitation throughout the day and from day-to-day. Identify tools that might be used to measure temperature (thermometer), precipitation (rain gauge), cloud cover (estimate), and wind (wind sock). A flag or string held in the air can be used instead of a wind sock to determine wind direction and strength. First grade mathematics includes bar graphs (See Kindergarten Mathematics Academic Standard: Data and Probability - Real and Picture Graphs). To integrate math and science, possible bar graphs for this science lesson could include bar graphs of daily temperature in the morning and afternoon (or at night based on media weather reports). Students may illustrate an activity associated with a particular season and name the season. Read The Seasons of Arnold’s Apple Tree by Gail Gibbons (ISBN-10: 0152712453 ISBN-13: 978-0152712457) and have students create a sequence of seasonal pictures (Resources: Seasonal Signs and Symbols; Seasonal Changes). To differentiate for students who may still have difficulty with drawing, students may use the illustrations from Resource: Seasonal Symbols or other sources. 2. TLW describe typical weather conditions for each season as related to Michigan's climate. CCSS/CE(s): S.IA.01.12; S.IP.01.11; Summer - warm, occasional rain showers, thunderstorms, hot and humid at times, mostly sunny Fall - cooler, windy, rain, many cloudy days Winter - cold, snow, lots of cloudy days, freezing rain Spring - warming days but still cool, rain, tornado season, more potential for severe weather Watch and observe how one tree changes over the year. 3. TLW collaboratively discuss and describe appropriate clothing and accessories to use in various weather conditions and justify the selection.CCSS/CE(s): E.ES.01.22; S.IA.01.13; S.RS.01.11; Include waterproof clothing as a need for some weather conditions. Make a connection to community workers studied in first grade Social Studies. 4. TLW describe severe weather characteristics and create an action plan for safely surviving severe weather conditions at school and at home.CCSS/CE(s): E.ES.01.23; E.ES.01.24; S.IA.01.13; (Resources: Weather Watch; Being Safe During Severe Weather Conditions; Our Family Plan) Include characteristics of thunderstorms, lightning, tornadoes, strong winds, blizzards, and hurricanes. There is no need to focus on hurricanes, but many children will be aware of hurricanes due to the news or having relatives or family friends who live in regions affected by hurricanes. Discuss how all but hurricanes are likely to be severe weather conditions in Michigan. Safety in severe weather includes listening to weather media and adults. http://www.nws.noaa.gov/om/severeweather/ Click on thunderstorms, tornadoes and floods for excellent brochures for families regarding safety precautions. http://www.lightningsafety.noaa.gov/ Discuss Michigan's severe weather and safe places to go. Safety ideas will be limited to safe areas to go and places to avoid in each of these severe weather events as applicable. a. Thunder and lightning - Go inside a sturdy building if you can. If you are in a car, stay in the car. Do not use the telephone or computers. If you cannot go inside, stay away from tall buildings or trees. Do not go into pools, lakes, or other bodies of water. b. Tornadoes or strong winds - Go down to a basement or into a room that is in the center of the building. Get under a sturdy piece of furniture. Stay away from windows. Get out of cars or trailer homes. c. Blizzards - At home, stay inside. If outside, get to a shelter. In a car or truck, stay inside. Run the car for about 10 minutes each hour for heat. Exercise to stay warm. d. All storms - Flashlights should be used instead of candles when the power goes out. Stay away from fallen power and utility lines. Stay off the phone or computer. http://www.nws.noaa.gov/om/brochures/owlie-lightning.pdf for an age-appropriate brochure explaining lightning and other storm precautions The informational text article (Resource: Weather Watch) is included as a teacher resource or for differentiation with students who already read well. It can be read aloud to students or used for teacher background information. The questions can be used with first graders as discussion questions rather than multiple choice. Note: Use discretion when teaching young children about severe weather events. Some children can be traumatized by graphic descriptions of these destructive weather phenomena. 5. TLW identify the Sun as the most important source of heat which warms the Earth. CCSS/CE(s): E.ES.01.11; Students should be able to identify the Sun’s warming of land, air, and water. They should make connections between the Sun’s warming and its effect on weather conditions. 6. TLW investigate how plants need sunlight and warmth to grow. CCSS/CE(s): E.ES.01.12; Also, make connections to Kindergarten Science Academic Standard: Life Science - Living, Non-Living, Basic Needs, identifying the basic requirements for life, and demonstrating the importance of sunlight and warmth in plant growth. The Earth is warmer in the daytime than at night, and warmer in the summer than the winter. The Earth is just the right distance from the Sun. Ask the question, What would happen is we had no Sun?
