Differentiate between states of water and how they relate to the water cycle and weather.

CONTENT a. Demonstrate how water changes states from solid (ice) to liquid (water) to gas (water vapor/steam) and changes from gas to liquid to solid. http://www.eo.ucar.edu/kids/sky/water1.htm b. Identify the temperatures at which water becomes a solid and at which water becomes a gas. c. Investigate how clouds are formed. http://www.srh.noaa.gov/srh/jetstream/synoptic/clouds.htm http://www.eo.ucar.edu/kids/sky/water1.htm (scroll down) Cloud types...http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/clouds/cloud_types.html&edu=elem d. Explain the water cycle (evaporation, condensation, and precipitation). http://www.srh.noaa.gov/srh/jetstream/atmos/hydro.htm http://www.windows.ucar.edu/tour/link=/earth/Water/water_cycle.html&edu=elem http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/home.rxml http://observe.arc.nasa.gov/nasa/earth/hydrocycle/hydro3.html e. Investigate different forms of precipitation and sky conditions. (rain, snow, sleet, hail, clouds, and fog). http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/precipitation.html&edu=elem http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/home.rxml Hail... http://www.srh.noaa.gov/srh/jetstream/tstorms/hail.htm TASKS Research different forms of precipitation and sky conditions to explain rain, snow, sleet, hail, clouds, and fog. http://www.srh.noaa.gov/srh/jetstream/synoptic/precip.htm Demonstrate how water changes states from solid (ice) to liquid (water) to gas (vapor) and changes from gas to liquid to solid. Use a thermometer that can measure temperatures at each of the state changes (below 0° Celsius and above 100° Celsius) and record at what temperature liquid water becomes ice or vapor. Diagram the water cycle depicting different states of matter and temperature changes. Evaporation http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/evap.rxml http://www.srh.noaa.gov/srh/jetstream/atmos/hydro.htm Condensation http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/cond/home.rxml http://www.srh.noaa.gov/srh/jetstream/atmos/hydro.htm Precipitation http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/prcp.rxml http://www.srh.noaa.gov/srh/jetstream/atmos/hydro.htm Investigate how clouds are formed. Keep a record to match the kind of cloud with the weather conditions and predict weather by observing cloud types. http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/home.rxml http://www.srh.noaa.gov/srh/jetstream/synoptic/clouds.htm Write a story about the journey of a drop of water through the water cycle. http://www.srh.noaa.gov/srh/jetstream/atmos/hydro.htm http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/smry.rxml Wet a portion of a sidewalk or chalkboard with a wet paper towel. Observe changes in the surface as it dries. Repeat this and time how long it takes for the water to disappear or evaporate. Then fan the wet area or use a hair dryer to see if the water evaporates at a different rate. http://ga.water.usgs.gov/edu/watercycleevaporation.html http://en.wikipedia.org/wiki/Evaporation Try other areas and conditions to observe the changes in evaporation when the weather is hotter. (The temperature is higher.)

Students will analyze weather charts/maps and collect weather data to predict weather events and infer patterns and seasonal changes.

CONTENT a. Identify weather instruments and explain how each is used in gathering weather data and making forecasts (thermometer, rain gauge, barometer, wind vane, anemometer). http://www.sws.uiuc.edu/atmos/statecli/Instruments/weather_instruments.htm http://app.nea.gov.sg/cms/htdocs/article.asp?pid=1242 b. Using a weather map, identify the fronts, temperature, and precipitation and use the information to interpret the weather conditions. Fronts... http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/frnts/home.rxml http://www.eo.ucar.edu/kids/sky/air5.htm c. Use observations and records of weather conditions to predict weather patterns throughout the year. http://www.research.noaa.gov/k12/html/forecasting2.html d. Differentiate between weather and climate. What is climate? http://www.windows.ucar.edu/tour/link=/earth/climate/cli_define.html&edu=elem TASKS Collect and chart weather data using weather instruments such as thermometer, wind vane, anemometer, barometer, and rain gauge. Compare data seasonally throughout the year to note changes of weather data. For example, you could graph the temperatures for a week in August or September, a week in November or December, a week in February or March, and a week in April or May and compare. http://www.srh.noaa.gov/ffc/html/pastobs.shtml http://weather.uwyo.edu/surface/meteogram/ Use a wind sock, or make a wind speed detector. Tape strips of tissue paper to the end of a pencil. Hold it up to detect wind. A common wind speed instrument used to calculate wind speed is an anemometer. A common wind scale is Beaufort Wind Scale. Wind Speed Anemometer... http://en.wikipedia.org/wiki/Anemometer Beaufort Wind Scale... http://www.spc.noaa.gov/faq/tornado/beaufort.html Record the wind speed and direction for a period of time. Compare your data to the information given by weather forecasters in newspapers, radios, internet, and television reports. http://www.srh.noaa.gov/ffc/html/pastobs.shtml Cut a circle (10 cm diameter) out of paper. Cut the circle into a spiral. Tie a piece of thread to the middle end of the spiral of paper. Hold it over a heat source such as a light bulb. Note the movement. Move the spiral away from the heat source. Note the movement. Relate this movement of heated and cooled air to explain wind patterns. http://www.srh.noaa.gov/srh/jetstream/synoptic/wind.htm Resource information: Beaufort Wind Scale: http://www.stormfax.com/beaufort.htm How to make an anemometer: http://www.energyquest.ca.gov/projects/anemometer.html Observe, record, and interpret weather conditions to predict weather patterns.
