Weather Inv. Weather and Ecosystems x Today’s Training • Introduction • Unifying Themes in 5th Grade Science - Tracks Investigating Human Systems - Tracks Investigating Weather Systems - STC Ecosystems - STC Motion & Design • Wrap Up Investigating Weather Systems NC Essential Standards 5.E.1 Understand weather patterns and phenomena, making connections to the weather in a particular place and time. 5.P.2 Understand the interactions of matter and energy and the changes that occur. 5.P.3 Explain how the properties of some materials change as a result of heating and cooling. Clarifying Objectives 5.E.1.1 Compare daily and seasonal changes in weather conditions (including wind speed and direction, precipitation, and temperature) and patterns. 5.E.1.2 Predict upcoming weather events from weather data collected through observation and measurements. 5.E.1.3 Explain how global patterns such as the jet stream and water currents influence local weather in measurable terms such as temperature, wind direction and speed, and precipitation. Clarifying Objectives 5.P.2.1 Explain how the Sun’s energy impacts the processes of the water cycle (including evaporation, transpiration, condensation, precipitation, and run off). 5.P.3.1 Explain the effects of the transfer of heat (either by direct contact or at a distance) that occurs between objects at different temperatures (conduction, convection, or radiation). Formative Assessment Probe • Rainfall Student Misconceptions • Children aged 11-13 understood that air exists in open containers and many believe that air can get into and out of containers. However, children were less sure that air can be contained inside a sealed object. • Some children (aged 11-13) associated the existence of air only with the sensation felt when it moved. • Students also said that clouds are made of cotton, wool or smoke. Making Sense of Secondary Science Driver, Squires, Rushworth, and Wood-Robinson Vertical Alignment • In Kindergarten, students make observations of daily weather to build an understanding of changes and observable weather patterns. • In 2nd, students summarize weather conditions using quantitative measures to describe temperature, wind direction, wind speed and precipitation. They also conduct investigations to build an understanding of basic properties of air (a mixture of gases). Essential Question for the Unit • How can technology be used to build an understanding of weather and climate? Introduction • • • • • • Angle of the Sun’s rays and the tilt of the Earth Proximity to water, winds, and elevation The Sun drives the weather Unequal heating of the Earth Evaporation and condensation Temperature affects air movement Lesson 1: Vacation Destination • Predict then verify temperature • Set up data collection table - Local Weather - Global Weather • Weather Station vs. Technology Weather Station Lesson 2: Why Do Different Places in the World Have Different Weather? • Latitude - equator - hemisphere • Angle of the Sun’s rays - Direct sunlight - Indirect sunlight - Earth’s angle of incidence 23.5° Exploration • • • • • • Flashlight Tray Graph paper Ruler Scissors Globe as model Think About… • How does the pattern of light change when the tray changes from one position another? • What did you notice about the brightness of the light? • Which image was larger, direct or indirect light? Claims and Evidence • I know (claim/new learning) because (data/evidence). Claim Evidence The equator receives direct sunlight. The graph paper had a smaller circle when the flashlight was shined directly on the tray with the graph paper. Areas away from the equator receive less intense solar energy. The light was more spread out when the tray was held at an angle. Lesson 3: Seasons • • • • • The Long Lift Ride Denver, CO vs. Sydney, Australia Northern Hemisphere vs. Southern Hemisphere Opposite Seasons due to Earth’s tilt Model, Model, Model! Lesson 4: American Weather • Proximity to large bodies of water - Generally warmer temperatures in winter - Generally cooler temperatures in summer • Further exploration of uneven heating • Connect to local situations - Wilmington, NC Exploration • Prepare investigation - desk lamp - cup of soil, cup of water - thermometers - timer • Set up data collection table Data Collection Time (minutes) 5:00 10:00 15:00 20:00 Turn off lamp 25:00 30:00 Soil Temperature (°F) Water Temperature (°F) Temperature Graphing Data Minutes Lesson 5: Climb to Cold • Elevation - Snow reflects solar energy back into space. - “Thin air” means less air molecules. - Wind moves heat away from your body. • Connect to local situations - Boone, NC or Ashville, NC Lesson 6: What Drives the Weather? • The Sun is the source of energy for all weather phenomena • Water cycle • Smoke Box to model convection • Connect to uneven heating and cooling of soil and water Weather Wrap Up • Lesson 7 – Investigate Properties of Air – Relate air pressure and winds – Gallon jug demo • Lesson 8 – Weather Patterns/Forecasting – Make 4 separate line graphs and make comparisons • Heat Transfer lessons (supplemental) • Lesson 9 – Assessment Opportunity • Lesson 9-Weather Wise – Travel brochures • Heat Transfer Supplementary lessons – Solar ovens Points to Consider How is NC weather influenced by: • Jet stream? • Gulf Stream?
