The motion of a Foucault s pendulum and the Coriolis effect are the result of a planet s rotation. Essential Questions: How do the Earth and space affect one another? How has people s understanding of Earth changed over time? Why does gravitational force change? Tides are caused by gravitational interactions between the sun, Earth, and moon. The moon appears to change shape on a monthly cycle. Eclipses occur as a result of positions of Earth, moon, and sun. The altitude of Polaris varies with latitude in the northern hemisphere. Polaris is the axis of star rotation and is located at approximately 0 azimuth. Gravity varies according to the masses of, and distance between, two objects. Analyze a graph of tides. Apply the concepts to various models (i.e. winds, pendulum diagram, ocean currents). Use the ESRT to do above. Identify phases of the moon based on diagrams. Identify locations of moon phases in an Earthmoon system diagram. Identify solar and lunar eclipses in Earth-moon-sun diagrams. Determine latitude of an observer from altitude of Polaris and vice versa. Determine motion of a star toward or away from an observer based on changing wave-length of light (Doppler effect).

Topic: Earth in Space, con t. Standards 1, 2, 4, 7 1.2a, b, c, d Solar Systems Geology Enduring Understanding: Internal and external forces shape the Earth and other planets. Essential Questions: How and why do planets vary from one another? How do events that occur within the solar system impact the Earth? Our solar system formed about five billion years ago from a giant cloud of gas and debris. Gravity caused Earth and the other planets to become layered according to density differences in their materials. Composition of planets varies according to distance from the sun. The characteristics of the planets of the solar system are affected by each planet s location in relationship to the sun. The terrestrial planets are small, rocky, and dense. The Jovian planets are large, gaseous, and of low density. Asteroids, comets, and meteors are components of our solar system. Impact events have been correlated with mass extinction and global climatic change. Impact craters can be identified in Earth s crust. Identify planets by composition Apply data from ESRT.

Essential Question: Why are minerals so crucial to our world? A mineral is a naturally occurring solic with definite chemical composition and crystalline structure. Minerals have physical properties determined by their chemical composition and crystal structure. Minerals can be identified by well-defined physical and chemical properties, such as cleavage, fracture, color, density, hardness, streak, luster, crystal shape, and reaction with acid. Chemical composition and physical properties determine how minerals are used by humans. Minerals are formed as a result of specific environmental conditions. Distinguish between mineral and non-mineral. Compare/contrast between a mineral and nonmineral. Identify how minerals are used by humans. Define conditions that result in mineral formation.

Weather is effected by climate. Exposure to the atmosphere and hydrosphere involves both the physical and chemical breakdown of material. Soil is a by-product of weathering and biological activity. The end result of weathering is the dissolution of the materials that form rock into ionic solution. Transportation of rock material is the result of: -Gravity -Water erosion -Wind and ice erosion -Running water -Man s activities Deposition of particles in a medium is affected by size, shape, density, and velocity. Analyze and measure Earth s materials to obtain: - -Evidence of weathering - Evidence of erosion Draw inferences from observations about the factors that effect erosion.

Topic: Energy 2.1a, k 2.2a, b, d St. 7 Key Ideas: 1, 2 Energy Sources Heat Transfer Insolation Enduring Understanding: Energy is converted into various forms which impact the Earth. Essential Questions: Changes affect the Earth. What causes energy? There are two main sources of energy: External (sun) Internal Energy is transferred by three mechanisms: Radiation Conduction Convection Energy transfer is from source to sink. Nearly all energy is supplied by the sun. Insulation heats Earth s surface and atmosphere unevenly. Predict the type of energy transfer from different energy sources. Use the appropriate ESRT charts. Describe the 3 forms of heat transfer. Distinguish between different sources of energy. Identify and describe ways that energy is transferred.

Topic: Weather St. 1 St. 2 Key Ideas: 1, 2, 3 Key Idea: 2 2.1c, d, e, f, g, h St. 6 Key Ideas: 1, 5, 6 Atmospheric Properties Weather Variables Enduring Understanding: There are many forces that shape the Earth s weather. Essential Question: How do atmospheric properties affect weather? Essential Question: What causes weather and wind patterns? Atmospheric properties vary between atmospheric layers. Weather occurs in the troposphere. The ozone layer absorbs ultra violet rays, which protects Earth. Weather is a result of interaction of temperature, air pressure, and moisture in the air. Winds are a result of differences in air pressure. The magnitude of energy changes is proportional to the energy released. Air temperature changes adiabatically as the air rises and sinks. Interpret the layers of atmospheric charts on the ESRT. Identify the location of stratosphere given appropriate information. Determine wind direction based on temperature and/or air pressure differences. Read and interpret lapse rate chart. Read and interpret the barometric pressure and temperature charts. Describe relationships between temperature, pressure, humidity, dew point and precipitation. Use DP and RH charts.

St. 1 St. 2 Key Ideas: 1, 2, 3 Key Idea: 2 2.1c, d, e, f, g, h St. 6 Key Idea: 1, 5, 6 Air Masses/Fronts Weather Forecasting Enduring Understanding: There are many forces that shape the Earth s weather. Essential Question: How does temperature and pressure determine air flow? Essential Question: How do events in one geographical area affect another? Distribution of land and oceans modifies the wind. Air masses gain the properties of their source region. A front is the boundary between two air masses. The type of front is determined by the relative locations of air masses. The greater the differences between two air masses at front, the greater the severity of weather changes. Describe properties and name air masses by source region. Diagram fronts and label associated air masses. Describe typical weather changes at frontal boundaries. Use ESRT (synoptic data) to draw station models and interpret information from weather maps. Construct and read isolines. Use weather map data, to draw locations of fronts. See next page. Changing weather variables (including the jet stream) can be used to forecast weather. Accurate weather forecasting can minimize property damage and loss of life. Compare and contrast hurricanes (storm surge) and tornadoes. Discuss appropriate safety precautions for various weather phenomena. 12
