Bellwork • What sea is located at (15N,75W)? • What three countries fall on the 105W line of longitude? • What state is at (45N, 120W)? • What country is Northeast of Canada?
Agenda • Bellwork: Reviewing Map Elements • Notes: How Earth Moves • HW: Graphic Organizer • If you haven’t made up Quiz 1.1 you need to! • Tomorrow: start in class project on Earth’s Movement
Earth’s Movement • Why are there 365 days in a year? • Earth has the perfect orbit for humans! • Gizmo's Birthday
How does the Earth move? • Revolution: Earth travels on an orbit around the sun • Takes 365 1/4th days • Earth revolves around the sun, which causes • The length of our year • Our seasons: as the Earth moves, we get 4 seasons • Why do we have 4 seasons?
How does the Earth move? • Rotation: The Earth spins on its axis every 24 hours • Axis = invisible line connecting North and South pole • Earth’s axis tilts at 23.5 degrees • Earth’s rotation causes day and night • Earth turns on its axis
How does the Earth move? • Tilt: Earth’s axis is tilted at a 23.5 degree angle • Causes night and day to be longer or shorter • Causes the 4 seasons
Tomorrow • Hemispheres – North, South • Equinox, Solstice • http://www.classzone.com/books/earth_science/terc/content/visualizations/es0408/es0408page01.cfm?chapter_no=04 • http://esminfo.prenhall.com/science/geoanimations/animations/01_EarthSun_E2.html • http://video.nationalgeographic.com/video/player/science/space-sci/solar-system/equinoxes-sci.html
Bellwork • Get out HW from two nights ago to check • Standard: also have out your Guided Reading Questions from yesterday
Agenda • Bellwork: Recap and Catch Up • Notes: Earth’s Movements (finish up) • Foldable • HW: Finish Foldable • Honors: Prep for In class project tomorrow • Groups of 5, 6 groups • 2 Rotation, 2 Revolution, 2 Tilt • 1 Posterboard, markers, paper, etc
Earth-Sun Relationships • Two Hemispheres • Hemi = half • Sphere = circle • Northern Hemisphere = above equator • Southern Hemisphere = below equator • As Earth revolves, sun’s energy hits each hemisphere differently • = opposite seasons
Earth-Sun Relationships • 4 seasons (Winter, Spring, Summer, Fall) • As Earth revolves, have different amounts of sun’s energy hitting the area • Summer Solstice = June 21st • The closest the Earth’s North Pole points toward sun, most energy on Northern Hemisphere • Winter Solstice = December 21st • The farthest the Earth’s North Pole points toward sun, least energy on Northern Hemisphere
Earth-Sun Relationships • Amount of energy received affects temperature and length of day • Shortest day on Winter Solstice • Longest day on Summer Solstice • Equinox = equal energy points (2) • Vernal Equinox = March 21 • Autumnal Equinox = Sept 22 • Equal Day/Night
Earth Sun Relationship • Simulation
Agenda • Check HW (3rd period: chart) • Review solstices and equinoxes • Foldable • HW: Finish Foldable • Quiz 1.2 on Friday!
Foldable • 1) Fold 4 sheets of paper and staple • 2) Give your foldable a title • 3) Label each tab (Rotation, Revolution, Tilt) • 4) Inside each tab, explain the movement of the Earth – use vocabulary • Rotation: axis • Revolution: orbit • Tilt: solstices and equinox • 5) Draw a picture to explain
