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
Graphic Organizer - Practice Number What is it? What does it do? Rotation Revolution Tilt
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
