Presentation on theme: "Bellwork What sea is located at (15N,75W)?"— Presentation transcript:
1Bellwork 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?
2Agenda Bellwork: Reviewing Map Elements Notes: How Earth Moves HW: Graphic OrganizerIf you haven’t made up Quiz 1.1 you need to!Tomorrow: start in class project on Earth’s Movement
3Earth’s Movement Why are there 365 days in a year? Earth has the perfect orbit for humans!Gizmo's Birthday
4How does the Earth move?Revolution: Earth travels on an orbit around the sunTakes 365 1/4th daysEarth revolves around the sun, which causesThe length of our yearOur seasons: as the Earth moves, we get 4 seasonsWhy do we have 4 seasons?
5How does the Earth move?Rotation: The Earth spins on its axis every 24 hoursAxis = invisible line connecting North and South poleEarth’s axis tilts at 23.5 degreesEarth’s rotation causes day and nightEarth turns on its axis
6How does the Earth move?Tilt: Earth’s axis is tilted at a 23.5 degree angleCauses night and day to be longer or shorterCauses the 4 seasons
7Graphic Organizer - Practice NumberWhat is it?What does it do?RotationRevolutionTilt
8Tomorrow Hemispheres – North, South Equinox, Solstice
9Bellwork Get out HW from two nights ago to check Standard: also have out your Guided Reading Questions from yesterday
10Agenda Bellwork: Recap and Catch Up Notes: Earth’s Movements (finish up)FoldableHW: Finish FoldableHonors: Prep for In class project tomorrowGroups of 5, 6 groups2 Rotation, 2 Revolution, 2 Tilt1 Posterboard, markers, paper, etc
11Earth-Sun Relationships Two HemispheresHemi = halfSphere = circleNorthern Hemisphere = above equatorSouthern Hemisphere = below equatorAs Earth revolves, sun’s energy hits each hemisphere differently= opposite seasons
12Earth-Sun Relationships 4 seasons (Winter, Spring, Summer, Fall)As Earth revolves, have different amounts of sun’s energy hitting the areaSummer Solstice = June 21stThe closest the Earth’s North Pole points toward sun, most energy on Northern HemisphereWinter Solstice = December 21stThe farthest the Earth’s North Pole points toward sun, least energy on Northern Hemisphere
13Earth-Sun Relationships Amount of energy received affects temperature and length of dayShortest day on Winter SolsticeLongest day on Summer SolsticeEquinox = equal energy points (2)Vernal Equinox = March 21Autumnal Equinox = Sept 22Equal Day/Night
15Agenda Check HW (3rd period: chart) Review solstices and equinoxes FoldableHW: Finish FoldableQuiz 1.2 on Friday!
16Foldable 1) Fold 4 sheets of paper and staple 2) Give your foldable a title3) Label each tab (Rotation, Revolution, Tilt)4) Inside each tab, explain the movement of the Earth – use vocabularyRotation: axisRevolution: orbitTilt: solstices and equinox5) Draw a picture to explain
