1 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?

2 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

3 Earth’s Movement Why are there 365 days in a year? Earth has the perfect orbit for humans! Gizmo's Birthday

4 How does the Earth move? Revolution: Earth travels on an orbit around the sun – Takes 365 1/4 th 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? Why do we have 4 seasons?

5 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

6 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

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

8 Tomorrow Hemispheres – North, South Equinox, Solstice terc/content/visualizations/es0408/es0408page0 1.cfm?chapter_no=04 terc/content/visualizations/es0408/es0408page0 1.cfm?chapter_no=04 ons/animations/01_EarthSun_E2.html ons/animations/01_EarthSun_E2.html r/science/space-sci/solar-system/equinoxes- sci.html

9 Bellwork Get out HW from two nights ago to check Standard: also have out your Guided Reading Questions from yesterday

10 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

11 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

12 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 21 st – The closest the Earth’s North Pole points toward sun, most energy on Northern Hemisphere Winter Solstice = December 21 st – The farthest the Earth’s North Pole points toward sun, least energy on Northern Hemisphere

13 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

14 Earth Sun Relationship Simulation

15 Agenda Check HW (3 rd period: chart) Review solstices and equinoxes Foldable HW: Finish Foldable Quiz 1.2 on Friday!

16 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
