3. Hemispheres Hemisphere Four of Them In All! 1. Definition: A hemisphere is a half of a sphere. YOU WRITE: Hemisphere- half a sphere; northern and southern are separated by the equator

4. 2. Northern and Southern Hemispheres NORTHERN HEMISPHERE SOUTHERN HEMISPHERE EQUATOR

5. 3. The Earth’s tilt on its axis and its orbit around the Sun cause the Seasons. YOU WRITE: Seasons- caused by earth tilt and orbit around sun

6. Tilting into the Summer! 4. If the axis is tilted towards the Sun, then it is summer in that part of the world. SUN N S YOU WRITE: Summer- if the axis is pointed towards the sun

7. 5. Quick Question What season is it in the Southern Hemisphere? N S SUN

9. 6. Quick Question What season is it in the Southern Hemisphere? N S SUN

11. 7. The amount of daylight during a day increases as the Earth tilts more towards the Sun.

12. 8. The Earths Tilt Affects Climate The places closer to the Equator do not experience much change in temperature or light through out the year. The places closer to the Equator do not experience much change in temperature or light through out the year. The places closest to the poles experience a dramatic change in temperature and light throughout the year. The places closest to the poles experience a dramatic change in temperature and light throughout the year. YOU WRITE: Places close to equator- not much change in temperature Places close to poles- big change in temperature

13. 9. Guided Practice Name the two hemispheres that effect seasons. Name the two hemispheres that effect seasons. True or false. If it is winter in the northern hemisphere it is also winter in the southern hemisphere. True or false. If it is winter in the northern hemisphere it is also winter in the southern hemisphere. What season is it in the northern hemisphere when this hemisphere tilted towards the sun? What season is it in the northern hemisphere when this hemisphere tilted towards the sun? True or false. The temperature and sunlight changes the most throughout the year in the places closest to the Equator True or false. The temperature and sunlight changes the most throughout the year in the places closest to the Equator

14. 9. Guided Practice If it is summer in Alaska (which is in the northern hemisphere), what season is it in Russia (which is in the northern hemisphere)? If it is summer in Alaska (which is in the northern hemisphere), what season is it in Russia (which is in the northern hemisphere)? If it is summer in Greenland (which is in the northern hemisphere), what reason is it in Australia (which is in the southern hemisphere)? If it is summer in Greenland (which is in the northern hemisphere), what reason is it in Australia (which is in the southern hemisphere)?

15. 10. Independent Practice 1.True or false. It is winter in the southern hemisphere when the southern hemisphere is tilted towards the sun and receiving the most light. 2.Places that are farthest from the equator have harsh winters because A. the earth’s tilt causes them to receive a very small amount of light from the sun during the winter. B the earths tilt causes them to always receive a large amount of light from the sun. C. They are high in elevation. D. all of the above. 3.True or false. The Prime Meridian separates the northern and the southern hemisphere. 4.It is summer in South Africa. What season is it in Europe?

16. 11. Exit Ticket 1.True or false. It is summer in the northern hemisphere when the northern hemisphere is titled towards the sun and receiving the most light. 2.Places that are close to the equator do not have harsh winters because A. the earths tilt causes them to always receive a small amount of light from the sun. B the earths tilt causes them to always receive a large amount of light from the sun. C. They are high in elevation. D. All of the above. 3.What line separates the northern and southern hemisphere? 4.It is winter in Canada. What season is it in Australia?
