1. April 7 th and 8th Unit 8: Space Science Open-Minded Objective(s): 1.SWBAT identify Sun as the center of our solar system and diagram the location of the eight planets. 2.SWBAT compare and contrast properties of terrestrial planets and gas giants. Relevance: While we know much about the solar system, there is still a lot of unknown aspects for scientists and we must keep an open-mind when researching and learning about those unknowns.

4. The Sun The Sun is the center of our Solar System. Eight planets circle the Sun – called an orbit.

5. Eight Planets In order from closest to the Sun to furthest from the Sun, the planets are… Mercury Jupiter SaturnUranus Neptune Mars Earth Venus

6. Eight Planets Remember the order with this phrase… My Very Educated Mother Just Served Us Nachos

7. What are the names of the eight planets scientists recognize orbiting the Sun? Turn and Talk

8. Rotation vs. Revolution The rotation of a planet is how long it takes the planet to spin around once. The revolution of a planet is how long it takes the planet to orbit the Sun one time. For Earth, it takes 24 hours to rotate once – one day. And 365 days to orbit the Sun – one year.

9. What is the difference between a planet’s rotation and the planet’s revolution? Stop and Jot

11. Solar System The Solar System is divided into two main parts – the inner planets and the outer planets. The inner planets are called the terrestrial planets. The outer planets are called the gas giants.

12. Inner Planets Closer to the Sun Much smaller than the outer planets. Primarily made of solid rock materials.

13. Outer Planets Further from the Sun Much larger than the inner planets. Primarily made of liquid and gases.

14. Astronomical Unit Distances in space are so far that scientists have created their own unit when measuring very far distances in space. One astronomical unit (AU) is the average distance between the Earth and the Sun – about 149,600,000 km.

15. Mercury The closest planet to the Sun. 0.39 AU away from the Sun. 4,879 km in Diameter 173-427°C Period of Rotation – 59 Days Period of Revolution – 88 Days

16. Venus The most similar planet to Earth. 0.72 AU away from the Sun. 12,104 km in Diameter 460°C Period of Rotation – 244 days Period of Revolution – 225 days

17. Earth 1.00 AU away from the Sun. Diameter of 12,756 km -13-37°C Period of Rotation – 24 hours Period of Revolution – 365 days

18. Mars “The Red Planet” 1.52 AU away from the Sun. 6,794 km in Diameter -123-37°C Period of Rotation – 24.6 hours Period of Revolution – 1 year 322 days
