1. LOL: Meet Our Solar System LOL: Meet Our Solar System A solar system consists of a star and the objects that travel around it. A solar system consists of a star and the objects that travel around it. Our Solar System includes our central star, the Sun, the planets, moons, asteroids, meteors and comets. Our Solar System includes our central star, the Sun, the planets, moons, asteroids, meteors and comets. The inner planets are Mercury, Venus, Earth and Mars. The inner planets are Mercury, Venus, Earth and Mars. The outer planets are Jupiter, Saturn, Uranus and Neptune. The outer planets are Jupiter, Saturn, Uranus and Neptune. A planet is a large spherical satellite of a star A planet is a large spherical satellite of a star

2. LOL: How Big Are the Planets Most astronomical objects (things in space) are too big and too far away to study up close and in person. We use scale models, smaller versions, to help us understand these objects better. Most astronomical objects (things in space) are too big and too far away to study up close and in person. We use scale models, smaller versions, to help us understand these objects better. The Sun is HUGE compared to all the planets The Sun is HUGE compared to all the planets Outer planets are MUCH larger than inner planets Outer planets are MUCH larger than inner planets Jupiter is the largest planet in our solar system Jupiter is the largest planet in our solar system

4. LOL- Distance of the Planets The inner planets are closer together, and are closer to the sun. The inner planets are closer together, and are closer to the sun. The outer planets are really spread out and much bigger than the inner planets The outer planets are really spread out and much bigger than the inner planets

5. LOL: Earth’s Motion in Space The Earth’s motion (movement) causes us to have day and night. The Earth’s motion (movement) causes us to have day and night. The Earth Rotates every 24 hours and this caused day and night The Earth Rotates every 24 hours and this caused day and night Rotation- is when the Earth is spinning on its axis. Rotation- is when the Earth is spinning on its axis. Axis- is an imaginary line that runs through the 2 poles Axis- is an imaginary line that runs through the 2 poles There is a Tilt in our--  There is a Tilt in our--  Earth’s axis

6. LOL: Earth’s Motion Cont. The Earth rotates counterclockwise The Earth rotates counterclockwise The Earth orbits or Revolves around the sun counterclockwise. The Earth orbits or Revolves around the sun counterclockwise. Revolves (Orbits) – the path an object takes when orbiting around another object Revolves (Orbits) – the path an object takes when orbiting around another object It takes the Earth 365 days to make one complete revolution around the sun. That is a whole year! It takes the Earth 365 days to make one complete revolution around the sun. That is a whole year!

7. LOL: Shadows The sun appears to rise in the East The sun appears to rise in the East The Sun appears to set in the West The Sun appears to set in the West You will have long shadows in the early morning “sunrise” and the evening “sunset” because the sun is low in the sky. You will have long shadows in the early morning “sunrise” and the evening “sunset” because the sun is low in the sky. When the sun is high in the sky you will have shorter shadows When the sun is high in the sky you will have shorter shadows Three things you need to have to make a shadow are: source of light, object, and a surface Three things you need to have to make a shadow are: source of light, object, and a surface

8. LOL: Earth as a Unique Planet We need water, air, the right temperature, food, and shelter to survive. We need water, air, the right temperature, food, and shelter to survive. Earth has all of these! Earth has all of these! We are the only planet that has life on it. We are the only planet that has life on it. The Earth and Sun are alike because the both are in our solar system and the both spin counterclockwise The Earth and Sun are alike because the both are in our solar system and the both spin counterclockwise The Earth and sun are different because the Earth is a planet and the Sun is a star. The sun produces light. The Earth supports life. The Earth and sun are different because the Earth is a planet and the Sun is a star. The sun produces light. The Earth supports life.

9. LOL: Bouncing Light Produce mean to make Produce mean to make  The Sun produces light  The flashlight produces light Our mirrors did not produce light the reflected light Our mirrors did not produce light the reflected light  A mirror is a reflector of light  The moon is a reflector of light

12. LOL: MOON The moon has a pattern of phases that can be recorded and observed The moon has a pattern of phases that can be recorded and observed A Lunar Month is the 29 ½ days it takes the moon to go through all of its phases A Lunar Month is the 29 ½ days it takes the moon to go through all of its phases The moon is made mostly of rock The moon is made mostly of rock We only see one side of the moon because the moon rotates at about the same pace as the Earth. We only see one side of the moon because the moon rotates at about the same pace as the Earth. The moon is Earth’s Satellite The moon is Earth’s Satellite
