Standards
• The solar system consists of planets and other bodies that orbit the Sun in predictable paths. As a basis for understanding this concept:
• 1.Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
• 2.Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.
• 3.Students know the path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.

Topic 1
• The solar system consists of planets and other bodies that orbit the Sun in predictable paths. As a basis for understanding this concept:
The Beginnings

Up, Duh!• The Church Approves
!!!
The Ideas, Oh How They Change

Not Happy
Modern Thinking
• Galileo Galilei• A New Invention, The
Telescope!!• Newton and His Laws• The Hubble
Telescope
Topic 2
• Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
Basic Facts About the Sun
• Our Sun is actually… well, average
• The sun is the largest object in our solar system
• It contains approximately 98% of the total solar system mass
What is the Sun Made of?
• Materials we find here on Earth
• These materials are called elements
The Hydrogen and Helium of the Sun
• hydrogen & helium make up 99.9% of the sun’s elements.
• Wow! There is a lot of conversion going on up there.
Topic 3
• 2.Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.
Our Galaxy
• The Big Bang Theory• Spinning and Heating• Shrinking and Heating• A Star is Born
Our Solar System
• Terrestrial Planets• Gas Giants• Pluto & Eris• Satellites
The Smaller Objects
• The Asteroid Belt• The Kuiper Belt• Comets
Topic 4
• 3.Students know the path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.Hey Earth,
How You Doin’?
Lookin’ Good Sun!
Gravity
• Objects don’t change direction unless…
• A Force of Attraction• Mass… Whatd Ya
Call My Momma?
Darn, I hate gravity!!
An Easy Explanation
• Ball and String Demo• Hand = Sun• Ball = Earth• String = You Guessed
it, Gravity
Common Misconceptions
• That’s an Orbit!• The Fall of the Space
Shuttle• So, Do Astronauts
really float?
Man, that’s a long ways
to fall!!!
