1. Planetary Systems Unit Part 3: The Solar System Key Learning: Objects in our Solar System orbit the Sun, have distinctive physical characteristics, and move in orderly and predictable motions. Unit Essential Question: How do the objects in our Solar System interact with each other?

2. Planetary Systems Unit Part 3: The Solar System Concept: The Earth Moon and Sun System Lesson Essential Questions: 1. How do we write our galactic address? 2. How do scale models help us represent our Solar System? 3. How is life in space different from Earth? 4. Why is Earth the only planet known to contain life in our Solar System? Vocabulary: Galactic Address Gravity factor Weight Habitable You will be able to answer these questions by the end of Part 2 You should already know what these words mean. You will be able to use them in your responses and discussions throughout the unit

14. Planetary Systems Unit Part 3: The Solar System Warm Up #3: What planet are you most interested in learning about and why?

15. Planetary Systems Unit Part 3: The Solar System How Much You Weigh at Different Locations? How much you weigh depends on the force of gravity at your location. The table below shows what the force of gravity would be at different locations in our Solar System based on a value of 1 on the Earth’s surface. For example, if you weighed 100 pounds on Earth, you would weigh 17 pounds on the Moon. 100 pounds (your Earth weight) multiplied by 0.17 (the gravity factor for the moon) = 17 pounds. Remember, your mass does not change at different locations. Your mass remains the same; it is your weight that changes due to the force of gravity on the different planets.
