Planetary Systems Unit Part 3: The Solar System Objects in our Solar System orbit the Sun, have distinctive physical characteristics, and move in orderly and predictable motions. Key Learning: How do the objects in our Solar System interact with each other? Unit Essential Question: Concept: The Earth Moon and Sun System Planetary Systems Unit Part 3: The Solar 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? You will be able to answer these questions by the end of Part 2 Vocabulary: Galactic Address Gravity factor Weight Habitable You should already know what these words mean. You will be able to use them in your responses and discussions throughout the unit Planetary Systems Unit Part 3: The Solar System Homework Assignment #6 In the Planetary Systems Readings and Assignments… Read pages 12 and do the assignment on page 12 Planetary Systems Unit Part 3: The Solar System Warm Up #1: If you were a bird flying over Talley Middle School, what would it look like when you looked down? Draw what you would see… Planetary Systems Unit Part 3: The Solar System Galactic Address Planetary Systems Unit Part 3: The Solar System Powers of 10 Planetary Systems Unit Part 3: The Solar System Complete Summary #1: Here are three lists of astronomical objects. Choose the list that shows the objects nearest to Earth first and the objects furthest from Earth last. a. Stars, the dwarf planet Pluto, galaxies b. Stars, galaxies, the dwarf planet Pluto c. The dwarf planet Pluto, stars, galaxies Suppose you were to look at the solar system from a location well outside the orbit of Pluto. Most of what you would see in your picture would be… a. The planet Jupiter b. The planet Saturn c. Comets d. Empty space Planetary Systems Unit Part 3: The Solar System Homework Assignment #7 In the Planetary Systems Readings and Assignments… Read pages 13 and do the assignment on page 13 Planetary Systems Unit Part 3: The Solar System Warm Up #2: Suppose you were standing on the surface of Venus and could see through its thick clouds….. A. How would the Earth look? a. a disk with visible features (clouds and continents) b. a disk that the eye could make out, but too small to see visible features like clouds and continents c. pale blue dot B. What would be the configuration of the Earth and Moon? a. right next to each other in the sky b. far apart from each other in the sky Planetary Systems Unit Part 3: The Solar System Planet Walk Planetary Systems Unit Part 3: The Solar System Complete Summary #2: If it takes you one minute to walk 100 meters, how long would it take you to walk from Earth to Mars? Planetary Systems Unit Part 3: The Solar System Homework Assignment #8 In the Planetary Systems Readings and Assignments… Read pages 14-15 and do the assignment on page 15 Planetary Systems Unit Part 3: The Solar System Life In Space Planetary Systems Unit Part 3: The Solar System Warm Up #3: What planet are you most interested in learning about and why? 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.
