Planetary Systems Unit Part 3: The Solar System Name________________________ Period____ ___/105 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? Concept: Earth in Space Concept: The Earth, Moon.

(1 point) ___________________________________________________________________ ___________________________________________________________________ 2 __/5 Galactic Address We are but a small spot on Earth in an immense solar system, galaxy and universe. We live in the Milky Way Galaxy. Most galaxies belong to groups called clusters of galaxies. The Milky Way Galaxy belongs to a cluster called the local group which contains more than 20 galaxies in a great sphere. The Milky way is located in Virgo supercluster. Superclusters are the largest known formations in the universe and we belong to the Virgo super cluster. Directions: Write your galactic address and be sure to include the following… (10 Points) ADDRESS:_______________________________________________ TOWN: __________________________ COUNTY: _________________________________ STATE: _______________________________ COUNTRY: ____________________________ CONTINENT: _________________________________ HEMISPHERE: ______________________________ PLANET: ____________________ OUR SOLAR SYSTEM GALAXY: _________________ LOCAL GROUP SUPERCLUSTER: ___________ UNIVERSE Analysis Questions (5 points) 1.

(2 points) _________________________________________________________________ _________________________________________________________________ 5 __/10 HOW MUCH YOU WEIGH AT DIFFERENT LOCATIONS? Directions: Read the following statement and complete the chart below. You may use a calculator. (?? Points) 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. Your Weight on Earth (or pick a weight) __________ Gravity Factor at surface Location My weight at this location (where Earth=1) Sun 27.9 Mercury 0.37 Venus 0.88 Earth 1.00 Moon 0.17 Mars 0.38 Jupiter 2.64 Saturn 1.15 Uranus 1.15 Neptune 1.12 Dwarf planet Pluto 0.04 Question: Number your list of locations in order from where you weigh the most to where you weigh the least. After looking at this data, what do you think causes the variation in your weight?

Be sure to follow the procedure all parts of the procedure, check your work, and complete each section thoroughly! (35 points) Problem: How does the Mass of a Planet affect how high you can jump? Manipulated Variable: (1 point)__________________________________ Responding Variable: (1 point)__________________________________ Hypothesis: (1 point) ___________________________________________________________________ ___________________________________________________________________ Materials: Meter Stick Calculator Procedure: 1. Working in groups of three, have one member of the group hold a meter stick vertical to the ground with the zero ends touching the ground. 2. The second group member will observe and record the jump height of group member three. 3. Group member three makes a standing jump next to the meter stick. This height is recorded for three jumps. Average the three jumps together and record the average jump height on Earth. 4. Reverse roles two more times so that each member of the group is able to be the jumper and get their average jump height on Earth. 5. Record your jump heights and average jump heights on the chart below.
