Cornell Notes on Week 12/12/11 Mrs. K. Williams Topic: Outer planets and other small objectsVocabulary: Main Idea/Questions: 1. What are the gas planets 2. Why are the gas giants dense inside? 3. Name impt. Facts about each planet. a. Jupiter *(Great Red Spot Planet) b. Saturn*(The planet with rings) c. Uranus (the blue green planet) d. Neptune (farthest planet) 4. What are other objects in space? a. Pluto b.Gas planet moons *Students will create a foldable for their notebook on this. These notes will go on the inside. Outside folds will include names of planets and characteristics/titles of each Pg.94E Gas giant- planets made mainly of hydrogen, helium, and other gases Ring- wide, flat zone of small particles that orbit a planet Notes: 1. Jupiter, Saturn, Uranus, Neptune 2. Gravity pulls the material together and makes the gases very dense. 3. Jupiter- 5 times farther from the sun take less than 10 hrs. to turn once. Takes 12 earth yrs to go once around the sun. Red spot on planet is an active storm lasting atleast 100 yrs. This planet has ammonia ice clouds Saturn has large rings made of water ice, tiny moons. Has lower density than Jupiter, rotates every 11 hours, takes 30 Earth years to go around the Sun. Uranus has methane gas in its atmosphere, takes 84 years to revolve the Sun, spins on one side of its axis; atmosphere made of methane, ammonia, and water Neptune has methane ice crystals in atmosphere; has a storm called the Great Dark Spot; 4. Pluto, asteroids, comets, meteors, meteorites. a. Pluto- smallest of planetary bodies and smaller than Earth’s moon. Has a thin atmosphere. Has its own moon, Charon. Its’orbit changes when compared to other planets. b. Name some moons (p.102E) c. What is an asteroid? (p.103E) d. What do asteroids have craters? (p.103E) e.What is a comet? (p.104E) f. In what part of a comet’s orbit is its tail the longest? (p.104E) g. What are the differences btwn meteors and meteorites? (p.105E) Review questions: 1. How are Pluto and most moons of the gas giant planets similar? 2. What do you think Pluto would look like if its orbit brought it close to the Sun? c. d. e. f g.
