1 Name: Grade 6 Science Space Unit Test 1. The Earth s axis in tilted 23.5 Section C Short Answer (Use complete sentences, and diagrams to help) 1. Explain the difference between the rotation and revolution. 2. Explain why we experience day and night on Earth. 3. Explain The 2 factors that contribute to the changing of the seasons, and how they work together to create 4 different seasons on Earth. 1. Name one basic need that an astronaut has while in space, and explain how this need is met Astronauts need They meet this need by 4. You have been chosen to lead Manitoba s first ever space mission. Referencing what you ve learned about day to day living in space, identify some differences you will experience between daily routines in space, and daily routines on earth. Section D Diagrams (All diagrams require labels for each and every part) 1. a) Waxing is when the moon appears to get. b) Waning is when the moon appears to get. 2. In the spaces below, draw a picture that represents the type of moon:

2 Gibbous Quarter Full Crescent 3. The moon takes approximately days to orbit the Earth. 1. Shade in each circle to represent all 8 phases of the moon in order. Be sure to label each phase.

3 2. In the space below: a) Draw, label and describe a Lunar Eclipse b) Draw, label and describe a Solar Eclipse 4a) Draw and label a diagram that shows the Earth s position in relation to the Sun when the northern hemisphere is having winter. 4b) In this position, the days in the northern hemisphere are. 4c) In this position, which hemisphere is experiencing direct sun rays? 2. Name the planets, in order from closest to the sun to furthest away. Start with the planet closest to the Sun: a) f) b) g) c) h) d) i) e)

4 I am - Read each clue, then write down the planet that goes with the clue 3. I am the proud owner of a huge Red Spot, which is actually an atmospheric storm traveling 225 mph. I am. 4. I am called the Sideways Planet because my axis is tilted at roughly 90 and my surface frozen methane crystals. I am. 5. I take 88 days to orbit around the sun, and I make one full rotation in 59 days. I can also get as cold as -183 C, and as hot as 407 C. I am. 6. Out of all the planets, my rings are the most noticeable, and I am the second biggest of all nine planets. I am. 7. I have thick, toxic, yellow clouds surrounding me, so I get VERY hot, and I m the only planet that orbits the sun in a clockwise manner. I am. 8. There is no way you could live on me, because I have very little oxygen due to no atmosphere. I am also red because of all the rust on me. I am. 9. Hello, I move very slowly around the sun (165 years for one orbit). Oh yeah, I have the Great Dark Spot, but it vanished in I am. 10. I will take 248 Earth Years to go around the Sun, but I can rotate around my axis in only 6 days and 9 hours. Some people say I m not even a planet just because I m different. I am. more mass on moon or earth, gravity? 11. Explain why people on Earth only see one side of the moon

5 Section A: Vocabulary: Match the vocabulary words in the left column with the definitions on the right 1. lunar eclipse 2. March 21 st waxing 5. Summer Solstice 6. solar eclipse 7. December 21 st 8. Equinox 9. Waning 10. The moon appears to get bigger The official first day of Spring The moon is between the sun and Earth, casting a shadow over the Earth The name for a day when the Earth s axis is tilted neither towards nor away from the sun June 21 st of every year The Earth is between the Sun and moon, blocking the Sun s rays The moon appears to get smaller Winter Solstice Section B: True or False: Place a T or an F in the space provided a) The Earth s axis is tilted at an angle of 23.5 degrees b) North America gets indirect sun rays in August c) Planets and moons are all held in place by gravity d) The moon is the Earth s closest star e) If it is daytime in Europe (north), the south side of Earth will have night f) The tilt of the Earth s axis changes as the Earth revolves around the sun g) Everywhere on Earth has the same number of hours of day and night h) The time it takes for the Sun to orbit around the Earth is 365 ¼ days

6 i) The Earth rotates at a faster speed than it revolves j) We only see one side of the moon because it rotates and revolves at the exact same speed Section C: Multiple Choice Circle only one answer!! k) What is the name of the imaginary line around which the Earth spins? a. Equator b. Axis c. Prime Meridian d. Ellipse l) Which of the following is a method ancient scientists used to determine the Earth is round? a. Observing the shadows of 2 sticks planted in Northern and Southern Egypt b. Taking satellite photos of the Earth c. Watching a ship sail off into the distance d. Looking through a telescope m) What effect does the moon s gravity have on Earth? a. The 4 seasons b. Ocean tides c. A lunar eclipse d. Day and night n) The Earth revolves around the Sun; therefore, it is a of the Sun: a. Revolution b. Gravitational pull c. Natural satellite d. Ellipse
