Science Retake Lesson 1

1. Carrie was explaining to a friend how Earth is constantly rotating around its axis as it travels through space. Which of the following would be a good model to demonstrate Earth’s rotation around its axis? *

• A boomerang traveling out and back

• A race car driving around an oval track

• A yo-yo traveling down and back up its string

• A bicycle wheel rotating around the axle

2. A photographer took a long-exposure photo of the stars one night and noticed something strange. Some stars appeared as curved streaks while others didn’t move much. Which explanation explains what the photographer?

• The stars’ movements are due to Earth’s rotation and the moving stars are circumpolar stars.

• The stars’ movements are due to Earth’s rotation and the fixed stars are circumpolar stars.

• The stars’ movements are due to Earth’s tilted axis and the fixed stars are seasonal constellations.

• The stars’ movements are due to Earth’s revolution around the sun and the fixed stars are seasonal constellations.

3. Looking out your window at night throughout the course of a year you notice that different constellations are visible in the night sky. Which statement describes what causes the change in the visible constellations in the sky? *

• Earth’s revolution around the sun results in the side of Earth facing away from the sun facing a different direction in space.

• Earth’s rotation around its axis results in different constellations and changes throughout the year.

• Earth’s movement around its axis results in different constellations being visible in the night sky.

• Earth’s movement up and down its orbital plane results in different constellations being visible in the night sky throughout the year.

4. You are looking at webcams around the world. In half of the cameras it is daytime and in the other half it is nighttime. Given the sun’s stationary position in space, which of the following statements explains why you are observing daytime while the other half of Earth experiences night? *

• Earth’s revolution around the sun.

• Earth’s rotation around its axis every day.

• Earth’s fixed position on its orbital plane.

• Earth’s movement on its orbital plane results.

5. Some mobile device apps allow you to identify and track both celestial objects and human-made objects in the night sky. Which object would NOT show the same pattern of motion due to Earth’s rotation? *

• International Space Station

• planet

• airplane

• weather satellite

6. Dion is shown in the illustration below standing on the pitcher’s mound. He has noticed that he can only see the star constellation Orion on winter nights and the constellation Scorpius on summer nights. They rise and set as they travel across the night sky. Which of the following statements describes how Earth’s orbital plane affects his view of seasonal stars? *

• They are visible when they move towards the sun.

• They are visible when they are above Earth’s orbital plane.

• They are visible when they move away from the sun.

• They are visible when they are below Earth’s orbital plane.

7.) Investigation A Some middle school students were interested in learning more about constellations and their visibility throughout the year. They designed an investigation to track the five different constellations and record the months they were visible in the Northern hemisphere night sky. Their goal was to gather enough data to analyze and find any patterns in their appearance. Their results are shown in the table below. 7. Which constellations would be visible during the winter months based upon the evidence in the table? *

• Constellations 1, 3 and 4

• Constellations 1, 3 and 5

• Constellations 3, 4 and 5

• Constellations 2, 4 and 5

Their goal was to gather enough data to analyze and find any patterns in their appearance. Their results are shown in the table below. 9. Using the evidence collected by the student’s observations of the constellations, predictions can be made about the constellations' height in the sky. During the month of August which constellations would be visible higher in the sky than constellation 2? *

0/1

• Constellations 1 and 5

• Constellations 1, 4 and 5

• Constellations 3 and 4

• Constellations 3, 4 and 5
