A student observed that the appearance of the constellations in the night sky changed over a year. Circle one word or phrase in each set of options to best explain the reason for the change observed by the student.
The constellations appear to change ( size / location / brightness / stars ) throughout the year because Earth ( rotates on an axis / changes distances from the stars / revolves around the Sun / changes seasonal weather ) over time.
Location
Revolves around the Sun

In the winter night sky above Mississippi, the constellation Orion, the hunter, can be observed. The three stars of Orion’s belt are easy to identify. Orion can be seen until May in Mississippi. Which statement best explains why Orion cannot be seen during the summer in Mississippi?
A. The orbit of Earth on its axis shifts Orion to the daytime sky.
B. The rotation of Earth on its axis shifts Orion to the daytime sky.

Locating the North Star has helped people determine direction throughout history. Its northern position in the sky stays the same. Sailors used it to help navigate their ships across open water. Later, people began to use compasses for navigating ships. A student claims that using a compass results in better navigation than locating the North Star. Which statement provides the best evidence to support the student’s claim?
A. A compass needle moves as the user changes direction.
B. A compass can be used to find direction during the daytime.
C. A compass needle must be made of a magnetic iron material.
D. A compass allows the user to find directions other than north.
B. A compass can be used to find direction during the daytime.

The Southern Hemisphere is experiencing summer.
The Southern Hemisphere is tilted ( toward / away from ) the Sun, and the Sun appears ( higher / lower ) in the sky in the Southern Hemisphere. This causes temperatures to be ( cooler / warmer ) than in the Northern Hemisphere. The hours of day time hours are (longer/shorter) during this time.
