Two explorers are lost in the wilderness. They know there is a town to the north. They have a map and are able to determine which way is north while standing next to a small lake. However, they must leave the lake and walk through the forest to get to the town. Once they are in the forest, they will not be able to tell where they are. They decide that they must follow a star in the north. Each person chooses a bright star in the northern direction. They follow their own stars all night, but end up in different locations. One reaches the town, while the other is still lost. Which star do you suspect the explorer who found the town was following? Explain.

• The one that followed Polaris, the north star because it does not appear to move and is always north.

• The one that followed Betelgeuse because it is in Orion and can always be seen throughout the year.

• The one that followed Rigel because it is in Orion and does not appear to move.

• The one that followed the moon.

Markius observes the constellation Orion. He first observes it at 8 P.M. and then later at 12 A.M. He notices that it is in a different place in the sky after four hours. What claim and evidence explain why Orion appears to be in different places in the sky at different times?

• Earth’s orbit around the sun causes Orion to disappear over the horizon

• Earth’s orbit toward Orion causes the constellation to appear to change size.

• Earth’s rotation moves Orion vertically so that its location in the sky changes.

• Earth’s rotation causes Orion’s stars to move in an arc, tilting the constellation.

While looking for a picture of Polaris, Levi comes across this photo. The picture is a form of photography called long-exposure. He wonders why some stars appear as curved streaks while others appear to remain in place. Which of the following explains the phenomena shown in the photo?

• The photographer took a long-exposure photo that shows how the position of stars change as seasons change.

• The photographer took a long-exposure photo that shows how stars rotate around Earth over the course of a month.

• The photographer took a long-exposure photo that shows how stars apparently curve in an arc as Earth rotates over 24 hours.

• The photographer took a long-exposure photo that shows how stars appear to move as Earth revolves around the sun over 24 hours.

Chaly keeps a map of the night sky on her bedroom wall. She identifies Orion on her map. However, when she looks outside, she cannot find the constellation anywhere. What claim and evidence explain why Charly cannot locate Orion?

• Charly cannot locate Orion because it is likely too early in the evening, when Orion is not visible.

• Charly cannot locate Orion because it is likely the summer months, when Orion is not visible.

• Charly cannot locate Orion because it is likely too late in the evening, when Orion is not visible.

• Charly cannot locate Orion because it is located in the Southern Hemisphere and Charly is in the Northern Hemisphere.
