Heather watches the shadow of a tree in her garden. She finds that the length of the shadow varies throughout the day. Heather makes some observations.

Which statement represents a correct observation?

• The shadow at 10 a.m. is shorter than the shadow at 11 a.m.

• The shadow at 12 p.m. is longer than the shadow at 10 a.m.

• The shadow at 5 p.m. is shorter than the shadow at 11 a.m.

• The shadow at 3 p.m. is longer than the shadow at 12 p.m.

Samantha lives in Charleston, South Carolina. She looks outside, and the sky looks sunny and bright. She speaks with her friend Kurt in Rome, Italy, and he tells her that he sees a beautiful full Moon in the night sky.

What statement explains the difference in conditions in these two locations?

• The Earth is round and does not move, which means that Charleston and Rome cannot both have day or night at the same time.

• Charleston and Rome are on different continents, and they cannot both have day or night at the same time.

• Earth spins on an axis, which creates different lengths of day and night in different places on Earth’s surface.

• The Earth rotates, which means the side of Earth facing the Sun has day, while the side facing away from the Sun has night.

Adam observed that the shadow of his basketball goal changes positions during different times of the day and is sometimes long or short. Adam gathered data on the shadow of his basketball goal and placed the data in a table.

Which claim is best supported by Adam’s data?

• The Sun is larger around 12 p.m., which causes the size and direction of the shadows to change.

• The Sun appears low in the morning and evening and high around mid-day, which causes the shadows to appear long or short and change direction.

• The Sun gets closer to and further from the house during the day, which causes the shadows to grow and change directions.

• The Sun’s shadow on the Earth causes the shadows of the goal to lengthen and shorten as well as change direction.
