In this lesson, you will be introduced to the Earth’s orbital movement around the Sun, as a means of seeing why the constellations change. In the activity, Universe-in-a-Box, you will make a paper model that can help visualize the Earth’s yearly orbit around the Sun. Use this model to understand why some constellations are only visible during part of the year.

Vocabulary Tip: Rotate vs. Revolve

Two words you will sometimes see to describe the Earth's two movements are "rotate" and "revolve." "Rotate" is the word used to describe Earth's spin around its axis, which it completes once each day. "Revolve" is the word used to describe the Earth's movement in its orbit around the sun, which takes one year to complete.

ROTATE = SPIN
REVOLVE = ORBIT

Both of these words start with the letter "r" and come from Latin, so at first it might be easy to mix them up. But here's a helpful mnemonic device for keeping them straight:

"Rotate has an 'a' like 'axis'."
