   “Orbit diagram, top view, not to scale:” For a class poster, Bo draws Earth's path all the way around the Sun. Which motion takes about one year?

   • Rotation
   • Revolution
   • The Moon's orbit

   Camping at night, Milo sees the stars slowly move across the sky, just as the Sun does by day. Why do they seem to move?

   • The stars and the Sun circle around Earth
   • Earth goes around the Sun each night
   • Earth spins, so the whole sky seems to turn
   • The stars drift because Earth is tilted
6. 6.

   “Orbit diagram, top view from above the North Pole, not to scale:” Noah looks at Earth at place P on the orbit diagram. The North Pole leans toward the Sun. Which season is it in the Northern Hemisphere?

   • Summer, because the north leans toward the Sun
   • Winter, because the axis tips away in winter
   • Summer, because Earth is closest to the Sun here
   • Summer in both hemispheres at once

7. Read this first

   Use this

   Orbit diagram, top view from above the North Pole, not to scale: the Sun in the center; Earth at four places lettered P (left), Q (bottom), R (right) and S (top), counterclockwise; at every place the axis is drawn the same way, with the North Pole leaning toward the right of the page. Place R is circled.

8. 7.

   Pia finds Earth at place R, where the North Pole leans away from the Sun. Which season is it in the Northern Hemisphere?

   • Summer, because the axis has turned toward the Sun
   • Winter in both hemispheres at once
   • Winter, because the north leans away from the Sun
   • Winter, because Earth is farthest from the Sun here
9. 8.
