|In third grade, students study about the movements of the moon and
planets around the sun. They learn that the reason that the earth has
seasons is because of the fact that the earth moves in an orbit around
the sun, and it is tilted on its axis. To assist in their understanding
of this fact, they construct animations using Frames by Tech4Learning|

They also study about the movements of the moon. They understand that the moon moves in a circular orbit around the earth, and that the moon appearance is different in the night sky, depending upon the location of the earth, sun, and moon.
