This WebQuest addresses the following Utah State Core standards:

STANDARD I:  Students will understand that the appearance of the Moon changes in a predictable cycle as it orbits Earth and as Earth rotates on its axis.

Objective 1:  Explain patterns of changes in the appearance of the Moon as it orbits Earth.

a. Describe changes in the appearance of the Moon during a month
b. Identify the pattern of change in the Moon’s appearance.
c. Use observable evidence to explain the movement of the Moon around Earth in relationship to Earth turning on its axis and the position of the Moon changing in the sky.
d. Design an investigation, construct a chart, and collect data depicting the phases of the Moon.

Objective 2:  Demonstrate how the relative positions of Earth, the Moon, and the Sun create the appearance of the Moon’s phases.

a. Identify the difference between the motion of an object rotating on its axis and an object revolving in orbit.
b. Compare how objects in the sky (the Moon, planets, stars) change in relative position over the course of the day or night.
c. Model the movement and relative positions of Earth, the Moon, and the Sun.
