How should the students model the tilt of Earth's axis?

• The model Earth could raise up both arms and spin.

• The model Earth could raise one arm and lean forward.

• The model Earth could stretch both arms out to the sides and lean back.

• The model Earth and model Sun could hold hands and circle one another.

Which statement correctly describes how Earth, the Sun and the Moon are positioned when Earth’s oceans experience spring tides?

• Earth, the Moon, and the Sun are in a straight line.

• The Moon, Earth, and the Sun form a right angle.

• Earth, the Moon, and the Sun are not in a straight line or a right angle.

The figure choices show the three possible arrangements of the Sun, the moon, and Earth that result in Earth's high ocean tides. Match each figure with the correct type of tide that will occur.

• middle

• spring tide

• top

• daily high tide

• bottom

• neap tide

A student is modeling interactions between Earth and the Sun. The student places a wooden skewer through a foam ball. The student holds the stick so that it is tilted toward a lamp, as shown below, then moves the ball around the lamp. What is the student modeling?

• eclipses

• moon phases

• rotation

• seasons

A student is modeling the June solstice and the December solstice in the Northern Hemisphere. How will the models of the two solstices differ?

• The north end of Earth's axis will point toward the Sun on the June solstice and away from the Sun on the December solstice.

• The north end of Earth's axis will point toward the Sun on the December solstice and away from the Sun on the June solstice.

• The north end of Earth's axis will lean away from Earth's orbit on the June solstice and lean along Earth's orbit on the December solstice.

• The north end of Earth's axis will lean along Earth's orbit on the June solstice and lean away from Earth's orbit on the December solstice.

The figure shows the moon's position around Earth at various times of the month. What pattern can you determine as the Moon orbits Earth?

• As the moon phases changes from a new moon to a full moon, the tides change from spring tide to neap to spring tide.

• As the moon phases changes from a new moon to a full moon, the tides change from neap tide to spring tide to neap tide.

• As the moon phases changes from a first quarter moon to a third quarter moon, there are no spring tides.

• As the moon phases changes from a first quarter moon to a third quarter moon, there are only spring tides.
