UT2 Review

Joan models the phases of the Moon by using a golf ball to represent the Moon and a lamp to represent the Sun. She turns off the lights so the lamp is the only light in the room. She holds the golf ball out in front of her and moves the ball around herself. As she looks at the ball, she can see different amounts of light and shadow on the ball, resembling the phases of the Moon as it orbits Earth. Where should she hold the golf ball to see a new moon?

• in front of her as she faces the lamp

  Holding the ball in front of her will not allow her to see any of the light from the lamp that is reflected by the ball because she would be viewing it from the opposite side. This would create the appearance of a new moon.

• on the other side of the lamp from her

  This will allow some of the light from the lamp that is being reflected by the ball to be visible to Jazara.

• in front of her with her back to the lamp

  This will allow some of the light from the lamp that is being reflected by the ball to be visible to Jazara.

• off to her side with the lamp in front of her

  This will allow some of the light from the lamp that is being reflected by the ball to be visible to Jazara.

A student creates a model of a calendar to show the phases of the Moon in January.

What can a student determine by observing the phases of the Moon?

• the compositions of the Sun, Earth, and the Moon

• the tilt of the Moon and Earth in relation to the Sun

• the speed of the revolutions of the Moon and Earth around the Sun

• the positions of the Sun, Earth, and the Moon in relation to each other

A student creates two models to demonstrate phases of the Moon. The models are shown.

Q. Which moon phases can the models be used to demonstrate?

• Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a new moon.

  Model 1 shows Earth between the Moon and the Sun, which allows sunlight to be reflected from the surface of the Moon. Model 2 shows the Moon in between Earth and the Sun, which prevents sunlight from being reflected.

• Model 1 can be used to demonstrate a new moon, and Model 2 can be used to demonstrate a third quarter moon.

  The position of Earth between the Moon and the Sun demonstrates a full moon, not a new moon. A third quarter moon does not appear when Earth, the Moon, and the Sun are in a line. 

• Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a waning crescent moon.

  A waning crescent moon does not appear when Earth, the Moon, and the Sun are in a line. 

• Model 1 can be used to demonstrate a first quarter moon, and Model 2 can be used to demonstrate a waxing gibbous moon.

  A first quarter moon and a waxing gibbous moon do not appear when Earth, the Moon, and the Sun are in a line.

Tin lives in Atlanta and observes the moon as a waxing gibbous. Her cousin lives halfway around the world in China. Do Tin and her cousin see the same phase of the moon at the same time?

• No, because the phase of the Moon changes as the Earth rotates.

• Yes, because the phase of the Moon does not change as the Earth rotates.

• Yes, because the Moon quickly rotates around the Earth and will appear in the same phase to everyone on Earth.

• No, because the Earth quickly rotates around the Moon and will appear in different phases to everyone on Earth.

How could this model be altered to correctly illustrate a lunar eclipse?

• The Moon should be moved to the right of the Earth, directly in line with the Sun’s rays.

  This answer demonstrates an ability to identify how the model should be altered to show the correct alignment of the Sun, Earth, and Moon during a lunar eclipse.

• The Moon should be moved to the left of the Sun, so the Sun is in between the Moon and the Earth.

  This answer demonstrates an understanding that the Sun, Earth, and Moon must be aligned during an eclipse, but the order is not correct.

• The Moon should be moved to the left of the Earth, directly in line with the Sun’s rays.

  This answer demonstrates an understanding that the Sun, Earth, and Moon must be aligned during an eclipse, but the order is not correct.

• The Moon should be left where it is, and the Earth should be moved closer to the Sun.

  This answer demonstrates an understanding that the Sun's rays are related to a lunar eclipse, but does not demonstrate an understanding of blocked rays or Sun, Earth, and Moon position.

In what order are the Moon, Earth, and the Sun aligned during a total eclipse of the Sun?

A.

• in the order of the Sun, the Moon, and Earth in a straight line

• in the order of the Sun, Earth, and the Moon in a straight line

• in the order of Earth, the Sun, and the Moon in a straight line

• in the order of the Moon, Earth, and the Sun in a straight line

Eclipses occur because the Moon

• does not create its own light and only reflects light from the Sun.

• does not create its own light and only reflects the light from Earth.

• creates its own light, which is blocked by the Sun during an eclipse.

• creates its own light, which is blocked by Earth during an eclipse.
