Earth, Moon, and Sun Movements

Throughout the night, many stars APPEAR to move in a circular path across the sky. The center of the circle is Polaris, also called the North Star. What causes the apparent motion of the stars? (Why does it look like the stars are moving)

• the ROTATION of the earth on its AXIS

• the REVOLUTION of the stars around the Earth

• The movement of the Sun and Moon through space

• The movement of clouds and other objects close to Earth's surface

If the face represents someone living in Florida, what will a person observe in step 3?

• the changes to the light and heat released by the model Sun

• the revolution of the model sun around the globe

• the rotation of the model sun around its axis

• the rising and setting of the model sun

Many scientists and engineers work for NASA, the agency of the U.S. Government that explores space. How has NASA contributed to the economy and culture of Florida?

• NASA trains astronauts in many cities across Florida

• NASA controls space missions from a center in Orlando

• NASA launches rockets from the airports in Miami and Tampa

• NASA launches rockets from a space center on the Atlantic Coast of Florida

Jeremiah and Hailey are using a globe and a lamp to model the Earth and the Sun. If they wanted to extend their model to show the changing shapes of the moon, what object should they add to represent the Moon?

• a second lamp placed behind the globe

• a small ball that orbits the globe

• a mirror that reflects light from the lamp

• a sticker placed on the opposite side of the globe

Ariana and Dastan observe the pattern of stars shown here on a clear night. The lines were added after the photo was taken. What changes will occur to the pattern during the night?

• The pattern will break apart as the stars move

• The pattern will change as more stars appear

• The pattern will stay the same, and IT will move

• The pattern will stay the same, but APPEAR to move across the sky.

Athena observes the stars on a clear summer night. Will she observe the saem set of stars on a clear night in winter?

• Yes, because Earth rotates on its axis

• Yes, because Earth is always facing the same direction in space

• No, because Earth revolves around the sun.

• No, because starts only appear in summer

Michael's team is studying the moon. They learn that the moon tonight is in the new moon phase. What phase of the moon should the team expect in about one week (7 days)?

• the same new moon

• a first quarter moon

• a full moon

• a third quarter moon

One night, Madelyn observes the Moon in the shape shown in the photo. When will the moon next appear as this same shape?

• after about 7 days or 1 week

• after about 2 weeks or 14 days

• after about 4 weeks or 28 days

• after about 6 months

Bella and Ty are using a model to study the system of Earth and Sun. The round light represents the sun and the ball represents Earth. How can they model the cycle of day and night on earth?

• Turn the flashlight on and off

• Spin the ball while shining the light on it (rotate)

• Move the ball in a circle around the flashlight (revolve)

• Move the flashlight in a circle around the ball

Zoe and Melanie are discussing the way the sun, earth and the moon move through space. Which of the following best describes earth's movement?

• Earth is stationary, while the sun moves around it

• Earth rotates on its axis and moves around the sun

• Earth rotates on its axis but does NOT move around the sun

• Eath moves around the sun but does NOT rotate on its axis
