Julie and Kyle are using a model to study the system of Earth and the Sun. The

round light represents the Sun and the ball represents Earth.

How can they model the cycle of day and night on Earth?

• Spin the ball while shining the flashlight on it.

• Move the ball in a circle around the flashlight.

• Move the flashlight in a circle around the ball.

• Turn the flashlight on and off.

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 launches rockets from the airports in Miami and Tampa.

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

• NASA controls space missions from a center in Orlando.

• NASA trains astronauts in many cities across Florida.

The Hubble Telescope and the James Webb Telescope are both powerful tools for

exploring space. They have taken pictures of stars, galaxies, and other huge objects.

How do telescopes, such as the Hubble Telescope and James Webb Telescope, extend

the ability of humans to observe space?

• They allow humans to observe deep space objects not visible from Earth.

• They allow humans to land on other planets to collect data.

• They allow humans to collect samples from deep space.

• They allow humans to send spacecraft outside of the solar system.

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 this apparent motion of the stars?

• the revolution of the stars around Earth.

• the movements of the Sun and Moon through space.

• the rotation of Earth on its axis

• the movement of clouds and other objects close to Earth’s surface
