• grouping of meteors that orbit the Sun between Earth and Mars.

• grouping of icy particles surrounding the Sun outside the solar system.

• grouping of asteroids that orbit the Sun between Neptune and Uranus.

• grouping of planets near the edge of our solar system.

Charlotte and Liam are working on a science project about the solar system. Which of the following diagrams is the most accurate representation of the locations and movements of Earth, the Sun, and the Moon?

• [Diagram A]

• [Diagram B]

• [Diagram C]

Isla is learning about celestial bodies in her science class. She wonders which celestial body rotates, is made of gas, and provides light and energy?

• Sun

• Asteroid

• Moon

• Meteor

Nora is observing the movement of objects in a large circular ice rink. How do the objects within the ice rink move?

• The objects within the ice rink move around the inner skaters driven by the force of their movements.

• The objects within the ice rink move around a central skater driven by the force of their movements.

• The objects within the ice rink move around the center of the rink driven by the force of gravity.

• The objects within the ice rink move around each skater driven by the force of their movements.

Benjamin and Olivia are discussing celestial bodies in our solar system. Which of the following best describes the locations of asteroids and comets in our solar system?

• Asteroids are mostly located in the asteroid belt, which lies between Mars and Jupiter, and comets can be found past Jupiter in the Kuiper Belt or the Oort cloud.

• Comets are mostly located in the asteroid belt, which lies between Mars and Jupiter, and asteroids can be found past Jupiter in the Kuiper Belt or the Oort cloud.

• Asteroids and comets are found in the asteroid belt.

• Asteroids and comets are found in the Oort cloud.

Elijah and James are discussing the solar system. Which of the following best describes the physical properties, locations, composition, and movement of the planets in our solar system, as well as the force that keeps them moving around the Sun?

• The planets are made of rock or gas, are located at varying distances from the Sun, orbit the Sun in elliptical paths, and are kept in motion by gravity.

• The planets are all made of ice, are located close to the Sun, move in straight lines, and are kept in motion by magnetism.

• The planets are made only of metal, are evenly spaced from the Sun, do not move, and are kept in place by air pressure.

• The planets are made of water, are located outside the solar system, orbit the Sun in circles, and are kept in motion by electricity.
