• A type of telescope used to observe distant stars

• A large star that provides light to planets

• A rock that moves through space

What is the International Space Station (ISS)?

• A large spacecraft where astronauts live and work in space

• A satellite used to predict weather patterns on Earth

• A rocket that carries supplies to the Moon

• A telescope that orbits around Jupiter

How does a rocket demonstrate Newton's Third Law of Motion?

• A rocket push gas down, and the gas pushes the rocket up.

• A rocket moves forward by pulling on the ground.
• A rocket's fuel burns without any gas being expelled.
• A rocket hovers in place by using magnetic fields.
