Students reset three big misconceptions about space science: the Sun is a hydrogen-helium star (not a giant iron planet), Neil Armstrong walked on the Moon during Apollo 11 (not Mars), and telescopes collect light rather than listen for sound. The blanks reinforce that the Sun holds about 99 percent of the solar system's mass and that sunlight reaches Earth in roughly 8 minutes.
Students also identify the Hubble Space Telescope and the International Space Station, then explain why the Sun matters for life on Earth and describe a Voyager-style mission to the outer planets. The result is a working picture of how stars, telescopes, and spacecraft fit together.

Solar System
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The Sun is the largest planet in our solar system and is made of solid iron.
Rewrite: The Sun is a star at the center of our solar system and is made mostly of hydrogen and helium gas.
2. Fix the sentence:
Neil Armstrong was the first person to walk on Mars in 1969.
Rewrite: Neil Armstrong was the first person to walk on the Moon in 1969.
3. Fix the sentence:
A telescope is a tool scientists use to listen to sounds coming from other planets.
Rewrite: A telescope is a tool scientists use to observe distant objects in space by collecting light.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The Sun makes up about 99 percent of the total mass of the solar system.
2. Light from the Sun takes about 8 minutes to reach Earth.
3. The Hubble Space Telescope orbits Earth and takes detailed images of distant galaxies.
4. The International Space Station is a laboratory where astronauts live and work in orbit.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why is the Sun important to life on Earth?
The Sun provides the light and heat energy that Earth needs. Plants use sunlight to make food through photosynthesis, and the Sun's warmth keeps temperatures suitable for living things.
2. Name one spacecraft or mission that explored the outer solar system and describe what it studied.
The Voyager missions traveled past Jupiter, Saturn, Uranus, and Neptune, sending back detailed photographs and data about each planet's atmosphere, rings, and moons.
