This Grade 5 medium worksheet compares stars by size, color, and distance. Students complete nine fill-in sentences and a four-pair matching activity covering apparent brightness, actual brightness, blue and red star colors, and constellations. The challenges build careful reading and help young learners reason about why some stars look brighter from Earth even when other stars truly produce more light.
Style:
Stars and Brightness
Part A: Fill in the Blank
Write the missing word or number on each line.
1. How bright a star looks from Earth is called its apparent brightness.
2. A star can look brighter because it is closer or because it is bigger.
3. The hottest stars usually glow with a blue color.
4. Our Sun is a medium-temperature star that glows yellow.
5. The coolest visible stars look red in color.
6. A pattern of stars that forms a picture in the sky is called a constellation.
7. Two stars can give off the same light, but the farther one looks dimmer from Earth.
8. The actual amount of light a star produces is its actual brightness.
9. Stars appear to move across the night sky because Earth rotates.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
