This Grade 5 science worksheet pairs a short reading passage about the history of star observation with comprehension questions. Students learn how ancient farmers and sailors used the stars, how Galileo used an early telescope to see Jupiter's moons, and how modern space telescopes extend that work. Multiple choice and fill-in items, aligned with NGSS 5-ESS1, build close-reading and analysis skills for curious Grade 5 astronomers.
Style:
Stars and Brightness
Part A: Multiple Choice
Circle the best answer for each question.
1. According to the passage, why did ancient people first track the positions of stars?
A) To predict seasons, plant crops, and navigate at sea
B) To measure the exact mass of distant galaxies
C) To send radio signals to nearby planets in orbit
D) To calculate the energy released by supernova explosions
2. What new tool did Galileo use in the early 1600s to study the night sky?
A) A modern radio dish
B) An early refracting telescope
C) A space-based infrared camera
D) A computer-controlled mirror array
3. Which discovery from Galileo's observations changed views of the solar system most?
A) The Sun is exactly the size of Earth
B) Stars are smaller than nearby planets
C) Jupiter has its own orbiting moons
D) The Moon emits its own bright light
4. How do modern astronomers extend what Galileo started?
A) By staring at the Sun without protective filters
B) By guessing star distances from feelings rather than data
C) By giving up telescopes for unaided eye observations
D) By using space telescopes that detect many wavelengths of light
Part B: Fill in the Blank
Write the correct answer on each line.
1. Ancient astronomers used star patterns to mark the changing seasons of the year.
2. Galileo used a telescope to look more closely at the Moon, Jupiter, and the Milky Way.
3. When Galileo saw four points of light circling Jupiter, he realized they were Jupiter's moons.
4. Modern astronomers place some telescopes in space to avoid blur from Earth's atmosphere.
5. Studying the sky over time helps scientists understand how stars are born and how they change.
