This Grade 5 science worksheet sharpens constellation identification by describing connect-the-dots star patterns. Students decide whether clues match Orion, Cassiopeia, the Big Dipper, or Ursa Major, then explain how the Big Dipper points to Polaris. Sentence corrections, fill-in-the-blank items, and short answers reinforce science vocabulary while supporting NGSS 5-ESS1, giving Grade 5 learners practice with reading comprehension and spatial reasoning about familiar northern sky patterns.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A constellation that look like a hunter with a sword is Orion.
Rewrite: A constellation that looks like a hunter with a sword is Orion.

Part B: Fill in the Blank
Write the missing word or number on each line.
1. A pattern of seven dots shaped like a soup ladle in the northern sky is the Big Dipper.
2. Three dots in a straight row across the middle of a hunter shape is Orion's Belt.
3. A zigzag of five dots forming a W or M shape belongs to the constellation Cassiopeia.
4. Connect-the-dots that form a Great Bear with the Big Dipper inside name the constellation Ursa Major.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. How can the Big Dipper help you find Polaris in the night sky?
Follow the line made by the two stars at the end of the Big Dipper's bowl, and it points directly to Polaris.
2. Why might one observer call Cassiopeia a W and another call it an M?
Cassiopeia rotates around Polaris during the night and across seasons, so its zigzag shape sometimes appears upright like a W and sometimes flipped like an M.
