This Grade 5 science worksheet leads students through the basic life cycle of stars, from nebula and main sequence to red giant, white dwarf, supernova, and black hole. Fill-in-the-blank items review key vocabulary, while a matching activity pairs telescope types, including Hubble, James Webb, ground-based, and radio dishes, with their uses. Aligned to NGSS 5-ESS1, the sheet helps Grade 5 students compare cosmic scales and tools.
Style:
Stars and Brightness
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Stars first form inside a giant cloud of gas and dust called a nebula.
2. After leaving the nebula, a steady star spends most of its life on the main sequence.
3. When a medium star runs low on hydrogen, it swells into a red giant.
4. After shedding its outer layers, a medium star leaves behind a hot, dense core called a white dwarf.
5. Massive stars end their lives in a powerful explosion called a supernova.
6. The most massive star cores can collapse into objects with such strong gravity that even light cannot escape, called black holes.
7. A huge group of billions of stars held together by gravity is called a galaxy.
8. Light from the Sun reaches Earth in about eight minutes.
9. The closest star beyond the Sun, Proxima Centauri, lies about four light-years away.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
