Learning journey

Your child is discovering the wonders of space — learning about stars, planets, and galaxies, understanding how our ideas about the solar system have changed over time, and exploring humanity's journey into space.

Evidence of understanding

  • Describe that stars form from clouds of gas and dust called nebulae
  • State that stars produce energy by fusing hydrogen into helium in their cores
  • Explain that massive stars end in a supernova explosion while smaller stars shrink to become white dwarfs

Assessment prompt

Can Life Cycle of Stars explain that stars are born, live for a very long time, and eventually die — and that really big stars can explode at the end?
