Moon Phases

Science · Space Exploration · conceptual

Observe and describe the Moon's changing shape over about a month, recognising that it goes through a repeating cycle of phases from new moon (invisible) to full moon (complete circle) and back again

What mastery looks like

  • Describe that the Moon appears to change shape over about a month
  • Name or draw at least three phases: new moon (dark), half moon, and full moon
  • State that the pattern repeats — the Moon goes through the same shapes again and again

Check your understanding

If you asked Moon Phases to look at the Moon several nights in a row, could they notice that it changes shape and describe the pattern?
