Science 1.15 Demonstrate understanding of the effects of astronomical cycles on planet Earth

Achievement criteria

The type of achievement you will reach is decided by the way you answer each question.  From your answers the assessor will assess your understanding of the topics of the achievement standard.

On this page: Achievement | Achievement with Merit | Achievement with Excellence

Achievement

Demonstrate understanding of the effects of astronomical cycles on planet Earth.

This involves describing astronomical cycles and the effects on planet Earth using information, visual representations, and data.

Astronomical cycles are:

  • the spin of Earth
  • the orbit of Earth around the Sun
  • the orbit of the Moon around Earth
  • the effect of Earth’s tilt and the heating effect of the Sun.

Effects on Earth include:

  • day and night
  • seasons
  • changes of temperature during the day and night
  • seasonal changes at the North and South poles, latitude of New Zealand, tropics of Cancer and Capricorn, and the equator
  • formation and direction of winds in the Southern hemisphere – direction of surface ocean current flows in the Pacific Ocean
  • phases of the moon
  • formation of tides
  • neap and spring tides.

You will need to source information for their works using resources such as class notes, online searches, books, and magazines.

Achievement with merit

Demonstrate in-depth understanding of the effects of astronomical cycles on planet Earth.

This involves explaining astronomical cycles and the effects on planet Earth using information, visual representations, and data.

Make sure you can meet the requirements for Achievement.

Achievement with excellence

Demonstrate comprehensive understanding of the effects of astronomical cycles on planet Earth.

This involves explaining thoroughly links between astronomical cycles and the effects on planet Earth using information, visual representations, and data. It may involve elaborating, applying, justifying, relating, evaluating, comparing and contrasting, or analysing to explain thoroughly links between key stages of the event.

Make sure you can meet the requirements for Merit.
