Science ideas I need to know Astronomy Year 9 The Earth, the Sun and the Moon Science ideas I need to know Start of Unit End of Unit I know this I know some of this I need to learn this I know this Describe the daily and annual movements of Earth Understand that the Earth orbits around the Sun, like the other planets, and the Moon orbits around the Earth Understand how the length of a day depends upon the speed of its rotation on its axis Understand how the length of a planets year depends upon its time taken to orbit the sun once Understand that the Earth orbits in an Ellipse (extension) Understand that the tilt of the Earth’s axis causes seasons Relate the Lunar cycle to the phases of the moon Understand the Causes of solar and lunar eclipses Appreciate that Eclipses occur when one body in space moves into the shadow of another body. Know that Solar eclipses occur when the new Moon passes between the Sun and Earth. Know that Lunar eclipses occur when a full Moon moves into the shadow of the Earth. Understand that Tides on Earth are caused by the gravitational pull of the moon (and to a lesser extent, the Sun.) Understand Spring or Neap tides are created due to the positions of the Moon and the Sun in relation to Earth Identify Visual objects in the New Zealand night sky (southern cross, Matariki - the Pleiades, Moon) Appreciate because of Earth’s rotation the stars are not in the same place throughout the night Outline how energy is produced by the sun Explain what a light year is and how astronomers use it
