AC9S6U02 • Year 6 Science
describe the movement of Earth and other planets relative to the sun and model how Earth’s tilt, rotation on its axis and revolution around the sun relate to cyclic observable phenomena, including variable day and night length
Learning intention: Use models to connect rotation, revolution and axial tilt to day, night, seasons and changing daylight length.
Curriculum focus: Describe the movement of Earth and other planets relative to the Sun and model how Earth’s tilt, rotation on its axis and revolution around the Sun relate to cyclic observable phenomena, including variable day and night length.
Task: A globe turns once while a fixed lamp represents the Sun. A marked city moves from the lit side to the dark side. Which movement is mainly responsible?
Model reasoning: Earth rotating on its axis Rotation carries locations into and out of sunlight, producing day and night.
Task: A globe turns once while a fixed lamp represents the Sun. A marked city moves from the lit side to the dark side. Which explanation is scientifically accurate?
Model reasoning: Rotation carries locations into and out of sunlight, producing day and night.
Task: A globe rotates beside a fixed lamp. What does this model represent well?
Model reasoning: The changing lit and unlit halves as Earth rotates. Models highlight selected relationships rather than copying every feature of reality.
Task: A globe rotates beside a fixed lamp. Which limitation should be stated?
Model reasoning: The globe and lamp are not to scale and the turn may be much faster than one day. A useful model can still omit scale, time or three-dimensional motion.
Task: A student claims, “The Sun travels around Earth each day.” Which correction is best?
Model reasoning: Earth’s rotation makes the Sun appear to move across the sky; the daily cycle is not a daily orbit of the Sun around Earth.
Task: The marked city continues rotating from the dark half toward the lit half. What should the model predict?
Model reasoning: Sunrise will occur as the city turns into the illuminated half. Cyclic phenomena follow repeatable motion and orientation.
Earth rotates about once each day, producing day and night. Earth revolves around the Sun about once each year. Its axis stays tilted in nearly the same direction as it revolves.
A hemisphere tilted toward the Sun receives more direct light and longer daylight; six months later it is tilted away. Distance from the Sun is not the cause of seasons.
Other planets also rotate and revolve with different periods. Globes, lamps, diagrams and simulations reveal relationships but usually distort sizes, distances, speeds or time.
Australia has longer days and summer when the Southern Hemisphere is tilted toward the Sun. Northern and Southern Hemisphere seasons are opposite at the same orbital position.
Explain one daily and one yearly cycle with the correct motion, then name one limitation of a globe-and-lamp model.
Evidence of mastery: The student distinguishes rotation, revolution and tilt, explains southern-hemisphere daylight and seasons causally, and evaluates a model without treating it as exact scale.

Crash Course Kids — Use Earth’s tilt and its movement around the Sun to explain seasonal patterns.
As you watch: Why does the angle of sunlight matter more than Earth’s distance from the Sun?
