What causes day and night on Earth?

Earth’s rotation on its axis.

100

A solar eclipse happens when the ______ blocks the Sun.

Moon.

100

What does the geocentric model place at the centre of the solar system?

Earth.

100

Which culture used constellations like the Emu in the Sky for navigation?

Aboriginal and Torres Strait Islander peoples.

100

What information goes on the x-axis of a graph?

The independent variable (the factor that we change in the experiment)

200

Why does Australia experience summer when the Northern Hemisphere has winter?

Because Earth’s axis is tilted, so different hemispheres receive different angles of sunlight.

200

Which eclipse happens when Earth blocks sunlight from reaching the Moon?

Lunar eclipse.

200

What does the heliocentric model place at the centre of the solar system?

The Sun.

200

Name one piece of technology that has helped us understand the solar system.

Telescope, space probe, satellite, or spacecraft.

200

What information goes on the y-axis of a graph?

The dependent variable (the results)

300

True or false: The Earth is closer to the Sun in summer than in winter.

False – seasons are caused by Earth’s tilt, not its distance from the Sun.

300

What are the two different shadow regions called during an eclipse?

The darkest shadow and the lightest shadow
300

Which famous astronomer strongly supported the heliocentric model:

a) Albert Einstein

b) Nicolaus Copernicus

c) Ptolemy

d) Galileo

b) Nicolaus Copernicus

300

Explain how telescopes improved our understanding of the solar system.

They let us see planets, moons, and stars in detail, proving the heliocentric model and discovering new objects.

300

Why is it important to label the axes of a graph?

So we know what the data represents and can interpret the graph correctly.

400

Explain why Earth’s tilt is important for seasons.

The tilt changes the angle and intensity of sunlight, creating warmer or cooler temperatures in each hemisphere.

400

Explain why we don’t see an eclipse every month.

The Moon’s orbit is tilted, so the Sun, Moon, and Earth don’t line up perfectly every month.

400

Why was the geocentric model widely believed for so long?

Because it matched observations of the time and was supported by the church and cultural beliefs.

400

Describe one way Aboriginal and Torres Strait Islander peoples used astronomy.

Navigation, seasonal calendars for food, storytelling, or cultural ceremonies.

400

Why should you draw a smooth line (or best-fit line) instead of joining the points with a zigzag?

Because the line shows the overall trend/pattern of the data, not just the individual points.

500

Use a diagram or description to explain how sunlight angles affect temperature in different seasons.

In summer, sunlight hits more directly (higher angle), producing more concentrated heat; in winter, sunlight is spread out (lower angle), producing less heat.

500

Look at a diagram of an eclipse. Identify whether it is solar or lunar and justify your choice.

 

Lunar eclipse- sun, Earth, moon

500

Which model of the solar system does the picture below represent?


Heliocentric model

500

How have space probes or satellites changed our understanding compared to older methods of observation?

They give direct data from space (e.g. photos, measurements, surface composition), allowing more accurate knowledge than Earth-based observations.

500

A student’s line graph has all the correct points plotted but no title. Why is a title important, and what should a good graph title include?

A title tells the reader what the graph is about. A good title should describe both variables (e.g. “Effect of Time of Day on Temperature”).
