Our Place In Space: Explaining Our World
a) Draw and label a diagram of what you think the solar system looks like.
b) The tides and eclipses are caused by the positions of the Earth, the moon and the
Sun. What do you think is happening when the tide changes and when an eclipse
occurs?
Early ideas in astronomy Indigenous Australian astronomy
Astronomy is the study of stars, planets and other objects that make up the universe.

The _ _ _ _ _ _ people of _ _ _ _ _ _ Land explain the _ _ _ _ _ _ _, sunset and _ _ _ _ _ _ _

from east to west. At the end of her journey to the western

Walu uses _ _ _ ochre to decorate her face and body; when some of the red _ _ _ _ falls
onto the clouds, this causes the red sunrise and red _ _ _ _ _ _.

Aboriginals left evidence of their dreamtime stories in rock carvings.
Go to this site and read about the rainbow serpent and devil fire. Answer these questions.
1. Write a few sentences describing these events.
2. How is Aboriginal dreamtime similar to biblical stories? What biblical story do they
refer to in the article?

Greek’s discovered that the Earth is _ _ _ _ _ _ _ _ _. The Greek _ _ _ _ _ _ _ _ _ _ _
Eratosthenes measured the _ _ _ _ _ _ _ _ _ _ _ _ _ of the Earth to within about _ _ _ kms.
4 BC. Aristotle developed the _ _ _ _ _ _ _ _ _ _ model which has the Earth as the centre of
the Universe and the sun and _ _ _ _ revolving around it. This _ _ _ _ _ was accepted as
people who studied the _ _ _ _ _ sky saw _ _ _ _ _ _ _ _ _ bodies passing over the Earth.
5BC. Aristarchus developed the _ _ _ _ _ _ _ _ _ _ _ _ model that states that the sun was
fixed and all the _ _ _ _ _ _ _ , including the _ _ _ _ _ , orbited it along _ _ _ _ _ _ _ _ paths.
He noted that, _ _ _ _ a day, the moon _ _ _ _ _ _ _ _ around the Earth and the Earth
_ _ _ _ _ _ _ on its _ _ _ _.
Hipparchus (190-120BC) made _ _ _ _ _ _ _ _ _ observations of star positions and created a
catalogue of stars.
Ptolemy (AD 85-165) proposed another geocentric _ _ _ _ _. He believed that Mercury,
_ _ _ _ _, Mars, _ _ _ _ _ _ _ and Saturn, together with the moon and the _ _ _ , revolved
around the Earth.

Copernicus (1473-1543) proposed that the sun is stationary near the _ _ _ _ _ _ of the
universe. His _ _ _ _ _ _ proposed that the Earth _ _ _ _ _ _ _ on its _ _ _ _ once daily and
_ _ _ _ _ _ _ around the sun once a year. He suggested that the _ _ _ _ _ _ _ the radius of
a planet’s _ _ _ _ _ , the longer it took for the planet to orbit the _ _ _.
Kepler (1571-1630) supported Copernicus’s _ _ _ _ _ _ _ _ _ _ _ _ model and applied
mathematics to the observations of _ _ _ _ _ _ _ _ _ _ _ who proceeded him. He proposed
three theories to explain the _ _ _ _ _ _ of planets. His theories are now Kepler’s Laws.
Kepler’s First Law describes the motion of _ _ _ _ _ _ _ as ellipses.
Kepler’s _ _ _ _ _ _ Law explains how the _ _ _ _ _ of an orbiting planet depends on its
_ _ _ _ _ _ _ _ in an _ _ _ _ _ _ _ _ _ _ orbit.
Kepler’s Third Law describes how planets more _ _ _ _ _ _ _ from the sun take _ _ _ _ _ _ to
orbit the sun.
Galileo Galilei (1564-1642) In 1609 built his own telescope to study the night sky.
Described the _ _ _ _ _ surface as uneven, with craters and _ _ _ _ _ _ _ _ _ for the first
time. He observed Jupiter and saw four star-like objects which he inferred where moons.
Galileo’s observations weakened Ptolemy’s model as the Earth was clearly not the centre of
planetary motion. This brought him into conflict with the Church, and he was forced to
recant(take back) his belief in the Copernican system and live his life under house arrest.

Why would the Church not want Galileo’s observations widely accepted by the general
public? Do you know what life was like in 1600’s? This website gives you an insight into the
times these scientists were proposing these ideas.
