Learning objectives:1. To be able to describe geocentric and

heliocentric models.2. To be able to explain how scientists use

waves to find out information of the universe.

The Solar System

The Pyramid of Kukulcan twice a year creates a giant shadow that looks like a snake.

This happens of the 2 days in a year when the length of night is the same as length of daylight.

What do we know about the universe?

Geocentric Model:

What were the early beliefs about the model of the solar system?http://www.youtube.com/watch?v=iiBIFlvu-X0

Heliocentric Model:

Nicolas Copernicus came up with this model.

The church did not like this model. Why?

What is the heliocentric model?Why did the church not agree with the heliocentric

model?How did the telescope prove that Copernicus was

right?What did Galileo notice about the moons of Jupiter?

What did this make him realise?

The telescope was invented in the 16th century.

How did this discovery improve our knowledge of the universe?

The Telescope

As telescopes improved, more discoveries were made, including the planets URANUS, NEPTUNE AND PLUTO.
