Science Space Explorationusually ages 9–11

Changing Ideas About Space

Understand that ideas about the solar system changed over time: ancient people believed Earth was at the centre (geocentric model, Ptolemy), until Copernicus proposed the Sun was at the centre (heliocentric model), later confirmed by Galileo’s telescope observations

How to tell they’ve got it

Tick these off as you see them — no test required.

Describe the geocentric model (Earth at the centre) and name Ptolemy as its main proponent
Describe the heliocentric model (Sun at the centre) and name Copernicus as the person who proposed it
Explain that Galileo used a telescope to find evidence supporting the heliocentric model (e.g. moons orbiting Jupiter)

Try this together

Can your child tell you that people used to think the Sun went around the Earth, and explain how scientists like Copernicus and Galileo changed our understanding?
