Heliocentric and Geocentric videos

We have been looking at how the Science has changed over many centuries as more evidence has been discovered on how our solar system works.  For thousands of years people believed that the Earth was the centre of the solar system and indeed the universe!  By observing the Sun during the day it seemed obvious that it was moving around the earth (geocentric).

Now we believe nothing but the heliocentric model.  It shows that ideas in science do change over time but big discoveries can often take a long time to be accepted and proven!  The children have made some videos that show some of the different scientific theories over the centuries, take a look!
