How the Telescope Changed the Perspective of the World

"Everything revolves around the earth," 

said Aristotle, Ptolemy, and people for centuries.

"No, the sun is the center of our solar system," 

said Copernicus and Galileo.

These two men were arrested for their opinion.

Who was correct?

What did they base their opinion on?

Is it possible to be wrong?

How do know know for sure?

Do you think there are things that we might be wrong about?

These are the questions we grappled with as we 

looked at the modern model of the solar system.

And we made telescopes, like Galileo,

and learned how his telescope changed 

the perspective of the world!

First we looked at the two models and discussed what we noticed.

We experimented with light 

and saw how it bends, 

how it gets spread out, 

and how it is affected by mirrors, 

including convex and concave mirrors. 

We experimented with lenses. 

And we made telescopes!

One boy was asked at the end of the day 

why he was so tired and his response was, 

"Because the day was so full of discoveries."

The sun is indeed the center of our universe, 

thanks to Galileo's telescope. 

A perfect Seabury day!
