Collaborate with other people in class and write down what they tell you on your summary of articles worksheet.
Let them tell you about the other 4 scientists you didn’t research.
Claudius Ptolemy
Galileo Galilei
Nicolaus Copernicus
Isaac Newton

2. Pick an astronomer to explore further
Get in groups of 4 and talk about what your scientist would think about the other 5 scientists theories. Would they agree or disagree? Jot down some notes:
Claudius Ptolemy
Galileo Galilei
Nicolaus Copernicus
Isaac Newton
Henrietta Leavitt
Edwin Hubble

3. You will be representing your astronomer in a discussion about different theories in astronomy.
Write down for discussion:
What are your astronomers beliefs?
What technology did your astronomer have available to them?
What other astronomers would your astronomer agree with and why?
What other astronomers would your astronomer disagree with and why?

4. Think. Pair. Share.
With your group, talk about the changing views of the universe. Why/how did they advance our thinking?

mentor/university pushed their thinking
Once discussion is finished, write a response individually.
