Walking in the Footsteps of Galileo

Who was Galileo?

Who were Galileo’s contemporaries? Nicolas Copernicus Tycho Brahe Johannes Kepler Galileo Galilei Isaac Newton

What do our students know about Galileo?

What did science look like at the time of Galileo?

How did Galileo change the practices of science then?

The Nature of Science These are key ideas identified in the Next Generation Science Standards draft: *Tentativeness *Using empirical evidence *Making observations and inferences *Using scientific methods *Creativity *Objectivity and subjectivity

A Moon Story Anna said, "I think the Earth would show phases, but it wouldn't move across the sky." Kedric said, "I don't think we would see phases of the Earth, but it would move in the sky. It would take about a month to cross it.” Emalee said, "I think we would see the Earth move just as fast across the sky as the Moon moves across our sky when we are home on Earth. We would be able to see phases.” Tanner said, " I have a different idea. The Earth would take about two weeks to cross the sky, and it would always be full, or almost full."

Developing Explanations Based on Evidence Answer the question assigned to you. What is your claim? What is your claim? What is your evidence? What is your evidence? Explain how the evidence supports your claim. Explain how the evidence supports your claim.Share!

You will now watch a short video about Galileo's observations of the Moons of Jupiter. As you watch the video, think about what Galileo did as a scientist and why he did it. Reflecting on Galileo’s Observations

Galileo’s Notes

Reflections on the Video Why did Galileo look at Jupiter? Why did Galileo repeat his observation? What question(s) did Galileo ask? What did Galileo do that helped to answer his question(s)?

Reflections on the Video What was Galileo’s claim? What was his evidence? What were the implications of his claim? What did Galileo do with his work? How did society react to his work? What made Galileo the first modern scientist?

Optional Slide The next slide can be used instead of slide 16. It shows Night 7 instead of a cloudy night.
