Science – Hour _____ Date:_________ Name:____________________ Historical Models of the Solar System Science Fusion Lesson Guide Directions: Go to the following website. Follow the instructions on the 10 slides to complete this handout. http://tinyurl.com/qxa8fph Slide 1 1. Click on each vocab word and write its definition. solar system: ___________________________________________________ ___________________________________________________ heliocentric:____________________________________________________ geocentric: ____________________________________________________ parallax: ______________________________________________________ ______________________________________________________ Slide 2 2. True or False Ancient people noticed that planet’s positions seemed to change compared to the location of the stars. Slide 3 3. What are 4 things that exist within a solar system? _______________________________ _____________________________ _______________________________ _____________________________ 4. What 3 things helped astronomers create their models of the solar system? _______________________________ _____________________________ _______________________________ 1 5. Geo means _______________, so in the geocentric model of the universe, _________________ is the center of the solar system and everything else ________________ around it. 6. The ___________________ model puts the sun at the center of the solar system. 7. True or False (circle) At the present time, scientists use a geocentric model. Slide 4 8. Matching _____Aristotle a. thought planets traveled on a separate circular path as they revolved around Earth _____Aristarchus b. used Venus’s phases as a reason why planets orbited the Sun rather than Earth _____Ptolemy c. had complete mathematical explanations for the heliocentric model _____Copernicus d. said Earth couldn’t be moving since we didn’t feel it _____ Kepler e. created 3 laws of planetary motion _____Galileo f. figured out Sun was larger than Earth so it would make more sense for Earth to revolve around Sun Slide 5 9. Why did scientists long ago create incorrect hypotheses of the solar system? _________________________________________________________________ 10. True or False (circle) The solar system has changed over time, which is why the models of the solar system have changed, too. Slide 6 11. True or False (circle) A star seems to have 2 different backgrounds when viewed months apart because it is viewed in different locations of Earth’s orbit. 2 Slide 7 12. Put the scientist’s name in the appropriate box. Heliocentric Geocentric Slide 8 13. Galileo observed phases of Venus. What phase would he view if Earth, Venus, and the Sun were all lined up? Slide 9 14. Explain why parallax was a problem in proving a heliocentric model of the universe. ___________________________________________________________________ ___________________________________________________________________ ___________________________________________________________________ Slide 10 15. What 2 main facts do we know about our solar system now? _____________________________ _____________________________ 3
