Major Concepts in This Unit:
How do Scientists Describe Earth's Position in the Universe?
- What evidence exists to support the BIG BANG theory?
- How does the nebular hypothesis explain the formation of the sun, planets and natural
satellites?
- Where do we fit in to the "Big Picture" of the Universe?
What Observations of Space can be made from Earth?
- What are the daily motions of the stars? Why do the stars appear to
move as observed?
- What is the daily motion of the sun across the sky? How is this
motion explained?
- How does the path of the sun change with the seasons?
- How does the length of daylight vary with the seasons?
- What causes the change of seasons as observed in New York State?
- What are the moon phases? What motion causes us to see the moon
differently each night?
- How do the Coriolis Effect and the Foucault pendulum support the idea
that the earth moves in space?
How are Earth's Motions described in the Heliocentric Model?
- What is an ellipse? How can it be described mathematically?
- How does the distance between the Earth and Sun vary during one
revolution? Does this changing distance have an effect on the change
of seasons?
- How does the Earth's orbital velocity vary during a revolution?
- What is the effect of changing distance between the Earth and Sun have on
the force of gravity?
- What does earth's orbit resemble when drawn to scale?
Where do WE fit in to the "Big Picture" of the Universe?
Tour of the Solar System PowerPoint
- What evidence do scientists use to support the "big bang" theory and the
nebular hypothesis?
- How is our star, the sun, described by astronomers?
- In what galaxy does our solar system exist? Where are we in that
galaxy?
- What unit do astronomers use to describe distances? Why is this unit
so difficult to understand?
- ARE WE ALONE? Explain your answer!
