Astronomy (Period 7/8)

Course Description

 
Astronomy is the branch of science that deals with celestial objects, space, and the physical universe as a whole.

 

Astronomy is the study of the universe, namely the objects we observe, like the Moon, Sun, and planets in our Solar System; stars; our Milky Way Galaxy, and other galaxies; and, a host of other celestial objects and phenomena, like nebulae, and black holes.

Astronomy is a multidisciplinary science. It is intertwined with the study of physics, chemistry, mathematics, computer science, geology and biology.

Unlike most other fields of science, astronomers are unable to observe a system entirely from birth to death; the lifetime of worlds, stars, and galaxies span millions to billions of years. Instead, astronomers must rely on snapshots of bodies in various stages of evolution to determine how they formed, evolved and died. Thus, theoretical and observational astronomy tend to blend together, as theoretical scientists use the information actually collected to create simulations, while the observations serve to confirm the models — or to indicate the need for tweaking them.

Astronomy is broken down into a number of sub fields, allowing scientists to specialize in particular objects and phenomena.

Shedding Light on Shadows

We will go outside for this activity. 
You will pair up and complete the activity. 
You will be able to work on the interactive from last class in between the times of collection of data....see attached pdf.
Read over the activity before coming to class.
 
This is the link for the eclipse interactive:
 
3) Eclipse Interactive  (link above)
What's the difference between lunar and solar eclipses? What causes each kind of eclipse? Why don't we see eclipses more often? What would they look like if the angular diameters of the Moon and the Sun weren't so close? Unlock the secrets of eclipses with this Interactive.
 
We will go out as soon as the attendance is taken...
