Nagel 8-2 Science/ Week of March 19th

Week of March 19th
Check out the sunspots on the Sun!  What are sunspots and how do they affect us here on the Earth?

 Pictured above is the McMath-Pierce Solar Telescope!  Yes, it is a telescope!  It is especially designed to analyze radiation from the Sun.  Look underneath the scope - what planets are peeking through?


Our Week:

Monday: 1.  4 - Study Island Tests due each Monday - we are up to 12 today - 16 by Monday 3/26  2. We are finishing up the Hubble Deep Field Lab 

Tuesday: 1.  Turn in Hubble Deep Field  2.  Begin Tools of Astronomy

Wednesday: 1.  We are outside looking through the telescope at sunspots  2.  Tools of Astronomy due Thursday

Thursday:  1.  Finish Tools of Astronomy - due today

Friday:  1.  Clips from "Independence Day"  2.  Final Exam Tuesday - here is the Study Guide:

Astronomy Final Exam
Study Guide

The exam will have 28 multiple choice questions, two 2-point questions, and one 4-point question.

Things to know:

1.  Explain why we have day and night
2.  What is the difference between rotation and revolution?
3.  Why does the Earth have seasons?
4.  Why does sunlight amount change during the year?
5.  Know the positions of the Earth, Moon, and Sun during a lunar and a solar eclipse. Why do we have eclipses?
6.  Why does the Earth have regular tides?
7.  Why do we see specific phases of the Moon?
8.  How do the positions of the Earth, Moon, and Sun affect the tides? Compare tide heights during full moon to tide heights during first quarter.
9.  What forces keep the Earth, Moon, and all of the other planets in orbit around the Sun? 
10.  What determines the life cycle of a star? Describe the life cycles of stars like our Sun and Giant stars
11.  What is the difference between the light-year (ly) and the astronomical unit (au)?  When do astronomers use each unit?
12.  What are the 3 main galaxy shapes? Be able to identify them.
13.  What does an optical telescope do?
14.  What is the difference between an asteroid, a meteor, meteorite, and a meteoroid?
15.  Why do we have meteor showers, and what causes the streaks of light?
16.  What is parallax?
17.  What is the difference between a space probe and a satellite?
18.  What are comets, and how would you describe their orbits around the Sun?
19.  How many stars are estimated to be in a galaxy?  How many galaxies are estimated to be in the Universe?
20. What characteristic of stars can tell us what particular stage a star is in?
21.  Describe 3 results of a major meteorite impact to the Earth
22.  Describe how and why shadow length changes during each season


You knew I had to show you one more auroras over Iceland image - this one was taken this month - really amazing!  How are these things caused again?

  1. Underneath the telescope are the planets Venus and Jupiter.
    Those auroras are caused by the combining of the earths magnetic field with particles from the sun

  2. What are sunspots and how do they affect us here on the Earth?
    Sunspots are the cooler areas on the sun. They affect us on Earth because their activity can sometimes cause problems in communication and navigation systems.

    What planets are peeking through?
    I think that the planets that are peeking through are Jupiter and Venus.

    How are these things caused again?
    Auroras are caused because of interactions between the Sun’s radiation and our magnetic field near the poles.

  3. 1.)Check out the sunspots on the Sun! What are sunspots and how do they affect us here on the Earth?
    The sunspots are in the middle of the sun and they are the cooler parts of the sun. They are still very hot but it is cooler than the other places. The main affect that sunspots do to Earth is damage the ionosphere which is part of the upper atmosphere.

    3.) You knew I had to show you one more auroras over Iceland image - this one was taken this month - really amazing! How are these things caused again?
    is a natural light display in the sky, in the high latitude region, these are caused by collisions of energetic charged particles with atoms.

  4. When the sun has a solar flare the suns radiation comes near the earth and makes these auroras.
