Team 8-2 Science/Week of March 26th

Week of March 26th
Astronomy Final Exam Week!






Barred Spiral Galaxy 


Our Week

Monday:  1.  Exam Review  2.  16 Study Island Tests due today!

Tuesday:  Astronomy Final Exam

Wednesday:  1.  Motion and Forces begins - bring your workbook to class each day  2.  We will begin our unit with a test of your reaction speed, and you are going to design and build a windmill  3.  You might need some supplies from home, but I am gathering materials for you also

Thursday:  We will beginning designing our windmills

Friday:  No regular classes

Here are some pretty cool things to look at that have to do with motion!  








Question of the Week

 In 1971, Astronaut David Scott during the Apollo 15 Moon Mission,  dropped a feather and a hammer at the same time to prove a very important principle of physics.    Watch this video clip and decide what is going on and why.  Use your knowledge of the Moon to help you come up with the solution for what you are seeing.

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

Evolution of the Moon - really cool video showing theories about our Moon's history 

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?

Week of March 12th
What you are looking at is the Sombrero Galaxy - shown in infrared radiation - this is one of my favorite galaxies!  What type of galaxy is this?  First you have to know how galaxies are classified - stay tuned! Par
 Our Week
Monday:  1. Spectroscope Lab due and turned in  2.  Gizmo on Spectral Analysis checked for completion  3.  4- Study Island Tests due - some of you are slacking!   4.  Parallax View due first thing Tuesday!
Tuesday:   1.  Parallax View checked and gone over  
2.  "Galaxies"  3.  Interactive: Question Sheet due Wednesday
 

Wednesday:  1.  Hubble Classification 2.  Lab: Hubble Deep Space - due Friday - Use the links below to help you with the Hubble Deep Field Lab
Estimating the number of objects in the Universe! 
Classifying objects by color and shape 

Hubble Site 

Thursday:  1.  Continue Hubble Deep Space Lab

Friday:  1.  Hubble Deep Space due  2.  "Tools of Modern Astronomy" 3.  Tools Mini-Project due Monday (tentative)

The Amazing Hubble!

The Hubble Space Telescope was launched from the Space Shuttle in 1990!  It has been orbiting the Earth, gathering data, for 22 years!  Discoveries, made by Hubble, have revolutionized Modern Astronomy! 

Question:  Why has the Hubble Space Telescope been able to tell us so much about objects in space? 

Some of my favorites from the Hubble Gallery!

Crab Nebula

Horse Head Nebula

Ant Nebula
Sauron's Eye (Young Solar System forming around a star)

Barred Spiral Galaxy - Like Our Milky Way!
Planetary Nebula
Mystic Mountain

Question of the Week

All the Colors of the Sun
The above absorption spectrum belongs to our Sun.  What colors of light seem to be the most brightest?  Look closely, are there some colors missing?  

In 1870, a certain common element was discovered in the spectrum of our Sun that later led to its discovery on the Earth.  Yes, it is the element that makes our voices sound like Christmas Elves if we breathe it in!
