Star Life Stages Flowchart Interactive


What Happens When a Star Runs Out of Hydrogen


Week of February 27th

Supernova 1987A

Pictured above are new mysterious rings around one of the largest supernova explosions first seen in 1987.  The Hubble Space Telescope keeps an eye on this amazing object every few years - any ideas what could be causing these rings?  You will be watching a video on Monday that could help you answer this question.

Our Week


Monday:  1.  Video: "Life and Death of Stars" - Notes Sheet due Tuesday  2.  All 4 assignments from last week are due Tuesday - they are: 

• p. 198 1-4
• Life Stages of Star Flowchart from interactive
• Quesions 1-8 When Stars Run Out of Hydrogen - interactive
• Orion Nightsky Homework - you are to find Orion in the nightsky - look for 3 stars in a row after 8 pm in the south/southeast - draw and label the constellation - at least 7 of the stars - compare our Sun with Betelgeuse and Rigel only- set up a table to include at least - temperature, color, age, and size

Tuesday: (We will have shorter classes due to our trip to the High Schools)  1.  4 assignments will be gone over and collected  2.  Study Island Homework Begins! 3.  Video Notes sheet checked - video discussed - finished?  

Wednesday:  1.  Hertzsprung-Russell Hall graphing begins 

Gizmo: H-R Diagram

Thursday:  1.  H-R Graphing Continued 2. Review for quiz

Friday:  1.  Quiz over distances in space and star life stages  2.  Study Island Progress Check

Question of the Week

Pictured above is a pretty amazing place about 1,500 light years away!  Look closely at this object's stars - what do you think this is, and what is going on within it?

Week of February 13th

This is called a "Snow Moon"

 

The Week

Monday:  1.  Finish Solar System in Hall - due end Tuesday!

Tuesday:  1.  Check Solar System in Hall  2.  Begin Celestial Movement - due end of class Wednesday

Wednesday: 1.  Finish Celestial Movement Table - due today!

A Year of the Sun Interactive 

Friday:  1.  Finish Year of the Sun

Homework For Week - due Friday

Pictured above is the Winter Constellation Orion - Orion is made up of some very interesting stars: Betelgeuse, in the top left above the 3 stars in a row, it is classified as a  red supergiant, and Rigel in the bottom right is a blue-white supergiant

 Your assignment is to - 

1.  Find Orion in the evening sky - draw a detailed labeled diagram - with the help of the internet, of course.  Label the main stars of Orion - and there is a nebula floating around up there also - where is that located?

2.  You need to then compare our Sun to Betelgeuse and Rigel - how is our Sun classified compared to them - find differences in size, age, color, temperature 

8-2 Science/Week of February 6th

Current Science

Red Auroras over Australia! This is a result of last week's solar flare outburst from the Sun.  Red Auroras occur due to oxygen atoms in the lower atmosphere getting charged up by the solar radiation.
Take a close look at the objects in the sky - would the night sky in the southern hemisphere be different than the sky we are seeing?  Explain your reasoning.

Check out the Moon's movements through one complete Moon Phase cycle - 29.5 days; what do you notice about how the Moon revolves around the Earth?  

One complete Moon Phase Cycle "Lunation"

Upcoming

Our busy solar system!  The thin blue lines represent the orbits of the main planets - red dots indicate Earth-crossing asteroids- green dots are asteroids in the asteroid belt - blue squares indicate comets, and blue dots represent asteroids that follow Jupiter around!

Our Week:

This week we will be taking a look at how the Sun is moving through space bringing the solar system with it.  We will also learn about the huge distances in space and how they are measured.

Monday:  1. Give back last quiz and homework - go over  2. Finish up Tides' Graphing questions - turn in graph with data/question packet  3.  "Our Sun and distances in space"  4.  Homework for the week: use the links below of visualizations of the Solar System and the Universe to complete the question sheet handed out in class - due Friday!

Question of the Week

Pictured above is Comet Garradd rocketing through our solar system.  Garradd is about 12.5 light-minutes from the Earth. 1) If one light-minute is approximately 18 million kilometers, how far away from the Earth is this comet?  2) What do you think a 

light-minute is, exactly?
