The Wonderful Week of March 12, 2012

There are a lot of things happening this week that have me very excited!  First, I will be going to Cumberland Island on Tuesday with a  few other science teachers to study erosion on the barrier island.  On Friday, Mr. Brandon and myself will fly to Washington DC to attend a science conference.  You will have a substitute teacher on Tuesday and Friday, and I am expecting exceptional grace and courtesy reports.  I'll be sure to take a lot of pictures and put them on the blog so you can share what I am seeing on Cumberland Island and in DC!

This week at Ellis we will continue to study surface area of cylinders in math.  As you know, the more we practice a concept, the better we will get at it.  I have a feeling we will all be surface area experts by the end of this year!  Be expecting some math homework and a quiz on Thursday.  I've notice a lot of people using Ten Marks to help practice their math work!  This is WONDERFUL!  Keep it up!

In science, we will focus our next two weeks of instruction on stars and galaxies.  On Monday, I will share with you some information on the lifecycle of stars.  Here's a preview of what we will be taking about:

You will get a choice sheet (Seeing Stars) to complete for next Friday as well as the following vocabulary words that you will need to know for a quiz this Friday:

Apparent Magnitude- the brightness of a celestial body as seen from earth.  The lower the number, the brighter the planet or star.

Constellation- a region of the sky that contains a recognizable star pattern and that is used to describe the location of objects in space.

Black hole- an object so massive and dense that even light cannot escape its gravity

White dwarf- a small, hot, dim star that is the leftover center of an old star.

Supernova- a gigantic explosion in which a massive star collapses and throws it outer layers into space.

Galaxy- a collection of stars, dust, and gas bound together by gravity

Globular cluster- a tight group of stars that looks like a ball and contains up to 1 million stars.

Nebula- a large cloud of gas and dust in interstellar space; a region where stars are born.

Quasar- a very luminous object that produces energy at a high rate; they are thought to be the most distant objects in the universe. 

Protostar- a ball of gas and dust.  Gravity pulls the gas and dust together, and its center gets hotter (the first stage of the lifecycle of a star)

Let's get this week going!

See you tomorrow,
Mr. Trent
