The Week of September 19, 2011

WOW, what a wonderful weekend!  The weather was amazingly beautiful, wasn't it?  I hope you are refreshed and ready for a busy week.  I will give you handouts of the copy/pasted study guides found below.  It is very important that you are focusing on your work, always having good purpose, and studying each night this week.

In math, we will learn about Stem and Leaf plots Monday.  We will review all the ways we discussed to organize data on Tuesday so we can be ready for a quiz Wednesday.  Here is what you will need to know for your quiz:

Ways to Organize Data:

Bar Graph- displays data with vertical or horizontal bars.  Used to compare data.

Line Graph-  displays data with a series of plot connected by straight lines.  Used to show change over time.

Frequency Table-  organizes data with intervals

Histogram- a bar graph that shows the number of values that occur within each interval

Line Plot- shows the frequency of data on a number line

Tally Table-  shows data as a series of tallies on a table.

Stem and Leaf Plot- show how often data values occur and how they are distributed. 

Other info. to know:

Mode:  The piece of data that appears most often in a set.

Outlier:  Data that does not follow a given trend (seems “out of place”)

ALL GRAPHS MUST INCLUDE A TITLE AND APPROPRIATE LABLES AND KEYS.  PLEAE BE ABLE TO READ AND MAKE EACH OF THESE GRAPHS.

We will be finishing up our work on the rock cycle this week, also.  Please be sure to complete at least three choices from your "Hard Rock Cafe" menu.  It will be due Friday.  In addition, we will have a quiz on the rock cycle this Friday.  Please know the following for the quiz:

Types of Rocks

            Igneous Rocks- form when hot, liquid rock (magma) cools and solidifies

Extrusive igneous rock- forms from magma that erupts onto theearth’s surface.  It is common around volcanoes.  It cools quickly on the surface and contains very small or no crystals.

                        Intrusive igneous rock- forms when magma cools below the earth’ssurface.  The magma cools slowly and forms large, visible crystals.

Sedimentary Rocks- form at or near the Earth’s surface.  It forms without the

heat and pressure that are involved in the formation of igneous or metamorphic rocks.  Formed of weathered rock/mineral fragments, crystallized minerals, or from the remains of once-living plants and animals.

Metamorphic Rocks- Forms when rocks are exposed to intense heat,

pressure, or a combination of both.

            Contact metamorphism- When a rock changes to a metamorphic rock through heating from nearby magma

                                    Regional metamorphism- When a rock changes to metamorphic rock due to the    pressure from the Earth above it.
