The Week of February 13, 2012

I'm sure everyone is excited for Valentine's Day this week!  Our lessons for this week are also a cause for excitement...circumference of circles and famous astronomers!

In math, we will work together to discover the circumference of circles.  We will start by using our trusty rulers to measure circumference, then we will explore a formula that will make the whole process a lot faster.  Be ready for some homework and classwork that you will need to complete.  In addition, we will have a quiz on Thursday.  HERE is a fun online basketball game that helps you practice finding circumferences of circles.

We will start a new unit of outer-space in science this week.  We will start off by talking about famous astronomers in history, telescopes, and constellations.  Here is a copy of the powerpoint I will share with you tomorrow:

You will be given a "Planetary Pathways" choice sheet to guide your studies.  It will be due next Friday.  This Friday, you will have a vocabulary quiz on the following words:

Astronomy- the study of the universe

Year- the time required for the Earth to orbit once around the sun

Month- a division of the year that is based on the orbit of the moon around the Earth

Day- the time required for the Earth to rotate once on its axis

Telescope- an instrument that collects electromagnetic radiation from the sky and concentrates it for better observation

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

Zenith-  the point in the sky directly above the observer on Earth

Altitude- the angle between an object in the sky and the horizon

Horizon- the line where the sky and the Earth appear to meet

Light-year- the distance that light travels in one year; about 9.46 trillion kilometers

I really enjoyed reading your biome essays!  Please see me if you have any questions about the grade you earned.  

See you Monday morning,
Mr. Trent
