Our final chapter for science this year is all about the solar system. We are planning a trip to the George Bush library to see their space exhibit on the 19th. If anyone is willing to assist, please let me know.
As for the science project, each student has chosen a planet or other item from the solar system. Students are to research important information pertaining to their selected planet and create a report for the class. The information should include distance from the sun, size, any moons or rings and their names, temperature, composition, and length of 1 year in days. Any other information that is special to your planet should also be included. You may make a model, draw a diagram, create a poster, or any other visual you wish.
Don't forget to bring your labeled drawing of the sun and its atmospheric layers on Tuesday.
Have a great weekend!

B. Measured in millibars or inches of mercury
III. Increasing Altitude
A. Altitude- elevation, or distance above sea level
1. Air pressure decreases as altitude increases
2. As air pressure decreases, so does density
Sec. 4: Layers of the Atmosphere
I. Troposphere

III. Mesosphere
A. Marked by a drop in temperature
B. Middle layer of the atmosphere
C. Coldest part of the atmosphere, temps near -90C
D. Protects surface from being hit by most meteoroids
IV. Thermosphere
A. Outermost layer of the atmosphere
B. No definite outer limit
C. Very hot, up to 1800 C
D. No heat felt; not enough molecules
E. Layers
1. Ionosphere- lower layer of the thermosphere
a. Aurora borealis- northern lights

End of 5th Six Weeks is coming!
As the end of the 5th 6 weeks draws near, all outstanding work is overdue! I need anyone who still owes me any work to turn it in ASAP to receive a grade higher than 0.
We will also be having a math test on Tuesday of next week. This test will include:
1. adding, subtracting & multiplying compound measures
2. finding a % of a number
3. solving equations for x (3x= 12 what is x?)
4. degrees in a polygon or angle
5. area, perimeter, and circumference of circles, ssquares, triangles, rectangles, and parallelograms
6. order of operations
7. adding decimals
8. exponents
9. proportions
10. multiplying, adding, subtracting, and dividing decimals
11. adding, subtracting and dividing fractions
Have a super weekend!
