Our Thanksgiving break is almost here and I am certainly looking forward to our party on Wednesday, November 25th, and then filling up on turkey, dressing, sweet potato casserole, and pumpkin pie on Thanksgiving! But before we go, we have one week full of quizzes and tests to take and get out of the way. Time for a new bonus! Can you find the picture above? Hope so! It will mean bonus points on your next quiz! Ready? Set! Go!

Mrs. Smith’s 7th-12th grade classes are putting together a Christmas care package to send over to Alex Stojadinovic, son of Martha Cook, who is stationed in Afghanistan. For the next three weeks we will be collecting items from the following list to include in the box:
- Hand Sanitizer
- Good n Plenty
- Trail Mix
- Boxes of Sugar Candy (Like Sour Patch Kids)
- Individual Powdered drink mixes (to add to bottled water)
All donations will be accepted through Monday, December 14th. Thank you so much for your part in being a blessing to Alex while he’s stationed overseas.

While studying Kepler's three laws of planetary motion we encountered what appeared to be a contradiction in our physics book. After some in-depth studying into Kepler's constant what I discovered was that Equation 7.14 on the bottom of p. 153 of our text is the equation to which the statement "This equation is good only for planets, comets, asteroids, etc., orbiting the sun. It cannot be used for any planetary satellite or moon." is referring to. This statement does NOT refer to the ratio of the square of the orbital period (T) to the cube of the semi-major axis (R), found in Equation 7.13 on p. 153. Equation 7.14 is referring to finding the orbital period of a planet that is orbiting the sun. By using the time it takes for the earth to orbit the sun as well as the astronomical units (ua) [the mean distance from the earth to the sun], one can solve for the orbital period of any other planet orbiting the sun. This is a derivative of Kepler's constant given in Equation 7.13. Kepler's constant in Equation 7.13 can be applied to all heavenly bodies contained in the same system.
Each orbital system in the universe has it's own K, or Kepler's constant. Jupiter and it's moons, for example, have a different K than say, the Earth and her moon. That also means that all three of Kepler's laws apply to moons, asteroids, comets, satellites, etc. and are related proportionally to a planet, moon, asteroid, comet, or satellite that is contained in that same system. If a satellite is orbiting the earth it will orbit faster when closer to the earth, following Kepler's second law.
Now to the practice problem we worked on the board Friday during class time. We new the semi-major axis and orbital period of Europa, one of Jupiter's moons, and also the semi-major axis of Io, another of Jupiter's moons. We were then asked to calculate Io's orbital period. Simply place the ratio of Io's semi-major axis and it's period (WATCH THE EXPONENTS!!) equal to the ratio of Europa's semi-major axis and it's orbital period (Again, WATCH THE EXPONENTS!!). Solve for the unknown of the proportion using cross-multiplication and then division.
This video below will give a practice problem using the example of the moon and a satellite orbiting around the earth (both in the same system).

The Dunkin Donuts Pumpkin Spice coffee bag has been up for a while now and it's time for a brand new bonus for this next week. Many of you asked me what I was going to use that box of pinecones in my classroom for. The idea of throwing them at each other didn't quite go over very well...JUST JOKING!! In fact I had the idea of making turkey's out of them with leaves as the tail feathers. So here's what we will be making the Wednesday before Thanksgiving, courtesy of Susan B. Anderson...

NO PUMPKIN NEEDED FOR MONDAY!!
I had seven medium pumpkins donated to our World History and Geography class after the Fall Festival last night. If you do not have a pumpkin yet, no need to worry. I have one for you already. If you bought yours already, then by all means bring it in tomorrow, November 2nd. Can't wait to see what you've come up with to paint your new pumpkin!!
