Please complete the definitions and Regents questions from the LinkViewer if you were unable to do so in class (it’s a big file, so it may take a couple minutes to load, you can try right-clicking and choosing “Save as”). Additionally, please review and study the following terms as you will need to know them for the upcoming test.

  • terrestrial planet
  • jovian planet
  • comet
  • meteor
  • asteroid
  • moon
  • solar system
  • star
  • orbit
  • perihelion
  • aphelion

Tuesday, January 10, 2012

Today in class, we created our solar system object slides, completed our solar system data tables, and reviewed the Solar System Data ESRT. For homework tonight, please complete all the questions found on pages 186-189 in your ESRT Workbook (the skinny green book). We will go over the answers tomorrow.

Monday, January 9, 2012

Today in class, we completed, reviewed and submitted the ellipse lab. We then turned our attention to the details of the solar system. We will spend the next couple days looking at the characteristics of solar system objects, and how they move. Here is the data table to help you complete the solar system data lab in class.

For homework, please complete a (minimum) one paragraph biography of the object you were assigned in class. Include all information you think is relevant and interesting. You may use this NASA site for information and links.

Friday, January 6, 2012

Today in class, we completed the ellipse lab. Remember, the shape of all orbits in the Universe is elliptical. Some are very oval, others are very circular. To better describe the shapes of an ellipse, we use the mathematical eccentricity calculation. Eccentricities closer to 0 represent more circular orbits, while those closer to 1 are more stretched out.

For homework tonight, please complete these Regents questions. We will go over them on Monday.

Here is a copy of the Astronomy test (Version 1 and Version 2) for those of you who want to do corrections. Corrections are due next Friday.

I AM FINISHING UP THE GRADING OF THE PROJECTS. PLEASE CHECK ENGRADE FOR YOUR GRADE. IF YOU HAVE AN “M” FOR A GRADE, PLEASE SEE ME ON MONDAY AS THERE IS SOME ISSUE WITH YOUR PROJECT, EITHER I DIDN’T GET IT, OR IT IS NOT WORKING PROPERLY. LET’S TAKE CARE OF THIS ASAP.

Thursday, January 5, 2012

Today in class, we explored the elliptical orbits as proposed by Johannes Kepler. We began a lab in which we drew and analyzed elliptical orbits. There is no homework for this evening.

OuterOrbits

Wednesday, January 4, 2012

Today in class, we reviewed the transition from a geocentric to a heliocentric model of the Universe. We explored the evidence put forth by Galileo and his telescope. Finally, we took a look at the contributions of Kepler who said that planets orbit the Sun along elliptical (slightly oval) paths. He explained how the closer a planet was to the Sun, the faster it traveled.

For homework, please complete the Regents questions found here. Either print the pages and bring them in, or write your answers on looseleaf so we can check them in class.

early astronomy
Today in class, we began to explore the development of the field of astronomy. We looked at how our views of the Universe and how it functions have changed over time. We first believed in a geocentric universe, in which the Earth was stationary in the center with all objects revolving around it. As our understanding evolved, we transitioned to a heliocentric model in which the Sun is in the center and all objects, including Earth, revolve around it.

For homework, please complete the Regents questions found here. Either print the pages and bring them in, or write your answers on looseleaf so we can check them in class.

Happy Holidays!

As we approach the holiday break, I thought I would leave you with a heartwarming tale about the joys of the Holidays as experienced in far-away lands. This is known as the legend of the Krampus…

The Krampus is a holiday fixture that’s popular in the Germanic countries. Created to really enforce the whole “better watch out” Christmas ideology, the Krampus is the pure evil that must exist to balance out St. Nick’s pure goodness. Legend has it that when the Krampus discovers a bad-apple kid, he grabs the tot with his tongue, throws the kid in a sack, and takes them back to his home for dinner.

Here’s what the Krampus looks like…

Wednesday, December 14, 2011

Today in class, we completed our discussion of energy, the doppler shift, and the Big Bang. Remember, the Big Bang is thought to have occurred sometime between 13 and 15 billion years ago. The evidence supporting this theory includes the fact that everything is red-shifted (the Universe is expanding) and the observation of cosmic background radiation.

WMAP_2010

For homework, please completed the TestWizard quiz entitled “Universe Homework #1.” I will be closing this assignment tomorrow at 3pm.


*Note: Your natural disaster projects are due on Monday, December 19.

Tuesday, December 13, 2011

Today in class, we continued our discussion of energy, the Doppler shift, and how this supports the Big Bang theory. For homework tonight, please complete the Doppler Shift of Galaxies Lab, including the 12 practice Regents questions at the end.

Here is the information we should understand at this point:
  • The theory of the creation of the Universe which states that all matter and energy was once together in one point which exploded in all directions forming the Universe.
  • Whenever an object’s visible spectrum is shifted to the red side (red-shifted), it means the object is moving away from the observer. If it is shifted to the blue side (blue-shifted), it means the object is moving towards the observer.
  • This spectrum from this “distant star” is shifted to the right, towards the infrared wavelengths, and is
    dopplerspec
    therefore called “red-shifted”. This means that this star is moving away from the observer. If the pattern of spectral lines were shifted towards the ultraviolet, or “blue-shifted”, it would signify that the star is moving towards the observer.
  • Every object in the Universe is red-shifted, meaning that the Universe is expanding

*Note: Your natural disaster projects are due on Monday, December 19.

Monday, December 12, 2011

Today in class, we began exploring energy and how it can be used to determine whether a celestial object is moving towards us or receding away from us. Here are the key ideas from class:

  • All objects emit energy, which travels in waves.
  • What makes one type of energy different from another is it’s wavelength.
  • When an object moves, the wavelength of the energy it’s emitting is changed by that motion.
  • We can determine if an object is moving by looking at it’s spectrum to see if it’s wavelength has shifted.
  • Objects who have spectra shifted towards the red-end of the spectrum are moving away from us, while those shifted towards the blue end of the spectrum are approaching.
  • Almost all objects in space are red-shifted, meaning the Universe appears to be expanding.

For homework, please print and complete this worksheet. You will need to use your ESRT to complete the questions.
