Big Idea: Exterritorial energy and materials influence Earth's systems and the position and motion of the Earth within an evolving solar system, galaxy, and universe.
Learning Targets:
- I can describe the position and motion of our solar system in our galaxy and the overall scale, structure, and age of the universe.
- I can describe how the Big Bang theory accounts for the formation of the universe.
- I can explain how observations of the cosmic background radiation have helped determine the age of the universe.
- I can differentiate between the cosmological and Doppler red shift.
- I can explain how the solar system formed from a nebula of dust and gas in a spiral arm of the Milky Way Galaxy about 4.6 Ga (billion years ago).

How the Universe Works: Big BangScientists discuss how the universe formed according to the big bang theory. Looking beyond our galaxy and into deep space, astronomers and physicists seek answers to questions about the beginning and end of our universe. Chronicling the formation of the universe, the program explains how energy converted to matter to create all that we see around us today. Theoretical physicists and cosmologists reveal how our understanding of the universe has changed during the twentieth century through modern technology and scientific study.

What is Redshift?In physics, redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum. In general, whether or not the radiation is within the visible spectrum, "redder" means an increase in wavelength.
Some redshifts are an example of the Doppler effect, familiar in the change in the apparent pitches of sirens and frequency of the sound waves emitted by speeding vehicles. A redshift occurs whenever a light source moves away from an observer. Another kind of redshift is Cosmological redshift, which is due to the expansion of the universe, and sufficiently distant light sources (generally more than a few million light years away) show redshift corresponding to the rate of increase in their distance from Earth.

Astronomy Blog ChallengeFor this, our next blog assignment, I'd like you to focus on space and the solar system. Please choose from one of the following options to blog about:
1. Go outside and view the night sky (on a clear night, of course). In your post, reflect upon the stars and objects you see. How do you feel when looking at the stars? 2. Use a star chart to find a constellation you recognize and want to find in the night sky. Now, go outside and find the constellation in the night sky. Blog about the constellation you observed, where (north, south, east, west, horizon, etc.) it was in the sky, what it looks like, what stars make up the constellation and any other interesting pieces of information you find about the constellation. 3. Visit NASA's Astronomy Picture of the Day website. Look at the picture of the day and/or view pictures in the "archive". Pick a photo to reflect upon (write about what the image makes you think of, etc.). Add the image to your post and provide a link to the picture you choose so your readers can enjoy the picture, as well. 4. Choose a topic that interests you from Chapters 19, 20 & 21 that we will NOT be studying in class to learn more about; the planets, rocketry, etc. Read the information in your textbook, find resources online, etc. and tell your readers what you learned. This post is due by Wednesday, May 27th. When doing your blog post, I want you to write at least one paragraph (minimum 5 sentences) including a topic sentence telling what your paragraph is about and three sentences with supporting details answering the question you chose. You may write more than this if you want to, just do not write less. Don't forget to add a picture and/or a link where possible. I am looking forward to seeing what you have to say! |
General Blogging Tips:
1. Safety first! Never share any last names on your blog or when commenting on other student blogs.
2. Remember to use proper grammar and punctuation - this is not like texting and messaging your friends - you have a
worldwide audience.
3. Read your own post before submitting it for review. Make sure that what you wrote makes sense.
4. Use spell check before you post.
5. Write at least one paragraph (minimum 5 sentences) including a topic sentence telling what your paragraph is about and
three sentences with supporting details answering the question/about the topic. You may write more than this if you want to,
just do not write less.
6. Don't forget to add a picture/image (properly cited) and/or a link where applicable. This makes your blog post more
interesting and appealing to your readers.
