1. Everyday is a Holiday!
National Pretzel Day!

2. THE BIG BANG AND the Universe
A look at how our universe began

3. A. The Universe Universe- entirety of space, time, matter & energy
Cosmology- the study of the structure & evolution of the entire universe.
Famous Cosmologist: research with the Black Holes (singularity), & the Big Bang.
Stephen Hawking

4. B. The Big Bang Theory
1. BBT- the universe formed in an instant, 14 billions of years ago, from a rapid expansion of matter from a state of extremely high density and temperature that marks the origin of the universe. a. Most widely accepted & supported explanation for the formation of our universe.

5. The Big Bang Theory
Makes no sense without caption in book

7. C. Light
1. Light takes the form of electromagnetic radiation (waves).

8. 2. Waves of the Electromagnetic Spectrum
a. Electromagnetic Spectrum— waves ordered by increasing wavelength

9. b. Visible light
1). The portion of the electromagnetic spectrum that human eyes can detect.
2). ROYGBIV
a. red- long waves
b. blue-short waves

10. c. Doppler shift- light shifts toward the red end of the spectrum (evidence of expanding galaxies)

11. Edwin Hubble & The Hubble Telescope

12. D. The Expanding Universe
1. Hubble’s Law
a. Hubble’s law states that the farther away a galaxy is, the faster it is moving away from us.

13. Using the Doppler Effect to Measure Velocity
Redshift
Blueshift

14. The Expanding Universe
 Hubble’s Law
• To help visualize the nature of the universe, imagine a loaf of raisin bread dough that has been set out to rise for a few hours. As the dough doubles in size, so does the distance between all the raisins. Those objects located father apart move away from each other more rapidly.

15. E. Evidence for the Big Bang Theory
1. Hubble’s Law (allows us to measure how fast the universe is moving)
2. Age of oldest known objects
a. Using the brightness, mass, color, and chemical composition we can estimate the age of stars
b. Consistent with the age of the universe
3. Cosmic Background radiation- left thermal energy from the big bang.
a. faint radiation detected in every direction by two American physicist

17. You will be turning in your journal NEXT CLASS!

21. Apollo 13 prompt-Day 1
Identify and describe some of the qualities and requirements that are needed in order to become an astronaut. Provide examples as you see them in the film.

22. # 16- Apollo 13 Space Exploration
Prompt Day 2- List & explain the tasks the Apollo 13 crew must complete in order to continue in space flight.

23. #16 Astronomy Bellringer
Use pg red text for help!
Describe the following terms & include a sketch with each term:
Comet
Asteroid
Meteor

24. Astronomy Exam Today!
10 mins to study!!!!!

25. “HOUSTON, WE HAVE A PROBLEM!”
Your communication with Earth was just destroyed by space debris, you need to get critical re-entry calculations or you and your crew will burn up when entering the atmosphere.
You must construct a tower that is EXACTLY 1 meter tall to hold your OPEN cell phone in order to get the re-entry calculations.
You have 30 minutes to get the calculations until you burn up.
You may use all the supplies in the bag, but CANNOT change any of the materials except the paper.
MISSION PTs:
Finish 1st- EC on exam (2 pts.)
Finish before 30 minutes- (1 pt.)

26. Mission Accomplished!

27. Earth Science Rocket Challenge! 2012-2013
Goal: Construct a water rocket that will stay in space flight for the longest duration. Regulations: -must use a 2 liter soda bottle for the base -cannot use explosives (I want you alive after this project) -only two people per group

29. #23: Rocket Construction Preparation
Complete the list of tasks in your composition notebook:
1. Use the diagram on pg. 686 red text (or one from the internet) to sketch an example of a rocket used by NASA.
2. Create a list of supplies for your Earth Science rocket (what do you need to bring for the main structure, fins, nose cone, parachute.)
3. The goal to keep your rocket in air the longest, provide three ideas how you will achieve this goal.
4. Research & provide a short description of how to create an effective water rocket parachute.
