  1. September 6 Astronomy day 2

  2. Agenda • Syllabus • Finish Intro • House keeping • Folders • Notebook checks and turn in procedures • Daily quiz sheets turned in Fridays • Rules and procedures • Scale of the Universe-engage activity • Power Point notes-if time • Make sure to hand me your exit note!!!

  3. Science is Awesome!!!!

  4. Snow balls • Tear a full piece of paper in half, on one half answer #1 on the second half describe #2 about yourself. • Write two things that you have accomplished that you are proud of. • Write two things that you would like to share about you that might not come out in class (what makes you unique) that you would like others to know.

  5. Symphony of Science • http://www.youtube.com/watch?feature=player_embedded&v=akek6cFRZfY

  6. Scale of the Universe How big is big? How small is small? http://www.youtube.com/watch?v=17jymDn0W6U http://scaleofuniverse.com/

  7. Instructions for Scale of the Universe activity: • You will be given a tab for an object in our universe. • Think about the size of your object and align yourself with your classmates in the back of the room • Smallest object should be closest to the Astronomy bulletin board. Largest objects should be closest to the sinks.

  8. Answers to the correct order • Proton • Oxygen nucleus • Oxygen atom • Red blood cell • Eyelash • Pupil of your eye • Arm’s reach • Ferris wheel • Meteor crater in AZ • Hudson bay • Port Orchard • Pluto • USA • Our moon • Mercury • Titan • Ganymede • Mars • Earth • Jupiter • Moon’s orbit • Proxima Centauri • Sun • Earth’s orbit • Solar system • VY CanisMajoris • Kuiper belt • Cat’s Eye Nebula • Oort cloud • Pillar’s of Creation • Eagle nebula • Milky way galaxy • Our local group of galaxies • Virgo Super cluster • Observable universe

  9. Some explanation • An atom has a small, dense nucleus composed of neutrons and protons. • Our Sun’s diameter (1,380,000 km) is roughly 1.8 times longer than our moon’s orbit diameter. • • All Oort Cloud objects, from planets in our solar system to far-out comets, are bound by gravity to our massive sun/star. • On a clear dark night, we can see a few thou- sand star/suns in our immediate “neighborhood” with the naked eye. • Our star “neighborhood” spirals with billions of other stars in our home Milky Way galaxy. • Our Milky Way circles with numerous neighboring galaxies to form a Local Group. • Our Local Group rotates near the outer edge of many other groups of galaxies with the Virgo Group near its center. This huge, gravitationally bound “group of galaxy groups” is called the Virgo Supercluster. • The Virgo Supercluster floats like a dust mote among 100 billion other galaxies that comprise the observable universe.

  10. Homework • Find out the size of your object. Try to find out both the diameter and circumference of your object. If it is not spherical imagine a sphere around it and report back next class.

  11. http://apod.nasa.gov/apod/ap120312.html Scale of the Universe

  12. Large scale structure of the universe • http://www.youtube.com/watch?v=VJpC_oQQxPI • This is a five minute large-scale structure of the Universe shown in 3 different scientific observation projects: • Sloan (Digital Sky Survey), Millenium (3D model of the universe) and Filaments grown process simulation.

  13. Exit note • Which is larger, Mars or the Moon? • Which is larger, a galaxy or a super cluster? • Which is larger the Solar System or an Oort Cloud? Homework reminder: Investigate the size of your object in metric measurements.
