1. Folders2. Notebook checks and turn in procedures3. Daily quiz sheets turned in Fridays

4. Rules and procedures5. Scale of the Universe-engage activity6. Power Point notes-if time7. Make sure to hand me your exit note!!!

SCIENCE IS AWESOME!!!!

Tear a full piece of paper in half, on one half answer #1 on the second half describe #2 about yourself.

1. Write two things that you have accomplished that you are proud of.

2. 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.

Instructions for Scale of the Universe activity:

1. You will be given a tab for an object in our universe.

2. Think about the size of your object and align yourself with your classmates in the back of the room

3. Smallest object should be closest to the Astronomy bulletin board. Largest objects should be closest to the sinks.

Answers to the correct order1. Proton

2. Oxygen nucleus3. Oxygen atom4. Red blood cell5. Eyelash6. Pupil of your eye7. Arm’s reach8. Ferris wheel9. Meteor crater in AZ10. Hudson bay11. Port Orchard12. Pluto13. USA14. Our moon15. Mercury16. Titan17. Ganymede18. Mars

Some explanation

1 An atom has a small, dense nucleus composed of neutrons and protons.2 Our Sun’s diameter (1,380,000 km) is roughly 1.8 times longer

than our moon’s orbit diameter. •3 All Oort Cloud objects, from planets in our solar system to far-

out comets, are bound by gravity to our massive sun/star. 4 On a clear dark night, we can see a few thou- sand

star/suns in our immediate “neighborhood” with the naked eye.

5 Our star “neighborhood” spirals with billions of other stars in our home Milky Way galaxy.

6 Our Milky Way circles with numerous neighboring galaxies to form a Local Group.

7 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.

8 The Virgo Supercluster floats like a dust mote among 100 billion other galaxies that comprise the observable universe.

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.

SCALE OF THE UNIVERSE

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.

Exit note

1. Which is larger, Mars or the Moon?2. Which is larger, a galaxy or a super

cluster?3. Which is larger the Solar System or

an Oort Cloud?Homework reminder: Investigate the size of your object in metric measurements.
