Week of February 11th
The picture above is an image of an asteroid  (space rocks baseball-sized or larger),  streaking past the Earth -  taken by the Hubble Space Telescope in 1998.  Many tons of space dust,(meteoroids), hit the Earth's atmosphere each day; baseball-sized space rocks burn up in the atmosphere each day - they look like the blue-streak pictured above - we call them meteors.  Every 1,000 years a space rock, about 100 km across, hits the Earth causing huge global consequences - we call these meteorites.  Every 1 million years or so, a space rock hits the Earth that seems to change everything! 
 Our Week
Monday:  1.  Check/discuss Telescope Project reviews 2.  Finish Orion Act. together 3.  Video: "Stopping Armageddon" - video notes' sheet due Tuesday

Tuesday:  1.  Finish video - if needed  2.  "Tennis-Ball Derby" - data sheet checked Wed.



Wednesday:  1.  Finish Tennis Ball Derby - discuss findings  
2. Read/go over    p. 13-14 and p. 18-20 in PBIS Astro.  3.  Work on Crater Lab Design - due Friday (tentatively)

Thursday:  Crater Lab

Friday:  Crater Lab 

Questions of the Week
Pictured above is a picture of a meteor shower from 100 years ago!  Hasn't technology come a long way!  What constellation do you see in the top left???  
Saturn's small moon Mimas with a huge crater! 
Asteroid Vesta - one of the largest space rocks - located in the Asteroid Belt - between the planets of Mars and Jupiter.  What has happened to Vesta as it as been floating around the Sun?
Pictured above is technology called a Gravitational Tractor - this is a proposed idea for redirecting an asteroid that may be heading for the Earth to shake us up a little too much.  How do you think this would work?

 Where is the best place to look for meteorites?

    1. 3a. The Gravitational Tractor works by having a very dense element to pull it towards the tractor.

  2. The constellation is Orion. It has had many meteor impacts. It will affect the gravitational pull of the asteroid. The best place to look for meteors is the south Pole.

    -Best place to look for meteors: North and South Poles
