(E.O.A.S.1) View the video and sumarize what they see.
(E.O.A.S.2) Describe the steps that would happen if a small or large asteroid would hit in the ocean or on land.
(E.O.A.S.3) Discover more about the theory and validation how an asteroid hit the Earth 65 millions years ago and what possibly happened with the dinosaurs.


See a movie of ASTEROID 2007 HA: Watch this movie. It shows asteroid 2007 HA flying past Earth yesterday 2.5 million kilometers away.
Amateur astronomer Greg Selleck filmed the flyby from his home in Madison, Wisconsin.
At 13th magnitude ( visible with naked eye is 6th magnitude)
the space rock was an easy target for large backyard telescopes.
It is amazing that this asteroid was only discovered 2 days ago by the
MIT's LINEAR special telescopic survey on April 16th.
