wow that is crazy mad, start at the smallest or far right and go to largest.
I read what they said about the project. It seems they did it for fun. LOL extra credit for sure.
"My seventh grade science teacher showed us a size comparison video on cells, and I thought it was fascinating. I decided to make my own interactive version that included a much larger range of sizes," said Cary in an email forwarded by his mother. "It was not a school project -- just for fun. However, my science teacher loved it so much she showed [it] to the class! My brother, Michael, helped me put it on the internet."
Cary said he worked on the project, on and off, for a year and a half, getting information from Wikipedia and astronomy books. It is now spreading virally online.
Click on objects in the animation for more information. Cary said he invites people to correct any errors they find. This is his second version, he said; the first had less information in it, and the graphics needed work.
"We're not sure what we want to do after we finish school, although we're both interested in computer programming and animation," said Cary. "And astronomy is also cool!"
Asked if he thought there was a lesson to be learned from the project, Cary wrote, "I would like to say that humankind is a very small part of the universe we live in. There could be so much more out there, but we just don't know it yet."
