Hi all,
For homework tonight, please watch online the short video "Powers of Ten", which can be found here: http://www.powersof10.com/index.php?mod=register_film. You need to provide your e-mail in order to view the film. If you don't want to do that, look it up on YouTube - it's there.
After you watch the video, please respond to these questions on a single side of a large index card.
1. What's the best metric unit (meters, millimeters, micrometers, etc.) to measure the following items: (a) atoms (b) a skin cell (c) bacteria cells (d) viruses (e) mitochondria (f) width of a human hair (g) a DNA molecule (h) an atom
2. Why do you think are cells so small? Is there an advantage?
This is due tomorrow. Happy watching.
-Mr. Hill
