- Attachment: The Egg shell
- Microscopes are amazing with the new technologies we have today. We can learn to visualize a smaller and smaller world. This world of the tiny becomes a beautiful and intriguing place to visit.
- The picture attached is an egg shell. This is the cross section of the shell with the inside of the egg shell being at the bottom.
- This picture was taken with “ electron backscatter diffraction” microscope. Beams of electrons were fired at the edge of the shell and the pattern created by the electrons that bounced off was detected and recorded. The image was then created in a computer with each color representing different ways the atoms in the shell were positioned.
- The shell is 0.6 millimeters thick. And the strongest part of the shell is red color. These atoms were arranged up and down like Greek pillars that show up as red panels.
- Each type of bird egg has an unique shell pattern. The different color schemes created tell scientists which bird laid the egg. This particular egg was laid by a prehistoric flamingo between 5.33 and 23.03 years ago. It is an old egg.
- The image is a whole new way of seeing. You would have never identified this picture as an egg shell, right?
