Incredible Eye Pictures
Found a beautiful gallery of very close-up eyeball images. Incredible how much texture/depth there is inside our eyes (click to see details):
- eye2
- eye3
- eye4
- eye1
Under magnification and illumination our eye's iris really does look like the tiny sphincter that it is (aka the pupillary sphincter).
Rainbow Density Experiment
Libby and I did the Rainbow Density kitchen experiment over the weekend (instructions here). It was fun to begin to talk with her about science and how experiments are performed (we were careful to measure and observe everything that was happening).
- Getting out all of the equipment we will need for the experiment
- Stirring until the sugar dissolves into the water
- The rainbow glass (layers were beginning to diffuse already)
I am not sure Libby really understood my attempts at explaining density; understandable given my disjointed first attempt. But I think it made more sense when I said the sugar molecules were "hugging" the water molecules, and as we add more sugar the water becomes "heavier" (since more sugar is hugging it). I'm greatly looking forward to more experiments as Libby (and Cooper) grow up.
Happy Darwin Day!
