Scrambled Eggs

GOOD EGGS: During our foray yesterday into egg science and how you can tell a fresh one from a bad one, of course we encountered some eggsellent resources. By following a few links, we wound up on an activity called "Take an Egg for a Spin" on the (very cool!) Science of Cooking site. 



I hard boiled an egg so we could do the experiments.


In the first one, you take two eggs, and get them spinning on a table. You stop both eggs and release them and then watch what happens. ...
Imagine the kids' surprise when the raw egg started spinning again. Why? Momentum! The egg's liquid center didn't stop when we stopped the vessel/shell. It worked every time.


There was also an experiment with just the hard boiled egg. The challenge was to get it spinning super fast (>10 revolutions per second!). Once it’s spinning fast enough, and you let go, the egg rises up on one end, spinning like a top. Why? Apparently it’s the friction between the eggshell and the tabletop. It pushes the spinning egg, The friction slows the egg down some, and contact point with the table moves off center. The egg then begins to twist as it spins, and one end rises up (for a few seconds at least).

We were so happy when it got up on end! 
Talk about an easy, cheap, fun science eggsperiment!

AYE, AYE, CAPTAIN: First thing this morning, we tuned in to a Canadian Space Agency broadcast featuring William Shatner (Captain James T. Kirk) and Chris Hadfield, current commander of the International Space Station. Talk about when worlds collide!

AFTERNOON DELIGHT: Weather-wise, today was an absolute gem! 
Sunny, and unseasonably warm, with no wind. Delightful!

We celebrated it by parking in 'The Village' and walking several blocks, to the library. Here are the kids entering a park between our car and the library.
Once we got to the library, there, under a boulder, we spied our first blooming crocus of the season. Sweet! We walked back to the car, and didn't quite have our fill of it all, so we took the extra minute to drive out to the bluff and took in the sights.
Glad we did. :)

This afternoon, CJ's BFF from kindergarten joined the kids' yoga class for the first time. Fun!
