Biology: Metamorphosis! From Chrysalides to Painted Ladies

What a drama filled week it has already been for our for newly winged friends.  We started out with four pupa.

Monday morning - voila!  Our first butterfly. Then late Monday, we had another come mostly out of its Chrysalis. 

But Alas, tragedy - the second butterfly got stuck to a bunch of the caterpillar silk that had been attached to its Chrysalis by some of the other caterpillars.  Unfortunately, I had forgotten that the directions had stayed to clear away the silk before transferring the Chrysalides to the butterfly enclosure. 

After giving the butterfly a day and a half to figure out what it was doing, Erik finally decide to intervene with a pair of safety pins and was able to release the butterfly from the silk.  Unfortunately, by then its wings had already hardened without ever having been unfurled.  (The silks had bound his wings in.)  And so we found him this morning, having spent the night at the bottom of the cage, still twitching, but still crumpled up, unable to move wings or most of her/his legs (the ones which were tucked silk in the wings).

The last two remaining butterflies came out over night, last night.  One of them spent a good part of the day with its abdomen still stuck inside the Chrysalis.  Fortunately, it faired a bit better than pour crumpled butterfly.  It had it's wings unfurled.  However Erik did have to rescue it, again with the safety pins, and there is a pronounced twist to its wings - so it will have to compensate when flying.


We plan on releasing all three butterflies as soon as the weather permits.  Meanwhile, I jerry-rigged up small sugar-water filled glad-ware container with a construction paper flower, in hopes that the butterflies would sustain themselves on our meager offerings until conditions were favorable for flight.

Grape Hyacinths on my mind...

Grape Hyacinths seem to go crazy around these parts - much to the delight of W who has been talking about making a grape-beaded bracelet for ages.  Still haven't gotten around to the beaded bracelet, but this
will have to do for now.

Pipe cleaners + grape hyacinths = bracelet.

Tea Party

N has really been getting into pouring things and W and Dada have been reading Alice (In Wonderland and now Through the Looking Glass)...  What better way to wind down the evening than have mini tuna fish salad sandwiches, mini avocado and cream cheese sandwiches and some homemade vanilla maroons?  And don't forget of course - the tea (iced for the warm weather) - Wild Berry Zinger this time.



Dressed for the party...



Musn't forget the cookies.






Taking great care to pour and spoon neatly - like big ladies!  Our tea parties have come a long way since pouring all over the table and pouring back and forth between the sugar bowl, the creamer, various cups and the teapot itself.  That is not to say that silly stuff doesn't still happen - but we managed to keep it down to a few slivers of celery being added to a few of the tea cups.  The key was to keep the party relatively short, and to remove the temptation of the sugar bowl and creamer once the interest in drinking the tea had tapered off...

Biology: Our first Chrysalis!

We had been noticing that one of our Painted Lady caterpillars had been hanging upside down from the ceiling of their container for about a day.  It was hanging in the classical "j" shaped posture.  and this morning W checked on the caterpillars and sure enough, this was the first one to pupate.  Sooooo exciting!  We expect the rest will follow in the next couple of days.  They should emerge from their chevaliers within a week plus of pipetting.

Chemistry: Distillation at Home

Our first homemade still - trial-run getting ready for our co-op lesson on the water cycle, our water purification system, and the different phases of water.  It isn't very efficient, but it has produced some water. 






Later on we tried another method, reported online to have greater yields (reminiscent of a solar still only with a round-lidded pot).  Use an inverted rounded lid to cover the pot (containing the initial aqueous solution). Boil the water and suspend the receiving container in a colander in the same pot (so as to keep the receiving container cooler than the boil below).  Add ice to the top of the pot and voila!  You have a nice much more efficient at-home still.  Not as pretty as the contraption with straws, but much more reliable, unless one wants to invest in actual chemistry equipment (which would be super-awesome but expensive, and better used for more advanced chemistry lessons on distillation).

Mama Projects: Adventures in Knitting

W's Violet Swirl Ribbed hat.  Okay, so the swirl didn't quite pan out...it's more of a scribble hat.  But it's my very first knit flower really turned out - loved it!  The center stamen was W's idea.

Art Projects: Rain painting

Okay, here it goes again.  Hopefully a more readable post...  What better way to get the girls to enjoy the rain than to add a little tempura paint powder and paper and let them have at it?  It was a smashing hit.  I'm thinking of trying kool-aid next time...
