chris and i stayed up a bit too late with playing online agricola with the babs last night [i won - yay!] SB also had a late bedtime, having read a book she then got scared by, so had to have time to read a more comforting book, so was v tired today!
whe we got up, it was snowing – again! and quite hard, but a quick check suggested no snow at merry’s, so the science stuff was gathered and we set off. we were also the firsterers there!! actually, due to a number of circs we were 2 families down and one family up, and that worked pretty well! Did science in dribs and drabs, as it was basically setting it up and then watching what happens.
as we are on a ‘biology’ term, and roughly looking at microbiology, today we looked at yeasts. We have done a fair bit of discussion on and off about bodies, energy sources and then lungs, oxygen and carbon dioxide, so we did a bit of a recap. there was surprise that yeast might be ‘alive’ so this wasn’t a simple chemical reaction. that actually what was happening was the yeast would be using sugar to fuel the division into 2 [actually this is a bit of a simplification, as yeasts actually bud off rather than divide like bacteria] that they are single celled organisisms of funghi. we knew what it was used for, and i briefly touched on the krebbs cycle without naming and shaming it, saying effectively to make the energy, a gas was given off as a waste product. we had quite a talk about the various gas possibilities, but mostly settled on CO2, partly because this is something we breathe out as a waste, and partly because i had brought along some lime water to test for co2!! so we used my beautiful new erlenmeyer beakers and placed 5 spoons sugar, one heaped yeast and 250mls warm water and topped off with a balloon. soon enough this began to fill with ‘the gas’ and then each got a chance to mix ‘the gas’ with lime water – which rather fabulously went cloudy! and also to put a lit match into it – which v satisfactorily immed went out. so we learnt a bit about micro orgs, their needs, and waste products, and how to test for them. fab! this book suits this experiment pretty well, and we read it again earlier this week
I also did some of the sampler sewing – not as well as Merry! Kty did french, the children voluntarily did some music, and Zoe was pasta and tea maker – thanks! there was no snow at merry’s, tho it did snow on and off. we got back well in time for brownies – still snow here!
BB had her face painted and then decided she was tired [she fell asleep in the car on the way home whilst SB and I sang along to serge - above] and watched star wars whilst i snoozed.
SB was at brownies making valentines biscuits and then judo. this is the game of 2 halves, as this owl has a very brusque and brisk nature, and is just one of those busy women who perhaps SB isn’t so used to. so she asked to get changed in her toilet [it was at the big house for cooking] and j agreed, but whilst she was doing it, she was called for, and couldn’t hear so then got told off. then found someone else had taken her biscuits as they looked nicer, which she had made for me. SO loads of tears. Arrgh. I know she was prob stressed, but this isn’t the first time SB has cried. And yes Sb wears her heart on her sleeve and has no thickness of skin to speak of, but i do think that this being so a bit of compassion over the taken biscuits and actually, since sb had asked to change in the loo… oh well. we had a long discussion about different folks, and that j would prob be surprised that that exchange had made sb cry… btw Merry and katy, SB says she just isn’t used to shouty ppl as we and you don’t shout! Anyway, lots and lots of hugs on return, watching magic school bus inside ralphie episode, and to bed as a happy girl again.
