Water, Water, Everywhere

Core work got done nice and quickly yesterday.  Nothing really to note.

Mid-morning we were joined by friends for science.  It seems ages since our last session due to holidays and illness.  We’ve been a bit haywire since Christmas really as life has got in the way.  To be honest neither family had done our usual prep but we were both keen to get some normality and routine back.  I’m not sure masses was gained educationally, but hopefully groundwork was laid and as we dig in to the background it will make more sense.  Kids had fun though and adults managed some juvenile sniggering so all good :).

Heat was the theme.

We filled two jars with warm water, took temperature and predicted which would cool faster.  Took the temperature later and discussed why.

The big challenge of the day was getting the steam boat to work.  Had to relocate from garden to conservatory and then dismantle the boat and abandon the candle for bare matches but got there in the end and was quite impressive.

Then we were showing how heat makes things expand.  Balloon on an empty bottle, pop in hot water and the balloon inflates.  Pop it in iced water and it deflates and flops (rather comically :D).

They were aiming for ‘thoughtful, scientist faces’!

Finally we looked at convection currents by boiling some sequins and watching them rise and fall.20150429_8

We had a trip to the park before friends went home.

After a late lunch Sam helped with some crafts for work.

Then we went swimming after Jack got home.  Not been swimming for ages and very unfit.  Trying to find a way to get it in to schedule regularly.

Home Sam swallowed tea and was off to Cubs where he went pond dipping and found a dead shrew.  I managed some work, guiding admin and a check of camping supplies.

Long but good day.
