A Few Days...

Gymnastics.

Playing at the park and chatting to newly made friends

Reading Heidi

There was a party going on here today (Danielle's sign saying Party here today)



Pass the parcel for all their friends


Animals had a bit of a game going on





This was a cool experiment! It used a plate of milk and we dropped in a little food colouring. This experiment shows about surface tension - the milk is denser than the colours, so they just sit suspended towards the top amongst the fat of the milk. We then dropped in a few drops of dishwash liquid. The colours went crazy and were zooming around the plate! What happened was that the dishwash liquid broke the surface tension and began to break down the fat and therefore making way for the colour to move around, the more fat that got broken down, the more the colours could move (well, that was one explanation I read). We did notice that it took quite a bit for them to blend. Unlike mixing colours together and just ending up with a murky brown, the colours just swirled and worked their way in between each other and very gradually blended. Even after about 5mins of gently moving the liquid with the spoon we ended up with a marbled effect.

(oops! Non friendly video, best with sound off lol - next time I should watch it properly before posting!).



Questions about why we could see the moon during the daytime lead onto reading up about moon cycles (how many weeks in a calendar month, months in a year etc) and the Earth orbitting the sun. Nathan plans on asking his Grampie how many times he's been around the sun next time he sees him.

We've had friends pop in for a visit.

A gorgeous day meant a visit to the local outdoor pools for the first time this season.

hehehe - did you listen to that video? It isn't family friendly!
I expected scientific explanations from a boring monotone narrator... instead you get a bunch of surfie adults saying 'gnarlee man, F***ing gnarlee'. Too funny :)
