Under the sea, gluing and painting

We haven't really got the paint out since coming back from SA, so Ciara got right into it when we finally did. I love it when a certain piece of what would be recycling can give inspiration, and this was what happened when I saw the cover of a music package we received in the mail. It would make a perfect under water sea scene.

Ciara gluing on sand and seaweed.
The whole scene can open and close, this is it with all the underwater creatures on.

Learning about solutions, saturated solutions and growing crystals

Eden covered dissolving, solutions, solutes and saturated solutions in her science a couple of weeks ago, so it was a lovely coincidence that our friend Tracy handed over a big box of Copper Sulphate to us, perfect for experimenting in solutions and growing crystals.
Such a lovely colour.
Mixing until the solution becomes saturated, and experimenting with what makes a solute dissolve faster in a solvent.
Put some of the solution on a saucer to grow a seed.
Wrap the seed around a piece of nylon/thread, and place this back in the main solution.
We took Tracy's advice of growing a big crystal fast. Boil the solution every day and add more copper sulphate. The crystal grew big really fast, very satisfying for a child.


The final crystal, the beauty of it I couldn't really capture on camera.
