Wordless Wednesday – Whirlpools

February 22, 2012 Babies

I can’t say how happy it makes me that the girls love watching the whirlpool when you pull the plug out. I love seeing the two waves on top of the water – the huge influence of such a tiny flaw. A shining, silvery hole twisting and turning in the water. Excuse the scum.

Kid Questions: Why do Fingers Wrinkle?

February 20, 2012 Kid Questions

We’re swimming several times a week and the little girl is fascinated that she turns into a giant pink sultana. She has to check each finger and toe when we get out to see how wrinkly it is. So why do our fingers wrinkle? I grew up with the old explanation, but I did some [...]

Girly Construction (Boys can do it too)

February 16, 2012 Activities

Sometimes it is brought sharply home to me that I have girls. And not just girls but fairy princesses. I don’t know if this is popular culture or some sort of cosmic payback, because I’m one of the least girly women you could think of. I don’t know if I even own high heels although [...]

Wordless Wednesday – All Around Us

February 15, 2012 Life and Living

I had a couple of examples of interesting life around us on the holidays. The first was the enormous moth above – it’s as long as my finger! It’s a hawkmoth, which comes from the Yeperenye caterpillar and is an important Dreaming spirit in the Alice Springs region. It was just in a corner of the [...]

A Farm in a Box

February 9, 2012 Activities

When we were kids we, like so many others, had silkworms. It was a fun introduction to lifecycles, responsibility and the ethical dilemma of collecting the silk easily or letting them eat their way out. Now I’ve discovered there is an even easier version where you can see the pupae rather than having them tucked [...]

February 8, 2012 Observation

OK my friends, what do you think it is? Or is this incredibly simple and you all know?

Pendulum Waves

February 6, 2012 Energy and Change

First watch this video: How cool is that? And did you like the setup in the beginning when they showed you there were no tricks, it’s just a line of pendulums of different lengths. This, my friends, is all about maths. And physics, but at this level physics is pretty much applied maths. Pendulums Pendulums [...]

Marvellous Marbling

February 2, 2012 Activities

The big girl received an art book for Christmas. Most of it is way too old for her, but she loves picking things out and then we get to work out how to modify them for her. She wanted to try marbling, but we had a few problems to solve so we tried lots of [...]

Wordless Wednesday – Rubbings

December 14, 2011 Materials

Do you have any idea how many patterned, textured surfaces you have around your home? Hundreds. Trust me. Obligatory Christmas tie-in – use rubbings to make wrapping paper, just use crayons or pencils on butcher’s paper. Kidlet’s creatively entertained and personalised paper as elaborate as you want.

Kid Questions: Why do we see the lights after they are switched off?

December 5, 2011 Kid Questions

If you stare at a light for about 30 seconds then turn it off or look away you will still see a light in front of your eyes. This is called an afterimage, or technically a positive afterimage. In the back of your eyes are lots of little cells called cones. When certain types of [...]
