What is a Stick Bomb?

11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.
If you are thinking ‘What?’ then watch the rest of his TEDx talk to find out what a ‘Stick bomb’ is and what makes them jump.

The Fall – A Short Story in Three Parts – Part Three

This is the third of a three part story by 10 year old Alice. Read Part One and Part Two first.

 

My view is hazy, but I can work out the blurry shape of a nurse, standing by my bed. My eyelids shut; the light was stinging my eyes.

“Hello?” The voice is soft. I decide to answer.

“Hello,” I answer.

“I’m Josie,” says the nurse, pulling up a chair beside the bed. “What’s your name?”

“Kieran,” I reply, chewing my lip.

“Well, Kieran, you’ve been through a lot,” she says. She feels my forehead. “You had a raging fever you know. How do you feel now?”

Tomboys and Girly Girls

The mother of eight year old Isabella wrote about buying toys without glitter, and searching for ‘girl’ clothes in colours other than pink, which got us thinking about the term ‘tomboy’.
What do you call a girl who isn’t a girly-girl? Some people would say, ‘a tomboy’, but does that imply that the girl isn’t a real girl, and do we need a label for this anyway?
Perhaps we should let toys be toys, as this campaign demands, and sell clothes without ‘boy’ or ‘girl’ labels. What do you think?

Winter Wonderings – Are Snowflakes Really All Different?

 

It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.

However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.

The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!
