Lightning Never Strikes Twice

Continuing our Fact or Fable series, today we take a look at the saying ‘Lightning never strikes twice’, with our Science Editor Samantha Gouldson investigating.

Lightning forms when excess amounts of positive and negative electric charge build up in storm clouds. This causes sparks, kind of like static electricity. Sometimes the sparks jump between the clouds but often they jump between the clouds and the ground.

It’s not just thunderstorms that have lightning either; snow storms, sand storms and even the clouds produced by erupting volcanoes can all cause lightning.

The idea that lightning doesn’t strike twice is a popular saying but one that it’s easy to disprove.

Fact or Fable? Most body heat is lost through the head

It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.

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?

What is the Orionid Meteor Shower?

This October Earth will be passing through the tail of Halley’s comet, which will mean a shower of meteors flashing across the night sky. Our science editor Sam Gouldson explains.

What is Halley’s Comet?

A comet is a lump of rocky particles, ice and dust all bound together like a dirty snowball. When the comet nears a star, its surface transforms from a solid to a gas. The star’s light shines through these gases and makes them visible to observers as a fuzzy cloud around the comet’s centre, and a tail streaming out behind.
