What would happen if the Earth’s gravity suddenly disappeared?

This was a recent question from my 10-year-old son… it certainly got some interesting discussions going around the kitchen table. When I opened up the question

Science News round up – January 2016.

Science News round up – January 2016.

I can’t believe that January is over already, 2016 is well underway. Here are just a few stories that made the science headlines this month:

  • And for some really BIG news, the biggest dinosaur fossil ever found, a Titanosaur, was unveiled at the American Museum of National History. For many of us not lucky enough to be able to attend in person, we got to see this spectacular species through our tv screens, documented by the wonderful Sir David Attenborough.
  • For the first time in 11 years, five planets have aligned in the morning skies: Mercury, Venus, Mars, Jupiter and Saturn; Visible to the naked eye under the right conditions.
  • British astronaut, Tim Peake made history as he became the first UK representative to perform a space walk. He even tweeted a space walk selfie.

I wonder what stories will unfold in February. Do you have any favourite science

The erupting snowman – a Christmas science experiment

The erupting snowman – a Christmas science experiment

We have had a lot of fun with this little Christmas science experiment. It is so simple, it is definitely worth a try if you have a few minutes to spare and want to give the kids a good laugh.

Here is what you will need:

  • A small jar, or similar, decorated as a snowman. We covered ours in modeling clay and painted it but you could get the kids to paint a jar or decorate it as they wish. (The jar I used here is 100ml volume but you can alter the size.)
  • Some water (I used 40mls)
  • Washing up liquid (I added about a tablespoon)
  • Baking soda (also know as bread soda or sodium bicarbonate, but NOT baking powder… they are quite different)
  • A teaspoon.
  • Something to stir with
  • White malt vinegar (I used 40mls)

Here is what you do:

  • First add the water and then the washing up liquid.
  • Next add a heaped teaspoon of baking soda.
  • Give it a good stir.
  • Add all the vinegar, quickly,  stand back and watch’s the poor snowman’s brains explode… that’s got to hurt!
  • And once your poor snowman has recovered, you can give him a quick rinse and do it all over again!

The Science bit:

Breakfast, black holes and spaghettification

I don’t know what meal times are like in other homes, but in ours they tend to be chaotic and unpredictable. Take a simple breakfast last week as an example. Nothing too fancy… there was literally only cereal on offer. But cereal boxes can be great
